Chionanthus zeylanica Linn., belongs to the family Oleaceae. The stem bark part of Chionanthus zeylanica Linn., was dried, extracted with different solvents by soxhlet extraction method. Phytochemical studies of all the crude extracts showed the presence of secondary metabolites of flavonoids, steroids, tannins, alkaloids, glycosides, phenols, reducing sugars, etc. The phytochemical results confirm that all extracts contains more important chemical constituents for various biological activities. Antioxidant activity (DPPH) has been carried out for all the crude extracts of Chionanthus zeylanica Linn. The Ethyl acetate and methanol extracts have exhibited significant antioxidant activity in DPPH method. The results indicates that both the extracts firmly posses strong antioxidant effects. Comparatively the Ethyl acetate bark extract showed more antioxidant activity than the methanolic extracts. The results obtained from the present study indicates that the Chionanthus zeylanica Linn., the plant bark extract can be potential source of natural antioxidant activity. This is the first report of antioxidant and phytochemical screening of all the crude extracts of the bark part of this plant
