Two new triterpenoid glycosides were isolated (one of them as the methyl ester) as major components from leaves of Ilex chinensis SIMS (Aquifoliaceae). The structures of these glycosides, termed ilexoside A (1) and ilexoside B methyl ester (2a), have been established to be 3β-Ο (β-D-xylopyranosyl) siaresinolic acid and 3β-Ο (β-D-xylopyranosyl) pomolic acid methyl ester, respectively, based on chemical and spectral evidence. High-resolution 13C-nuclear magnetic resonance data for the methyl ester of 1 (1a) and 2a are also reported.
