From the roots of Caralluma umbellata belonging to the family Asclepiadaceae, a novel pregnane glycoside was isolated. Its structure was elucidated 3-O-?-D-glucopyronosyl, 8?-isopropoxy, 14?-ethynyl, pregn-5en-21,21 dimethy16,17 lactone on the basis of spectroscopic data. This is the first report from the genus Caralluma as well as its family Asclepiadaceae.
