Two new germacranolides, carpelipine A and carpelipine B in the form of its pyrazoline derivative were isolated from the whole plants of Carpesium lipskyi, and their structures were elucidated by spectroscopic methods including 2D NMR techniques (H-1-H-1 COSY,H-1-H-1 NOESY, HMQC, HMBC) and chemical transformations. In addition, two known compounds beta-sitosterol and 7,4'-dimethoxy-5-hydroxylflavanone were also obtained.
