Abstract

Eleven pregnanes were isolated from the hydrolysate of the CHCl3 extract fractionated from the caules of Hoya carnosa. Among these, six pregnanes, including 19-acetoxydigipurpurogenin II, were new, and their structures were elucidated. The structures of twenty new pregnane tetraosides and pentaosides, named hoyacarnosides A-T, besides three known ones from the CHCl3 extract, were determined.
