نبذة مختصرة : The edible parts of Brassica plants are a rich source of phytochemical compounds which possess strong antioxidant potential. These plants contain a variety of phytochemical compound including phenolics, polyphenols, phenolic acids, flavonoids, carotenoids (zeaxanthin, lutein, β-carotene), alkaloids, phytosterols chlorophyll, glucosinolates, terpenoids, and glycosides. These plants possess strong antioxidant potential in terms of metal reducing, metal chelating, lipid reducing and free radical scavenging activities. These also have a positive effect on the activity of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase, and ascorbate peroxidase. Among various species of genus Brassica studied for their phytochemical composition and antioxidant activity, Brassica oleracea leaves, florets and seeds have better phytochemical and antioxidant profile. Brassica juncea, Brassica napus, Brassica rapa and Brassica nigra are also the phytochemical and antioxidant rich species of genus Brassica. The phytochemical profile and antioxidant potential of Brassica plants make them the preferable candidates for nutritional and pharmaceutical applications.
