ISSN 0189-6016©2007 ISOLATION OF A STILBENE GLYCOSIDE AND OTHER CONSTITUENTS OF TERMINALIA

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
