Recovery of acetyl cholinesterase inhibition by Methanolic Bark Extract of Ac...Innspub Net
Organophosphates (OPs) pesticides are reported to cause acute poisoning because of their ability to inhibit acetyl cholinesterase enzyme (AChE). Available antidotes drugs are atropine sulfur, Pralidoxime (2-pyridine aldoxime methyl chloride) and diazepam, which act to recover OP-AChE inhibition. These are controlled drugs not easily accessed and very expensive. In this present study Acacia nilotica was assessed for its antioxidant activity, and in vivo AChE depression and recovery from OP-AChE inhibition. The mice were exposed in three different OPs including chlorpyrifos 480g/l (CPF), Fenitrothion 10g/l (FNT) and Profenophos 720g/l (PFP). The methanolic bark extract of A. nilotica had a substantial increase of absorbance readings from 2.895±0.0032 to 3.716±0.0259 compared to standard (ascorbic acid) from 0.108±0.0033 to 1.468±0.0297 at P<0.05. AChE depression and recovery were assessed by using the AChE test mate kit to analyze blood collected from the mice’s tail. Recovery effect under crude methanolic extract from A. nilotica, ascorbic acid and normal feeding were compared with the untreated group. Results have shown that there is a significant decrease of AChE level from Day zero to 14th day in all treated groups of CPF, PFP and FNT which indicate poisoning. Significance of AChE recovery observed only in male mice in all treatment groups. This is a first study to assess and report the antioxidant activity of stem bark methanolic extracts of A. nilotica in controlling organophosphate pesticide toxicity in mice, hence further studies on isolation of active compounds are recommended.

Wild hops (Flemingia strobilifera Linn.) is a shrub belonging to Fabaceae family. The leaves of F. strobilifera are commonly used by the Subanen, the indigenous group in Lapuyan, Zamboanga del Sur, Philippines to treat inflammation. In this study, the hydromethanolic (80%) and aqueous leaf extracts of F. strobilifera were evaluated for their antioxidant activity and total phenolics content. The active semi-volatile components of 80% methanol leaf extract were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). DPPH radical scavenging activity was used to determine the potential of this plant as anti-oxidant. Total phenolics content was determined using Folin-Ciocalteu reagent and calculated as gallic acid equivalence. GC-MS analysis revealed the presence of eight compounds. Both the 80% methanol and aqueous extracts of F. strobilifera showed significant scavenging activity with low IC50 values of 0.299 mg/mL and <0.25 mg/mL, respectively. There was positive correlation between the scavenging activity percentage and the total phenolics content only in the aqueous extract of F. strobilifera while 80% methanol extract showed negative correlation between inhibition percentage and total phenolics content which can be attributed to the solvent used and method used in quantification of phenolics. Nevertheless, the results suggest that these leaf extracts are potent source of antioxidant compounds and may serve as natural anti-inflammatory agents.

The phytochemical investigation of Linum usitatissimum, family Linaceae, resulted in the separation and
identification of a lignane, 8–5' neolignan 1 (dehydrodiconiferyl alcohol-4-β-D-glucoside), in addition to
identification of many compounds by the GC/MS technique. The antimicrobial activities of hexane, methylene
chloride and butanol fractions were comparable to ampicillin. The activities against E. coli were 29.2%, 37.5%,
and 66.7%, respectively; against S. aureus were 45.4%, 36.4% and 63.6%, respectively, and against C. albicans
were 26.9%, 46.1% and 73.1%, respectively. Antioxidant activity was assessed by ABTS method. It decreased
in the following order: ascorbic acid > butanol fraction > methylene chloride fraction > hexane fraction. The
cytotoxicity against HePG2 was found to be “moderate” for butanol and methylene chloride fractions, and
“weak” for the hexane fraction. The cytotoxicity against MCF-7 was found to be “strong” for butanol fraction,
and “weak” for both hexane and methylene chloride fractions. The lignane-rich subfraction, Lu 3d was
incorporated into pluronic nano-micelles using nanoprecipitation technique through a modified procedure.
The physicochemical characteristics of the developed Lu 3d-loaded nano-micelles such as particle size,
potential and morphology were determined using DLS and HR-TEM. The average diameters of the prepared
plain and Lu 3d-loaded pluronic nano-micelles were found to be 207 ± 12 and 225 ± 18 nm, respectively. The
encapsulation of Lu 3d into nano-sized particles has enhanced their aqueous dissolution and consequently
improved their bioavailability. Nanoformulation of Lu 3d led also to a stable colloidal dispersion with a strong
green color, indicating its homogenous distribution in the aqueous medium at a significantly higher
concentration than that obtained using other solvents.

