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