Clinoposaponins I-V, new oleanane-triterpene saponins from Clinopodium gracile O. Kuntze.
From the whole plants of Clinopodium gracile five new saponins, called clinoposaponins I-V, were isolated together with two known and four artifact saponins, and their structures elucidated from spectroscopic data and chemical evidence. These saponins were composed of saikosaponin a and additional glucose moieties.