The root extracts of Acanthus ilicifolius L finds a prominent place in folk medicine. In this study, we
extracted alkaloid, flavonoid, tannin and total phenols in benzene, ethyl acetate, acetone, methanol and
ethanol, their antibacterial activity and antioxidant activity was evaluated. The antioxidant activity is executed
by FRAP assay and agar well diffusion method is done to study the antibacterial activity against Enterobacter
aerogenes, Enterobacter cloacae, Escherichia coli, Bacillus subtilis, Staphylococcus aureus and Streptococcus
pyogenes. The antibacterial activity of all the extracts was compared with standard antibiotic gentamicin.
The Minimum Inhibitory Concentration [MIC] was determined by serial dilution method. Alkaloids are rich in
acetone and Flavonoids are high in methanol extracts. The acetone extract showed higher antioxidant activity,
while benzene extract was identified to contain lower antioxidant activity. The extent of inhibition by the root
extracts diverge between the solvents used, among them ethanol extracts exhibited higher level of inhibition
against the gram positive test cultures compared to gram negative test cultures employed. Whereas, the acetone
extracts efficacy is more on gram negative test cultures than the gram positive cultures. The MIC was found to
be between 1mg/100µl to 5mg/100µl. This study gives the source for purification and characterization of
bioactive principles that possess antioxidant and antibacterial action from the root of Acanthus ilicifolius.

Ijb vol-16-no-1-Recovery of acetyl cholinesterase inhibition by Methanolic Ba...Innspub Net
Organophosphates (OPs) pesticides are reported to cause acute poisoning because of their ability to inhibit acetyl cholinesterase enzyme (AChE). Available antidotes drugs are atropine sulfur, Pralidoxime (2-pyridine aldoxime methyl chloride) and diazepam, which act to recover OP-AChE inhibition. These are controlled drugs not easily accessed and very expensive. In this present study Acacia nilotica was assessed for its antioxidant activity, and in vivo AChE depression and recovery from OP-AChE inhibition. The mice were exposed in three different OPs including chlorpyrifos 480g/l (CPF), Fenitrothion 10g/l (FNT) and Profenophos 720g/l (PFP). The methanolic bark extract of A. nilotica had a substantial increase of absorbance readings from 2.895±0.0032 to 3.716±0.0259 compared to standard (ascorbic acid) from 0.108±0.0033 to 1.468±0.0297 at P<0.05. AChE depression and recovery were assessed by using the AChE test mate kit to analyze blood collected from the mice’s tail. Recovery effect under crude methanolic extract from A. nilotica, ascorbic acid and normal feeding were compared with the untreated group. Results have shown that there is a significant decrease of AChE level from Day zero to 14th day in all treated groups of CPF, PFP and FNT which indicate poisoning. Significance of AChE recovery observed only in male mice in all treatment groups. This is a first study to assess and report the antioxidant activity of stem bark methanolic extracts of A. nilotica in controlling organophosphate pesticide toxicity in mice, hence further studies on isolation of active compounds are recommended.

