Abstract

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 (1H-1H COSY, 1H-1H NOESY, HMQC, HMBC) and chemical transformations. In addition, two known compounds β-sitosterol and 7,4′-dimethoxy-5-hydroxylflavanone were also obtained.
