    Abstract:
    Three species of the genus Homalium - e.g. Homalium nepalense, Homalium tomentosum and Homalium zeylanicum (Flacourtiaceae) - are recorded in India which are confined to the Eastern Ghat hill ranges. While H. zeylanicum is the IUCN red-listed medium-sized tree, the other two are endangered species of medicinal significance. The antioxidant potential of leaf and bark of the plants was evaluated through successive extraction methods by using hexane, chloroform, ethyl acetate and methanol. The extracts were subjected to in vitro assays as DPPH, hydroxyl, nitric oxide and superoxide along with its biochemical estimation. Amongst all, the ethyl acetate extracts of bark is found to be most potent compared with that of the leaves. H. nepalense has the highest amount of total phenolic and flavonoid contents followed by H. tomentosum and H. zeylanicum, respectively, and significant antioxidant behaviour.
