Abstract

A flavonoidal glycoside, named flavon-5, 3’, 4’-trihydroxy 7-O-β-D-glucopyranosyl (6’’→1’’’) β-D-glucopyranoside, has been isolated from the stem bark of Quercus leucotrichophora, together with β-sitosterol, kaempferol, quercetin and 7-methoxy kaempferol. The structure of flavon-5, 3’, 4’-trihydroxy 7-O-β-D-glucopyranosyl (6’’→1’’’) β-D-glucopyranoside, by means of rigorous spectroscopic analysis including 2-D NMR measurements.
