PHYTOCHEMICAL STUDIES AND ANTIOXIDANT ACTIVITIES OF BRASSICA OLERACEA L.VAR.CAPITATA Research Article

The aim of this study was to investigate the antioxidant activities and phytochemical analysis of Brassica oleracea L. var. capitata. The phytochemical screening was carried on the leaves extracts of Brassica oleracea L. var. capitata revealed the presence of some active ingredients such as Alkaloids, Tannins, Saponins, Phenols, Glycosides, Steroids, Terpenoids and Flavonoids. The ethanol leaves extract were also evaluated for their total phenolic contents and antioxidant activity using DPPH radical scavenging assay and reducing power assay. The result of the present study showed that the ethanolic leaves extract of Brassica oleracea L. var. capitata which contains highest amount of phenolic compounds exhibited the greatest anti-oxidant activity than Petroleum Ether, ethylacetate, chloroform and aqueous extracts. The high scavenging property of may be due to hydroxyl groups existing in the phenolic compounds.
