摘要
A new skeleton bisabolane-type sesquiterpene curcuminoid,bisabocurcumin（1）,along with 5 known compounds,curcumin（2）, demethoxycurcumin（3）,bidemethoxycurcumin（4）,（1E,4E）-1,5-bis（4-hydroxy-3-methoxyphenyl）-penta-1,4-dien-3-one（5）,and （1E,4E）-1-（4-hydroxy-3-methoxyphenyl）-5-（4-hydroxy phenyl-）-penta-1,4-dien-3-one（6）were isolated from the rhizomes of Curcuma longa L.Their structures were determined on the basis of spectroscopic analysis.Bisabocurcumin（1） is firstly obtained from nature with a new skeleton combined by a bisabolane-type sesquiterpene and a 1,7-diphenylheptanoid through a C-C bond.
