Ursane- and oleane-type triterpene glycosides from llex godajam

Abstract

Seven triterpenoid glycosides namely ilekudinoside D (1), kudinoside II (2), mateside (3), suavissimoside R1 (4), 3β-[(α-L-arabinopyranosyl)oxy]-19α-hydro-xyolean-12-en-28-oic acid 28-β-D-glucopyranosyl ester (5), ilexoside XXXI (6). and silphioside B (7) were isolated from a methanol extract of the llex godajam branches and leaves by various chromatographic separations. Their structures were elucidated by extensive analysis of their NMR spectroscopic data as well as comparison of their with those reported. Compounds 1-3 and 5-7 were firstly isolated from I. godajam.
