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...
