Eleven novel pregnane glycosides, 2 – 7 and 9 – 13 , of which four, i.e. , 10 – 13 , comprised a new pregnane‐type genin exhibiting a hydroxymethylene instead of a Me group at C(19), and the known pregnane glycoside stalagmoside V ( 8 ) were isolated from whole plants of Caralluma adscendens var. fimbriata , a native Indian succulent plant. Their structures were elucidated by extensive 2D‐NMR spectroscopic studies.
