Abstract : The study on antibacterial and antifungal efficacy of leaf and seed extract and seed oil of Jatropha curcas reveals that the inhibition zones ranged from 7 to 22 mm for antibacterial and from 10 to 20 mm for antifungal activity. Among all extracts tested, seed extract showed significant activity while leaf extract showed intermediate activity against gram-positive bacteria. In case of gram-negative bacteria, seed extract and seed oil has shown some moderate activity whereas, no activity was observed in leaf extract. In case of fungal cultures, among all test extracts only seed extract showed significant activity against Mucor and Tilletia fungus, while in case of Rhizopus no activity was observed against all test extracts. These results indicated the possibility of using Jatropha extract and seed oil for medicinal uses and natural food preservation.
