title: Six new cycloartane triterpene glycosides from Actaea asiatica.
abstract: Six new cycloartane triterpene glycosides, (3',12beta)-O-diacetyl-cimigenol-3-O-beta-D-xylopyranoside (1), (4',25)-O-diacetyl-cimigenol-3-O-beta-D-xylopyranoside (2), 2'-O-acetyl-25-O-methyl-cimigenol-3-O-beta-D-xylopyranoside (3), 2'-O-acetyl-25-O-ethyl-cimigenol-3-O-beta-D-xylopyranoside (4), 3'-O-acetyl-cimicifugoside (5), and 4'-O-acetyl-23-epi-26-deoxycimifugoside (6), were isolated from the rhizomes of Actaea asiatica. Their structures were elucidated on the basis of chemical methods and spectroscopic analysis. Compounds 1, 2, 4-6 exhibited positive cytotoxic activities.
