英文摘要	Six new C(21) steroidal glycosides, named curassavosides A-F (3-8), were obtained from the aerial parts of Asclepias curassavica (Asclepiadaceae), along with two known oxypregnanes, 12-O-benzoyldeacylmetaplexigenin (1) and 12-O-benzoylsarcostin (2). By spectroscopic methods, the structures of the six new compounds were determined as 12-O-benzoyldeacylmetaplexigenin 3-O-beta-D-oleandropyranosyl-(1-->4)-beta-D-digitoxopyranoside (3), 12-O-benzoylsarcostin 3-O-beta-D-oleandropyranosyl-(1-->4)-beta-D-digitoxopyranoside (4), sarcostin 3-O-beta-D-oleandropyranosyl-(1-->4)-beta-D-canaropyranosyl-(1-->4)-beta-D-oleandropyranosyl-(1-->4)-beta-D-digitoxopyranoside (5), sarcostin 3-O-beta-D-oleandropyranosyl-(1-->4)-beta-D-canaropyranosyl-(1-->4)-beta-D-canaropyranosyl-(1-->4)-beta-D-digitoxopyranoside (6), 12-O-benzoyldeacylmetaplexigenin 3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-oleandropyranosyl-(1-->4)-beta-D-canaropyranosyl-(1-->4)-beta-D-oleandropyranosyl-(1-->4)-beta-D-digitoxopyrano side (7), and 12-O-benzoylsarcostin 3-O-beta-D-glucopyranosyl-(1-->4)-beta-D-oleandropyranosyl(1-->4)-beta-D-canaropyranosyl-(1-->4)-beta-D-oleandropyranosyl-(1-->4)-beta-D-digitoxopyranoside (8), respectively. All compounds (1-8) were tested for in vitro cytotoxicity; only compound 3 showed weak inhibitory activity against Raji and AGZY cell lines. (C) 2008 Elsevier Inc. All rights reserved.
