Abstract

Two flavonoids. (-)-epicatechin ('1) and quercetinS-O-fi-D-galactopyranoside (2), and one prenylbenzoic acid derivative, 4-O-β-D-glucopyranosyl-3-preny!benzoic acid (3), were isolated from the aerial parts of Sarcosperma affinis Gagnep.. Their chemical structures were determined on the basis of spectroscopic analyses in reference to the literary. These compounds were obtained from Sarcosperma genus for the first time.
