Abstract

The roots of Terminalia alata yielded three new glycosides: 3,3'-di-O-methylellagic acid 4-O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->2)-alpha-L-arabinopyranoside (1), 5,7,2'-tri-O-methylflavanone 4'-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranoside (2), and 2alpha,3beta, 19beta,23-tetrahydroxyolean-12-en-28-oic acid 3-O-beta-D-galactopyranosyl-(1-->3)-beta-D-glucopyranoside-28-O-beta-D-glucopyranoside (3). Compounds 2 and 3 displayed antifungal activity.
