摘要

原甘松己烷萃取物的乙酸乙酯可溶部分与四种已知的萜类化合物:乙酸taraxasteryl、g -amyrenone、luppeol和齐墩果酸一起合成了一种新的双双噻吩,命名为tridbibi噻吩。通过1 D-NMR对分离得到的化合物进行了结构鉴定,通过COSY和HMBC相互作用对新化合物三双噻吩进行了结构鉴定。

A Bis-Bithiophene from Tridax Procumbens L. (Asteraceae)
The ethyl acetate soluble part of hexane extract of Tridax procumbens yielded a new bis-bithiophene named tridbisbithiophene along with four known terpenoids: taraxasteryl acetate, g -amyrenone, lupeol and oleanolic acid, which have never been reported so far from Tridax procumbens . The structures of all the isolated constituents were elucidated with the aid of 1 D-NMR spectroscopy whereas, the structure of new constituent tridbisbithiophene was confirmed via COSY and HMBC interactions.
