Seven triterpenoid glycosides namely ilekudinoside D ( 1 ), kudinoside H ( 2 ), mateside ( 3 ), suavissimoside R1 ( 4 ), 3 β ‐[( α ‐L‐arabinopyranosyl)oxy]‐19 α ‐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 Ilex 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 them with those reported. Compounds 1 ‐ 3 and 5 ‐ 7 were firstly isolated from I. godajam .
