title: Constituents of Afzelia bella stem bark.
abstract: The stembark of Afzelia bella yielded an acylated dihydroflavonol glycoside identified as 2R,3R-trans-aromadendrin-7-O-beta-D-glucopyranoside-6''-(4''-hydroxy-2''-methylene butanoate), along with five known flavonoids and the lignan glycoside (+)-isolariciresinol 9-O-xyloside. Their structures were determined by detailed 1D and 2D NMR analyses.
