ABSTRACT: The main objective of the investigation has been to evaluate the extracts of common Kashmiri Haakh (local collard greens, identified as Brassica olerecea var Haka Javied) for antioxidant activities. A battery of locally improvised in vitro inexpensive methods have been employed to confirm the antioxidant potential of the vegetable most widely consumed in the Kashmir valley. The activity of the extracts has ranged from marked reduction towards ions of permanganate, iodine, iron (III), dichromate and MTT to remarkable scavenging activity towards reactive oxygen species including peroxide ions, hydroxyl radicals (Fenton reaction), nitrous acid / nitric oxide and superoxide anions generated from alkaline pyrogallol and alkaline hydroxylamine. Phytochemical analysis has revealed presence of phenolics and flavonoids in alkaline hydroalcoholic extract, beta-carotene in chloroform-petroleum ether extract and thiocyanate in water-soluble extract obtained from organic solvent soluble extract. The work confirms obvious potential advantages of the vegetable for the local population.
