				        	Object  To study the chemical constituent and the bioactivity in the bark of Tsoongiodendron odorum Chun   Methods  By bioactive following method, the extracts of both EtOAc and n  BuOH in the bark of T   odorum were screened for in vitro anti  tumor activity    Results  Five constituents were obtained   Among them, three from EtOAc fraction belonged to germacranolides   They were costunolide (Ⅰ), parthenolide (Ⅱ) and dihydroparthenolide (Ⅲ)   The other two were from the fraction of n  BuOH, one was an oxoaporphinoid alkaloid, liriodenine (Ⅳ), and the last was a furanone, 2, 3  dihydroxyl  2  methyl  butylrolactone (Ⅴ)   Conclusion  All the above five compounds are found for the first time from this plant   Compounds Ⅰ, Ⅱ, Ⅳ, and Ⅴ show the cytotoxic activities against a variety of tumor cell strains, respectively
