Studies on the Constituents of Solanaceous Plants. (46). Steroidal Glycosides from the Fruits of Solanum anguivi.

Abstract

Three new glycosides named anguiviosides A-C were isolated from the fruits of Solanum anguivi and characterized as follows:3-O-beta-chacotrioside (1), 3-O-[4-O-maloyl-alpha-L-rhamnopyranosyl(1-->2)]-alpha-L-rhamnopyra nosyl(1-->4)-beta-D-glucopyranoside (2) and 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D-xylopyranosyl(1-->3)]-beta-D-+ ++glucopyranoide (3), of (25R,26R)-spirost-5-en-3beta,26-diol.
