AbstractSix new triterpene glucosides, quadranosides VI-XI (1-6), belonging to three different [ursane- (1-4), oleanane- (5) and lupane-type (6)] triterpene classes, have been isolated from a MeOH extract of the seeds of Combretum quadrangulare KURZ (Combretaceae), together with nine known compounds, rosamutin (7), 28-O-β-D-glucopyranosyl-6β, 23-dihydroxytormentic acid (8), arjunetin (9), arjunglucoside II (10), combreglucoside (11), chebuloside II (12), vitexin (13), (+)-catechin (14) and (-)-epigallocatechin (15). The structures of these compounds were elucidated by spectroscopic analysis.
