Indonesian medicinal plants. I. Chemical structures of calotroposides A and B, two new oxypregnane-oligoglycosides from the root of Calotropis gigantea (Asclepiadaceae)

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.

Expeditious synthesis of saponin P57, an appetite suppressant from Hoodia plants

Pregnane glycoside P57, the appetite suppressant component from Hoodia, was synthesized expeditiously, featuring preparation of the aglycone Hoodigogenin A from digoxin and assembly of the deoxytrisaccharide with glycosyl o-alkynylbenzoates as donors.
