Abstract

Phytochemical study on the leaves of Ficus religiosa led to the isolation of three lignans. Their chemical structures were determined to be (+)-pinoresinol (1), pinoresinol di-0- β-Dglucopyranoside (2) and syringaresinol 0-β-D-glucopyranoside (3) hy means of spectroscopic studies including NMR and ESI mass spectra. The antioxidant activities of these compounds were screened using DPPH system. Among them, compounds 1 and 3 exhibited significant scavengingactivines with EC50 values of 16.90 and 16.93 µM, respectively
