Eleven new triterpenoid saponins, scabiosaponins A-K (1-11), and hookerosides A (12) and B (13) were isolated from the whole plants of Scabiosa tschiliensis. The structures of the new compounds were established on the basis of extensive NMR (DEPT, DQF-COSY, HETCOR, TOCSY, HMQC, HMQC-TOCSY, HMBC, and NOESY) and MS studies coupled with chemical degradations. The biological activity of compounds 1-10, 12, and 13 and prosapogenin 1b were examined against pancreatic lipase. Scabiosaponins E, F, G, I (5, 6, 7, 9), hookerosides A, B (12, 13), and prosapogenin 1b all exhibited strong inhibition of pancreatic lipase in vitro.

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.
