ABSTRACT

The present study was carried out to determine the antioxidant activity in the Acacia nilotica, Solidago virgaurea, Coriandrum sativum, Murrya koenigii, Azadirachta indica, Spinacia oleracea, Ocimum tenuiflorum, Trigonella foenum, Saraca asoca and Aloe barbadensis medicinal plants. Out of ten plant samples tested, leaf extract of Solidago virugaurca was found to have maximum percent inhibition value of 130% for free radical scavenging capacity and Aloe barbadensis was found to have maximum superoxide anion radical scavenging activity (78.5%). Hydroxyl radical activity was found to be maximum for Corriandrum sativum (117%). Also, Hydrogen peroxide activity for Murraya konengii was found to be maximum at 900%. Reducing power capacity of Azadirachta indica was found to be 11.1 mg/ml and Nitric Oxide activity for Solidago virgaurea and Spinacia oleracea possessing highest activity (12.2 mg/ml). It can be inferred that the parts of plant having high content of phytochemicals may serve as a good source of nutraceuticals which have potential for use in health care formulations.
