EVALUATION OF PHYTOCHEMICALS, REDUCING POWER, ANTIOXIDANT ACTIVITY AND IN-VITRO LIPID PEROXIDATION ACTIVITY OF WHEAT GRASS JUICEAbstract
Oxidative stress is a condition due to excessive production of free radicals than the ability of the antioxidant system to counteract them. Antioxidants scavenge and suppress the deleterious effects of free radicals. Both exogenous and endogenous sources of antioxidants are important in pathological conditions. Exogenous antioxidants include dietary sources and even include medicinal plants. These medicinal plants contain phytochemicals which contribute to the beneficial antioxidant activity. Wheat germinated over a period of 9-10 days is generally called wheat grass. The purpose of this work is to determine the phenolic, flavonoids, flavonols and total alkaloids from wheat grass juice. Free radical scavenging activity of wheat grass juice was evaluated by using DPPH , nitric oxide, hydroxyl radical and total antioxidant power by FRAP assay and antilipidperoxidation activity by using mice liver and brain. Wheat grass juice is found to have good antioxidant action in various models due to its polyphenols and phytochemicals.