GC-MS Analysis and Evaluation of In-vitro Antioxidant Potential and Total Phe...Innspub Net
Wild hops (Flemingia strobilifera Linn.) is a shrub belonging to Fabaceae family. The leaves of F. strobilifera are commonly used by the Subanen, the indigenous group in Lapuyan, Zamboanga del Sur, Philippines to treat inflammation. In this study, the hydromethanolic (80%) and aqueous leaf extracts of F. strobilifera were evaluated for their antioxidant activity and total phenolics content. The active semi-volatile components of 80% methanol leaf extract were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). DPPH radical scavenging activity was used to determine the potential of this plant as anti-oxidant. Total phenolics content was determined using Folin-Ciocalteu reagent and calculated as gallic acid equivalence. GC-MS analysis revealed the presence of eight compounds. Both the 80% methanol and aqueous extracts of F. strobilifera showed significant scavenging activity with low IC50 values of 0.299 mg/mL and <0.25 mg/mL, respectively. There was positive correlation between the scavenging activity percentage and the total phenolics content only in the aqueous extract of F. strobilifera while 80% methanol extract showed negative correlation between inhibition percentage and total phenolics content which can be attributed to the solvent used and method used in quantification of phenolics. Nevertheless, the results suggest that these leaf extracts are potent source of antioxidant compounds and may serve as natural anti-inflammatory agents.

Phytochemical and antioxidant studies of methanol and chloroform extract from...shailendradhakal
This research was carried out with the aim of phytochemical analysis and determining antioxidant activity present in methanol and chloroform leaf extracts of Azadirachta indica. Due to its potential in curing various ailments as well as wide spread application of antioxidant activity such as in the field of cosmetology, the plant was selected for the study. The total phenolics contained in the plant extracts were also studied which are responsible for the antioxidant activity.
ABSTRACT- Secondary metabolites or phytochemicals from plants have eminent pharmacological activities such as
anti-oxidative, anti-allergic, antibiotic, hypoglycaemic and anti-carcinogenic. These secondary metabolites protect the
cells from the damage caused by unstable molecules known as free radicals. They can inhibit oxidation of free radicals in
both human body and food system. Food industry uses both natural and synthetic antioxidants to extend shelf life of
products. But the application of synthetic antioxidant has been limited due to its carcinogenicity. Recently research is
being focused on fruit materials, which are considered rich source of antioxidant compounds. In this study the
phytoconstituents of seed extracts of two varieties of Cucumis melo L, namely Cucumis melo cantalupensis and Cucumis
melo reticulatus, were studied for their antioxidant property by DPPH free radical scavenging method. In this
investigation, chloroform, petroleum ether, acetone, aqueous and ethanolic extracts of the fruit seed were made using cold
extraction process. Phytochemical study reveals that anthroquinones, quinines, cardiac glycosides, terpenoids, phenols and
steroids were present in aqueous extract of both the samples. The total phenolic content of their seed extracts were found
to be 8.8 mg GAE/g of dry sample and 9.2 mg GAE/g of dry sample respectively. The phenolic content was found to be
linearly proportional to the antioxidant ability of the samples.

