Abstract :
This study aimed to the discovery of new biologically active natural products with hormone- like activity from Butea frondosa Roxb., Family Leguminosae growing in Egypt. The investigation of estrogen- like activity showed that both the successive non-polar and methanolic extracts showed a significant estrogen-like activity in immature female rats. GLC analysis the non-polar bioactive revealed the presence of eicosane (22.5%) and β-amyrin (20.5%) as the major components in the unsaponifiable matter, while palmitic (24.9%) and linoleic (36.8%) acids were the main saturated and unsaturated fatty acids. The successive bioactive methanolic extract was subjected to chromatographic separation to yield five flavonoids identified as vicenin II, vitexin, chrysoeriol 7-o-β-D-glucuronic acid, 6,8-di-C-rhamnosyl apigenin and luteolin.
