title: Germacranolides and their diversity of Eupatorium heterophyllum collected in P. R. China.
abstract: Eight new hydroperoxides and a new enone of germacrane-type sesquiterpenoids were isolated from the aerial parts of eight different samples of Eupatorium heterophyllum DC. (Asteraceae) collected in P. R. China. The structures were determined based on spectroscopic analyses. Seven of the eight samples produced hiyodorilactone A as a major constituent, while one afforded neither hiyodorilactone nor hydroperoxide. The results indicated the presence of diversity within this species.
