From the rhizome of Anemarrhena asphodeloides BUNGE (Liliaceae), four new steroidal saponins named anemarrhenasaponins I-IV (1-4) were isolated, together with known saponins, timosaponin A-III (5), marcogenin diglycoside (6) and timosaponin B-II (7) and a xanthone C-glycoside, mangiferin. These saponins are coprostane type steroidal glycosides. Their structures were established on the basis of spectroscopic and chemical evidence.
