Nyctanthes arbortristis is a subcontinental plant of India as well as south Asian part of earth
also known as shiuli in West Bengal belonging to the family Oleaceae[1]. It is having
efficient pharmacological actions in-vivo i.e. inside the body due to presence of different
phytochemicals like Flavonoids, Phenols, Tannins, Alkaloids etc[2]. In this experiment we
have performed the phytochemical screening of leaf extract of N. abortritis followed by
determination of anthelminthic and antioxidant activity.

OBJECTIVE OF WORK
The efficiency of synthetic drugs is becoming less popular due to their adverse
effects and contraindications. It is well to use indigenous natural medicinal plants
which are safe and less expensive also having same or more potency than the
established one.
Here we will try to find the secret treasures those we can get easily from the
plants to make revolution in pharmaceutical field.
The drugs may be with less adverse effects but with high potential to treat
disease.
Here we will examine if Nyctanthes abor-tristis is having any anthelminthic and
antioxidant property or not.
7. METHODOLOGY

Collection and identification of plant:
The fresh leaves of the plant N. arbor-tristis were taken and washed with pure water in the
month of September-October.
Preparation of samples before extraction[6]:
Samples were prepared by washing the leaves with soft and pure water and drying them
under the shade for 5-7 days.
Half-dried leaves were crushed in the grinder and then they were kept for 24 hours
before starting the extraction.
Extraction procedure[6]:
The dried leaves or the coarse powders were taken for extraction in the Soxhlet apparatus.
Extraction was done for 3 days by addition of ethanol as solvent at 40-60 C
After three days the extract was filtered and distillated to get a concentrated product
8. 8
METHODOLOGY
Extraction procedure[6]:
Now the distillated product was taken and dried for 10-15 minutes under a gentle
care.
After this, dry sticky product was kept in the refrigerator for further use.

PHYTOCHEMICAL TEST[7]
10. 10
ANTHELMINTHIC ASSAY[8]
Samples of different concentration (100%; 50% and 25%) of extract solution were
prepared
Standard solution of albendazole was prepared from 400mg of drug
Earthworms are divided into four different groups (each groups containing five
earthworms which were previously washed with saline solution)
Different concentration of samples were given into the petri plates containing
worms
Times for paralysing and time for death of the worms were noted down
Mean paralysing time and death time were determined.
All the results were expressed as mean ± standard error mean (SEM).

OBSERVATION AND RESULT

Calculation of percentage flavonoid content:
Absorbance of the test sample extract solution = 0.401
A = 0.0067 C + 0.0132
Or, 0.0067 C = A – 0.0132
Or, C = (0.401 – 0.0132) / 0.0067
Or, C = 57.89
Therefore,
the concentration of flavonoid present in the extract equivalent to quercetin residue =
57.89 μg/ml
OBSERVATION AND RESULT
19. DISCUSSIONAND CONCLUSION
19
After performing the entire experiment on the leaf extract of plant Nyctanthes arbor-tristis it
can be concluded that therapeutic active phytochemicals like Alkaloid, Flavonoids, Tannins,
Saponins, Glycosides and a small amount of amino acid are present in the extract.
These phytochemicals are responsible for the therapeutic and subtherapeutic activity of shiuli
leaves. In addition, the total flavonoid contain is about 57.89 μg/ml equivalent to the quercetin
residue.
The extract possesses a good anthelminthic property, may be due the synergistic activity of
phytochemicals as compared to the standard drug Albendazole, commonly popular in the
pharmaceutical market.
Beside that the extract is having also antioxidant property that may be used as protectives and
antiaging agent in cosmetic preparation.
We can say that plant Nyctanthes arbor-tristis is enriched in phytochemicals. In near future, if
proper facilities and infrastructure are given, anti-inflammatory and other related
pharmacological activity of the plant extract could be studied.
