Chrysanthemum morifolium Ramat. is an important medicinal plant. To learn more about properties of this plant, the present study was aimed to evaluate the phytochemical analysis and antioxidant activity of three colours (pink, yellow and white) flower of Chrysanthemum morifolium. Spot phytochemical screening of these three colours of C. morifolium in the ethanol extract showed that alkaloids, phenols, flavonoids, glycoside and terpenoids were present in studied three colours (pink, white and yellow) flower but saponin and tannin were absent in pink and yellow flower. Free radical-induced oxidative stress is the root cause for many human disease. Naturally occurring antioxidant supplements from plants are vital to counter the oxidative damage in cells. An antioxidant activity of these three flower colours (pink, yellow and white) Chrysanthemum morifolium were examined through DPPH antioxidant assay. The sample showed significant antioxidant activity. Where IC50 value of the three flower extracts were 10.00mg/ml, 11.00mg/ml and 40.00mg/ml for white, pink and yellow flower extracts respectively. In ascorbic acid the IC50 value was calculated 11.50 mg/ml. The phytochemical analysis supports antioxidant properties of these flower colours. So, for comparing among pink, white, yellow flower, white flower of chrysanthemum was found good for potential phytochemical and antioxidant properties than pink and yellow flower.
