Two new triterpenoid saponins, ilemaminosides A and B (1 and 2) along with six known saponins (3-8) were isolated from 70% ethanolic extract of the leaves of Ilex mamillata C.Y. Wu ex C.J. Tseng. The new saponins were characterised as 3-O -α- L-arabinopyranosyl-ilexgenin B (1) and 3-O-β-D- glucopyranosyl-(1→3) -α-L-arabinopyranosyl-ilexgenin B (2). The structures of compounds 1 and 2 were elucidated on the basis of the chemical and spectroscopic methods, and the structures of known compounds were identified by comparison of their spectroscopic data with those reported in the literature. The compounds showed inhibitory activities in anti-inflammatory assay invitro with IC50 values in the range 25.37-38.33gmL1.

Three new triterpenoid saponins, latifolosides F, G, H were isolated from the leaves of Ilex latifolia. Their structures were elucidated on the basis of chemical and spectral evidence. Latifoloside F was determined to be 3-O-[α-L-rhamnopyranosyl(1-2)]-[β-D-glucopyranosyl(1-3)-]-α-L- arabinopyranosyl ilexgenin B 28-O-[α-L-rhamnopyranosyl(1-2)]-β-D- glucopyranoside. Latifoloside G was 3-O-[α-L-rhamnopyranosyl(1-2)]-[β-D- glucopyranosyl(1-3)-]-α-L-arabinopyranosyl pomolic acid 28-O-[α-L- rhamnopyranosyl(1-2)]-β-D-glucopyranoside. Latifolioside H(3) was 3-O-[α- L-rhamnopyranosyl(1-2)]-[β-D-glucopyranosyl(1-3)-]-α-L-arabinopyranosyl siaresinolic acid 28-O-[α-L-rhamnopyranosyl(1-2)]-β-D-glucopyranoside.
