title: Germacranolides from Carpesium lipskyi.
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 ( (1)H- (1)H COSY, (1)H- (1)H NOESY, HMQC, HMBC) and chemical transformations. In addition, two known compounds beta-sitosterol and 7,4'-dimethoxy-5-hydroxylflavanone were also obtained.
