Abstract
A new triterpene glycoside, rollentoside A, has been isolated from Asterias rollentoni Bell and identified as 3beta-O-{3-O-methyl-beta-D-xylopyranosyl-(1-->3)-O-beta-D-glucopyranosyl-(1-->4)-O-beta-D-quinopyranosyl-(1-->2)-O-beta-D-xylopyranosyl}-16-beta-acetoxy-23S-acetoxy-holost-7-ene (1), together with a new natural product, rollentoside B (2). The structures of compounds1 and 2 were elucidated by extensive 1D and 2D NMR investigation (1H-1H COSY, TOCSY, HSQC, HMBC, NOESY).Entities:
