Antioxidant and Immunomodulatory Activity of Hydroalcoholic Extract and its Fractions of Leaves of Ficus benghalensis Linn.

BACKGROUND

Ficus benghalensis is a folk medicine indigenous plant of India. Several studies on this plant reported and focused on the biological profile of the plant.

OBJECTIVE

This study is aimed to evaluate the antioxidant and immunomodulatory activity of F. benghalensis leaf extract using various in vitro screening methods of both parameters.

METHODS

Hydroalcoholic (FB1) extract and it's four fractions viz. n-hexane (FB2), n-butanol (FB3), chloroform (FB4), and water (FB5) of leaves of F. benghalensis investigated for their free radical scavenging activity using 1-1-diphneyl-2-picrylhydrazyl and 2, 2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) radicals. A dose-response curve was plotted and IC50 values were determined to assess antioxidant activity. Nitroblue tetrazolium test, phagocytosis of killed Candida albicans and candidacidal assay were carried out to assess the immunomodulatory activity. Positive non-lymphoid cell number, mean particle number of killed C. albicans, percent value of killed C. albicans by neutrophils were calculated and presented.

RESULTS

All extracts showed antioxidant and prominent immunomodulatory activity with compared to standard.

CONCLUSIONS

Hydroalcoholic (FB1) extract and its four fractions viz. n-hexane (FB2), n-butanol (FB3), chloroform (FB4), and water (FB5) showed promising antioxidant and immunomodulatory activity.

CONCLUSIONS

Hydroalcoholic extract and its fractions of F. benghalensis Linn exhibited different DPPH and ABTS scavenging activity in concentration dependent manner.The extract, fractions and reference antioxidants showed DPPH scavenging effect in the order of Vit-C > Quercetin > FB2 > FB1 > FB5 > FB4> FB3 and ABTS scavenging effect in the order of Vit-C > Quercetin > FB1> FB2 > FB5 > FB3> FB4.FB2 and FB3 showed promising immunomodulatory activity at all concentrations.
