ELAEOCARPUS FLORIBUNDUS SP. FROM WEST BENGAL: IN VITRO ANTIMICROBIAL AND ANTIOXIDANT PROFILING

Abstract

Indian olive, or Elaeocarpus floribundus Blume, is a medicinal as well as a traditional plant whose parts have long been used to cure a variety of ailments, including rheumatism, ulcers, and inflammatory gums. It is also used as a mouthwash. The leaves were extracted using soxhlet assembly by using petroleum ether, chloroform and ethanol serially. The several investigations were done on the fruits of this species E. floribundus as Indian olive but very few studies were done on the leaves and their extracts. Antioxidant potential of ethanolic extract was assessed by DPPH methods and ethanolic extract showed stronger antioxidant potential in DPPH test (IC₅₀ 33.28%). The antimicrobial activity was examined against the strains like Escherichia coli and Candida albicans. An antimicrobial activity tested against E. coli strain shows the no zone of inhibition at all concentrations and against C. albicans shows high activity with a diameter inhibition of 16.125 mm and at the lowest concentration 200 μg/mL shows no inhibition zone.