Flora is systematic enumeration of plant species in a given community of a given ecosystem. It reflects the quality as well as the health of the ecosystem because the floral community are the producers which support the growth and development of ecosystem. It reflects the inflow of nutrients and recycling processes through bio-geochemical processes. Indiscriminate use of different chemicals and articles for different purposes produced by different leading factories for the modern development of human societies causes threat to the environment and loosing the biodiversity which significantly destroying the environment rapidly. The main reason is increasing load of human population which damaging the environment and degrading the ecosystem by pollution directly or indirectly. The present paper reflects the 57 floral elements under 29 families and the community structure including eco-degradation process which could be a starting point of extension through community research by a group of workers in future. Hope that interested people will come and take that opportunity to record the problems for future study and assessment about the dwindling ecosystem for our existence at Lalgarh.
Although ATP production is very important for mitochondria, little is known about the actual rate of production and the value of “unit of currency” for mitochondrial energy transactions. “Unit of currency” for all transactions in general is named “quantum” in Physics, and no value of ATP quantum is accurately given in bibliography, other than rough estimates. This work focuses to calculating produced energy unit in mitochondrial metabolism (Quantum for ATP, or QATP for sort) and the rate of ATP production (power of “mitochondrial factory”)
High Prevalence of Vitamin D Deficiency Among Saudi Children And Adolescents ...IOSRJPBS
Background: Vitamin D inadequacy constitutes an increasingly recognized comorbidity among Saudi populations. There were limited data about its prevalence in Saudi children with type 1 diabetes mellitus (T1DM). Aim: To evaluate the prevalence of vitamin D deficiency among Saudi children and adolescents with T1DM in Albaha region, southwestern of Saudi Arabia. Methods: A cross-sectional study was conducted on 117 Saudi children and adolescents with T1DM. These patients were recruited from Albaha diabetic center, Saudi Arabia. The range of age of the participants was 1 –18 years.. All participants were subjected to history taking including, age, gender, duration of diabetes, clinical presentation at the onset of diabetes. Measurement of serum 25 hydroxy vitamin D was done in all participants. Results: There were 117 Saudi children and adolescent with T1DM, 52 (44.4%) were boys, and 65 (55.6%) were girls with a mean age 8.8 ± 3.4 and 9.2 ± 3.9 for boys and girls respectively (p=0.52). The mean serum 25-hydroxy vitamin D levels among them was 17.1± 10.1 ng/ml and the prevalence of vitamin D inadequacy was 88.9% (59.9% of subjects had vitamin D deficiency and 29 % had vitamin D insufficiency) and 11.1% had sufficient levels of 25-hydroxy vitamin D. There was a significant difference in vitamin D level among different groups of vitamin D level (p˂ 0.001). The prevalence of Vitamin D deficiency was greater in the girls with 34.2%, as compared to 25.6% among boys. Vitamin D deficiency was more common among children in the range of age 1-10 years (52.1% vs 36.8%). In vitamin D deficient group, the mean levels of vitamin D were significantly lower in patients presented with DKA as compared to those presented with hyperglycemic symptoms (p= 0.016). Conclusion: Vitamin D deficiency is common in Saudi children and adolescent with T1DM in Albaha region. This is more common in girls and in the younger age groups. Therefore, screening for vitamin D deficiency, creating awareness to increase sunlight exposure, increase the fortification of food products with vitamin D and vitamin D supplementation for these patients should be warranted to prevent future morbidity.

A Review on Different Benefits of MushroomIOSRJPBS
This paper reviews mushrooms. In this paper, nutritional and medicinal values, other uses of mushrooms were discussed. Mushrooms have been important in human history as food, as medicine, as legands, and in folk lore and religion. Mushrooms are basically consumed for their texture and flavor. They have recently become attractive as health - beneficent food and as sources for the development of drugs. Many higher mushrooms are known to contain a number of biologically active components that show promising antitumor and immunomodulating, cardiovascular, hepatoprotective, hypocholesterolemic, antiviral, antibacterial, antiparasitic and antidiabetic effects. Nutritional value of mushrooms lies between that of meat and vegetables. The rich source of proteins, vitamins and minerals and low in fat content (2-8%) unique chemicals constitution of mushrooms makes them low calorie food 8 and choice diet for those suffering from hypertension, arthrosclerosis, diabetes, obesity. Mushrooms play a role in the development of new biological remediation techniques and filtration technologies (e.g. using fungi to lower bacterial levels in contaminated water). From the review it was observed that developing countries should harness the potentials of mushrooms as this would boost the revenue income and healthy living. It is hoped that this paper would add to existing information on this fungus

