Abstract

Abstract Phytochemical investigation on the seeds of Oroxylum indicum (L.) Vent. led to the isolation of two new stilbenoid compounds (E)-dihydropinosylvin-2-carboxyl-5-O-β-d-glucopyranoside (1) and (E)-dihydropinosylvin-3-O-β-d-glucopyranoside (2), along with the three known compounds, (E)-pinosylvin-3-O-β-d-glucopyranoside (3), dihydropinosylvin (4) and pinosylvin (5). Their structures were elucidated by spectroscopic techniques. The stilbenoids identified in the seeds of O. indicum may possess chemotaxonomic significance at the generic level.
