title: Mazusaponins I-IV, triterpene saponins from Mazus miquelii.
abstract: From whole plants of Mazus miquelii, four new saponins designated as mazusaponins I-IV and a known saponin, ilexoside VIII, were isolated and the structures of the new compounds elucidated as 3-O-alpha-L-arabinopyranosyl siaresinolic acid 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, 3-O-alpha-L-arabinopyranosyl pomolic acid 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, 3-O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranosyl siaresinolic acid 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester and 3-O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranosyl pomolic acid 28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester, respectively, by spectroscopic data and chemical evidence.
