A Bis-Bithiophene from Tridax Procumbens L. (Asteraceae)
2002
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.
