摘      要：Objective:To evaluate the antioxidant potential of methanolic leaf extract of Indigofera cassioides(MEIC) using various in vilro antioxidant assay ***:Antioxidant and free radical scavenging activity of MEIC was assayed by using different in vitro models like ABTS, DPPH,nitric oxide,superoxide,hydrogen peroxide and hydroxyl *** ability of the extract was tested by the complex formation with potassium *** total phenol and flavonoid contents of the crude extract were also *** and ascorbic acid were used as ***:MEIC exhibited potent and concentration dependent free radical scavenging activity in all the tested *** ability was also found to increase with increase in MEIC *** phenol and flavonoid content determination showed that the extract is rich in phenols and ***:All the results of the in vitro antioxidant assays reveal potent antioxidant and free radical scavenging activity of the leaves of Indigofera cassioides,equivalent to that of standard ascorbic acid and *** potent antioxidant activity may be attributed to its high phenolic and flavonoid contents.
