Studies on the Constituents of Compositae Plants. Part II. Oleanane Glycosides from Eclipta alba.
摘要:
From the whole parts of Eclipta alba HASSK., six new oleanane triterpene glycosides, named eclalbasaponins I-VI (1-6), were isolated. The structures of 1-6 were characterized as echinocystic acid glycosides, and of those, 5 and 6 were revealed to be sulfated saponins on the basis of chemical and spectral data.
