Abstract

The roots and aerial parts of Tephrosia major Micheli, afforded a new prenylated-beta-hydroxychalcone, characterized as 2',6'-dihydroxy-3'-prenyl-4'-methoxy-beta-hydroxychalcone. In addition, seven prenylated flavonoids, two rotenoids, beta-sitosterol, stigmasterol, lupeol and quercetin were isolated. The structure of the new beta-hydroxy chalcone was established by spectroscopic methods, including 2D NMR experiments.
