Primary sources of naturally occurring antioxidants are whole grains, fruits and vegetables. Most of the antioxidant compounds in a typical diet are derived from plant sources and different variety of physical and chemical properties. Butea monosperma is silviculturally important, as it is one of the commonest on the plains of India and capable of thriving where most species will not grow. The leaves of Butea monosperma plant are credited with astringent, tonic, diuretic, and aphrodisiac properties. They are used to cure boils, pimples and tumerous hemorrhoids and are internally given in flatulent colic, worms and piles. The leaves are reported to contain alkaloids, protein, fiber and minerals. In the present study fresh leaves of Butea monosperma plant were isolated for various ingredients i.e., terpenoids and phenolics, fats and waxes, alkaloids, quaternary alkaloids and N-oxides and screened for their antioxidant activity.