This study was carried out to investigate the effects of some vegetables (Diplazium sammatii, Moringa oleifera, and Justicia insularis) as additives on the growth parameters of Pleurotus ostreatus cultivated on two substrates; banana leaves (BL) and banana leaves/sawdust (BL/SD). The substrates were amended with these vegetables at different concentration levels (0 g, 5 g, 10 g and 15 g). Spawn running was completed in 30, 35, and 40 days in banana leaves, banana leaves/sawdust and the control respectively. Parameters assessed included area of pileus, number of fruit bodies, fresh weight, dry weight, length of stipe and girth of stipe. Higher mean values for fresh weight (21.69 g), area of pileus (42.58 cm2 ), length of stipe (5.10 g) and girth of stipe (4.30 g) were obtained from BL substrate treated to 5 g M. oleifera leaf powder. These values were significantly different from values obtained for other plant additives. Considering the number of fruit bodiesthat emerged on BL/SD substrates, the control produced more fruit bodies than the substrates with additives. The best performance in BL/SD substrates was observed when the substrate was treated to 10 g J. insularis in some of the parameters assessed. These included fresh weight (20.64 g), number of fruit bodies (8.00) and stipe girth (3.44 cm).Other parameters like area of pileus (36.08 cm2 ) and dry weight (2.39 cm), control had a better performance. While for length of stipe, 15 g M. oleifera leaf powder had the highest mean value that was significantly different (P≤0.05) from what was observed in substrates amended with other additives. It is therefore evident that these vegetables have high potential for utilization as additives or supplements for growing of Pleurotus ostreatus especially when using BL as substrates. In addition, substratesadditive concentration combination played a significant role in selective organ growth of the test mushroom.
Dermatoglification Analysis for Selection and Training of Sports TalentsIOSRJPBS
: The term sports talent can be defined as the individual who, through his inherited and acquired conditions, has a special ability for sports performance, above the average of the general population. Fingerprints are genetic markers and can function as indicators of sporting talents. The objective of the present study was to use dermatoglyphics to identify the genetic-physical profile of soccer athletes. Twenty-four athletes belonging to the Palmeiras Sports Society Athletes' Capture Center participated in this study in the Nordeste sub-category category 16. The dermatoglyphic protocol of Cummins and Midlo (1961) was used. Standard fingerprint indices were calculated: the number of drawings for the 10 fingers and the delta index (D10). We also analyzed the types of digital formulas that indicate the representation in individuals of different types of drawings. Based on the classification of Fernandes (2002), the group presented somatofunctional classification for height, velocity and explosive strength, due to the delta index of 11.54. We conclude that dermatoglyphics can be a parameter to identify the potentiality of an individual and can be incorporated into a policy of selection and formation of sports talent.

Successful scale-upof the anticancer benzyl isothiocyanate compound production was achieved from cell suspension cultures of Salvadora persica L. Cell cultures were established from the stem internodal segments derived callus. Elicitation with two biotic elicitors; chitosan and salicylic acid, increased callus biomass and benzyl isothiocyanate accumulation, but chitosan induced the maximum accumulation, which reached about four-fold higher over the control at the concentration of 100 mg/L. Benzyl isothiocyanate production from cell suspension cultures was studied in shake-flask culture and stirred-tank bioreactor with the application of the optimum concentration of chitosan in the medium. Both methods elevate the compound production; however its yield was higherin the stirred-tank bioreactor.It achieved about eight-fold increase in the production of benzyl isothiocyanate after 24 days of incubation. This protocol can act as a roadmap for large-scale production of benzyl isothiocyanate from cell suspension cultures ofSalvadora persica by using bioreactors

The present study demonstrates the antioxidative effect of the flavonoid-rich fraction of the methanol extract of Jatropha tanjorensis leaves (FRJT) against CCl4-induced hepatotoxicity in rats. Hepatoprotective and antioxidant properties of FRJT were determined by serum biochemical enzymes; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), antioxidant enzymes (SOD, CAT and GPx), heamatological pararmeters (PCV, Hb and WBC) and histology study. The results obtained showed a significant reduction (p < 0.05) in the activities of liver marker enzymes across the pre-treated groups compared with the untreated rats. Assay of antioxidant enzymes showed that the extract significantly (p < 0.05) enhanced SOD and GPx activities whereas CAT activity was non-significantly (p ˃ 0.05) increased when compared with the untreated animals. PCV, Hb and WBC levels were significantly (p < 0.05) lower in the untreated group. However, supplementation with FRJT and Silymarin ameliorated the induced depletion of blood in the pre-treated animals. Histological examination of the liver tissue showed marked reduction in fatty degeneration across the pre-treated groups when compared with the untreated group. The results in this study indicate that FRJT exhibited varying levels of protection against CCl4-induced oxidative stress in rat models. These results also indicate that the flavonoid-rich fraction contains antioxidants, which mop up free radicals in the system and support its use in the treatment of diseases resulting from oxidative damage.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

