Isolation of a stilbene glycoside and other constituents of terminalia sericeae

Abstract

The ethanol extract of the root bark of Terminalia sericea yielded an unreported stilbene glycoside, 3′5′-dihydroxy-4-(2-hydroxy-ethoxy) resveratrol-3-O-β-rutinoside (1) together with known compounds resveratrol-3-β-rutinoside glycoside (2), 3′,4,5′-Trihydroxystilbene (resveratrol) (3), triterpenoic acid arjungenin and a mixture of β-sitosterol and stigmasterol. Structure determination of the isolated compounds was achieved on the basis of spectroscopic measurements. © 2007.
