Two new polyhydroxypregnane glycosides, namely cynotophyllosides I-J, were isolated from the roots of Cynanchum otophyllum, together with three known steroids, namely deacetylmetaplexigenin, sarcostin and hemoside. Their structures were established by ext

Two new oxypregnane-oligoglycosides named calotroposides A (1) and B (2) have been isolated from the root of Calotropis gigantea (Asclepiadaceae), an Indonesian medicinal plant, and their chemical structures have been elucidated by chemical and spectroscopic methods as 12-O-benzoyllineolon 3-O-β-D-cymaropyranosyl(1→4)-β-D-oleandropyranosyl(1→4)-β-D-olean dropyranosyl(1→4)-β-D-cymaropyranosyl(1→4)-β-D-cymaropyranoside and 12-O-benzoyldeacetylmetaplexigenin 3-O-β-D-cymaropyranosyl(1→4)-β-D-oleandropyranosyl(1→4)-β-D-olean dropyranosyl(1→4)-β-D-cymaropyranosyl(1→4)-β-D-cymaropyranoside, respectively.

Seven new glycosides named wilfosides D1N (7), K1N (8), M1N (9), F1N (10), W1N (11), W3N (12), and G1G (13) were isolated from Cynanchum wilfordi HEMSLEY (Asclepiadaceae), and their structures were deduced on the basis of spectral and chemical evidence.A