I. Introduction
Medicinal herbs are a rich source of antimicrobial agents. A wide range of medicinal plant parts are
used for extract as raw drugs and possess varied medicinal properties.1, 2
Primitive people learned by trial and
error to distinguish useful plants with beneficial effects from those that were toxic or non-active and also which
combinations or processing methods had to be used to gain consistent and optimal results.3
In spite of the great
advances observed in modern medicine in recent decades, plants still make an important contribution to health
care.4
In comparison with modern medicine, herbal medicines cost less, are more often used to treat chronic
diseases and the occurrence of undesirable side effects seems to be less frequent. Contrary to the synthetic
drugs, antimicrobials of plant origin are not associated with side effects and have great therapeutic potential to
heal many infectious diseases.5
Taking into consideration the large potential of plants as sources for
antimicrobial drugs, many systematic investigations were taken into consideration and screened in different
parts of the world.6,7
The importance of the reactive oxygen species (ROS) has attracted increasing attention over the last
decade. Reactive oxygen species include free radicals such as super oxide anion radicals, hydroxyl radicals, non
free radicals such as hydrogen peroxide and singlet oxygen, along with various forms of activated oxygen. They
are involved in various physicochemical processes and disease such as aging, cancer and activity
atherosclerosis.8
The preliminary phytochemical screening carried out in E. alsinoides contains some secondary
metabolites such as glycosides, alkaloids, poly phenols, carbohydrates, amino acids and proteins, saponins,
volatile oil, flavonoids and tannins.9
The plant contains alkaloids such as betaine, shankhapushpine, B-sitosterol
and evolvine. Fresh plant contains volatile oil.
These compounds help brain stimulation and increase the ability to concentrate. Early phytochemical studies of
this species resulted in the isolation and identification of chemical constituents such as triacontane,
pentatriacontane.
Four unidentified alkaloids A, B, C and evolvine have also been described. The present study planned
on Methanolic extract of whole plant of Evolvulus alsinoides for antioxidant potential and Anti microbial
activities, which possess prominent immunomodulatory response and for treating various infectious diseases

