2. INTRODUCTION
THE ANTIBACTERIAL ACTIVITY OF MANY DRUGS IS PROGRESSIVELY
DECREASING AS THE MICROBES ARE DEVELOPING RESISTANCE TO
THE DRUGS.
THE QUEST FOR NEWER ANTIBACTERIAL WITH EFFICIENT
ANTIBACTERIAL ACTIVITY IS GOING ON.
IN ANCIENT TIMES, PASSIFLORA FOETIDA WAS EMPLOYED IN
TRADITIONAL MEDICINE FOR VARIOUS THERAPEUTIC ACTIONS.
PASSIFLORA FOETIDA WAS SELECTED FOR ANTIBACTERIAL
TESTING IN HOPE OF DEVELOPING A NEW ANTIBACTERIAL DRUG.

3. Aim and scope of the work
• THE AIM OF STUDY WAS TO EVALUATE THE
ANTIBACTERIAL ACTIVITY OF ETHANOLIC
EXTRACTS OF LEAF & ROOT OF PASSIFLORA
FOETIDA

4. PASSIFLORA FOETIDA - PROFILE
PASSIFLORA FOETIDA WIDELY DISTRIBUTED PLANT IN INDIA
BELONGS TO FAMILY : PASSIFLORACEAE
 SYNONYM : WILD WATERMELON
TRADITIONALLY USED AS : ANTI-DIABETIC,
ANTI-INFLAMMATORY
ANALGESIC.
COLLECTION OF PLANTS AND LEAVES WAS DONE IN AND AROUND
ONGOLE.

5. EXTRACTION
 METHOD OF EXTRACTION :
CONTINUOUS HOT PERCOLATION
 APPARATUS EMPLOYED :
SOXHLET APPARATUS
 PLANT PART EXTRACTED :
LEAVES AND ROOTS
 SOLVENTS USED :
ETHANOL (95%)

6. EVALUATION OF ANTIBACTERIAL ACTIVITY
METHODOLOGY
Medium : Mueller-Hinton Agar Medium (Himedia)
Method : Cup plate method
Standard drug : Tetracyclin (30 µg/100 µl)
Kannamycin (30 µg/100 µl)
Incubation : 37 oC for 24-48 hrs.
Micro-organisms used
E.Coli Bacillus subtilis pseudomonas staphylococcus . Klebsiella pneumoniae
putida pyogenes

7. EXTRACTS OF PASSIFLORA FOETIDA L LEAVES AND ROOT
DILUTIONS FOR PRODUCT A(LEAF EXTRACT) &
PRODUCT B(ROOT EXTRACT)
250µg/100µl
500µg/100µl
750µg/100µl
1000µg/100µl
Incubation :
The inoculated plates were incubated at 37ºC for 24 - 48 hrs.
After incubation, the zone of inhibitions were measured

8. ANTIBACTERIAL ACTIVITY
Zone of inhibitions{in mm}
From the above data ,Product A(Leaf extract) shows BETTER
zone of inhibition when compared against Product B(Root
extract),and standards Tetracyclin,Kanamycin

11. CONCLUSION
THE ABOVE RESULT WAS COMPARED WITH ZONE OF INHIBITION PRODUCE BY
STANDARD ANTIBIOTICS LIKE TETRACYCLIN (30ΜG) - 25 MM AND KANAMYCIN
(30ΜG)- 18 MM. IT CLEARLY SHOWS THAT THE ISOLATED COMPONENTS OF
PASSIFLOREA FOETIDA ARE IN PROGRESS AS POTENT AGENTS AGAINST BOTH
GRAM POSITIVE AND GRAM NEGATIVE MICROBES.
THE SCREENING OF PASSIFLORA FOETIDA L REVEALED
PROMISING ANTI-BACTERIAL PROPERTIES.
PASSIFLORA FOETIDA L CAN BE FURTHER RESEARCHED FOR
ANTI-BACTERIAL STUDIES.
