摘要：

The structure of a piscicidal triterpenoid saponin (saponin A) isolated from the leaves of Maesa ramentacea has been shown to be 3-O-{[(alpha-L-rhamnopyranosyl(1-->2)-alpha-L-rhamnopyranosyl(1-->2)-beta-D-galactopyranosyl 1-->3)]-[beta-D-glucopyranosyl(1-->2)]-beta-D-glucuronopyranosyl}barringtogenol C21, 22-O-diangeloate. Extensive use was made of homo- and heteronuclear 2D NMR techniques. Copyright (C) 1997 Elsevier Science Ltd