II. Materials And Methods
(1) Plant materials and extraction
The plant material was collected from the local rural area of Tumkur district in Karnataka state, India.
The plant materials were identified and authenticated. The Plant material were air-dried and pulverized in course
powder and was loaded in the Soxhlet apparatus for defating with petroleum ether and followed by extraction
with methanol. The methanolic extract of Evolvulus alsinoides was subjected to fractionation and dry
concentrated extract were used for the study
(2) Analytical test for TLC
Alkaloid analyses were done by using the Solvent system: Ethyl acetate: Formic Acid: Acetic Acid:
Water – Ratio 50:5.5:5.5: 13.5, Yellow-Brown colored spots were detected in day-light and UV (256 nm)
Flavonoid analyses were done by using the Solvent system: Chloroform: Methanol- Ratio 42.5: 7.5, Yellow
colored spots in Day-light and UV.
(3) Total Phenolic compounds
The method (Slinkard K,, et al, 1977; Ragazzi and Veronese, 1973) downscaled to 1 mL final volume
was followed to determine the amounts of total phenolics in the test samples. The test samples (each100 / L)
were mixed with 500 /L of 1:10 Folin-Ciocalteau’s reagent followed by the addition of Na2CO3 (400 / L,
7.5%).10, 11
After incubating the reaction mixture at 24 °C for 2 h, the absorbance at 765 nm was recorded. Gallic
acid monohydrate was used as the standard. The total phenolic contents as gallic acid equivalents (μg of
GAE)/mg dry weight of the samples
(4) Total flavanoid content
The determination of the total flavanoid content (TFC) was carried out, briefly, 2.5 ml of each extract
solution was mixed with 2.5 ml AlCl3 reagent in ethanol 90% and allowed to stand for 40 min at room
temperature. After that, the absorbance of the mixture at 415 nm was measured with a SHIMADZU Multispect-
1501 spectrophotometer.12
Ethanol 90% (2.5 ml) plus sample solution (2.5 ml) was used as a blank. Rutin was used as a reference
compound. The TFC for each extract [as μg rutin equivalents (RE) / mg of extract] was determined on the basis
of the linear calibration curve of rutin (absorbance versus rutin concentration)
(5) DPPH free radicals scavenging activity
The free radical scavenging activity of the different fractions of Evolvulus alsinoides was measured
using DPPH, 1 ml of each fraction of Evolvulus alsinoides and the reference compound in various concentration
(50,100, 250 & 500 μg/ml) was added to 1 ml of 0.1mM solution of DPPH in methanol. After 30 min.,
absorbance was measured at 517 nm using spectrophotometer. 0.01 mM solution of DPPH in methanol was
used as control, whereas Quercetin was used as reference material. All tests were performed in triplicate.
Percentage inhibition was calculated by using following formula.13
% Inhibition = control absorbance- test absorbance
Control absorbance
(6) Anti bacterial Activity:
Antibacterial activity of methanolic extract of Evolvulus alsinoides against different test organism was
determined using a modified Kirby-Bauer disc diffusion method.14
Briefly, 100 µl of the test bacteria were grown in 10 ml of fresh media until they reached a count of
approximately 108
cells/ml. 100 µl of the microbial suspension was spread onto nutrient agar plates.

The result of antibacterial activity of methanolic extract of Evolvulus alsinoides against different test organism
have been tabulated in table - 2 and 3.
At a concentration of 512.5mg/ml, the highest zone of clearance was obtained from methanol extract
against Klebsiella pnuemoniae with a diameter of 34mm. This was followed by Salmonella typhi (24mm) and
Escherichia coli (23mm) respectively. The lowest zone of inhibition at this concentration was 5mm against
Staphylococcus aureus.
IV. Discussions
The TLC analysis conducted in this experiment shows the presence of few alkaloids and flavonoids in
the methanolic extract of Evolvulus alsinoides (table -1). This plant is used in Asia, Africa, and Philippines to
cure fever, cough, cold, venereal disease, azoospermia, adenitis, and dementia, nootropic and anti inflammatory
activity reported its use in the treatment neurodegenerative disease asthma and amnesia.15, 16
Pre- clinical
researches has justified its ancient claim’s brain tonic.15
Several other uses reported for this plant include its
ability to boost memory and improve intellect, immunomodulatory, adaptogenetic as well as antioxidant
properties.17
Plant phenolics constitute one of the major groups of compounds responsible for antioxidant
behavior, as well as for antimicrobial effects.

Flavonoids, this diverse and widespread group of natural compounds are the most important natural
phenolics. They possess a broad spectrum of biological activities, including radical scavenging properties and
antibacterial effect (table -1).The study plant E. alsinoides contains alkaloids: betaine, shankhapushpine and
evolvine. Fresh plant contains volatile oil. It also contains a yellow neutral fat, an organic acid and saline
substances.
Scopoletin, scopolin, umbelliferone, 2-methyl-1,2,3,4-Hydrophobic molecules can pass through cell
wall of gram-positive bacteria easier than the gram- negative bacteria because cell wall of the gram- positive
bacteria contained only peptidoglycan (table-2,3).18,19
These results agree with those reported that the
antimicrobial effects of essential oil constituents are dependent on their hydrophobicity.20
V. Conclusion
The results revealed that the methanolic extract of Evolvulus alsinoides are potent antimicrobials against for all
the microorganisms studied, since the plant extracts were rich in Alkaloid and flavonoids, it is indeed possess
potent antioxidant activities
