a Dose dependent DPPH radical scavenging activity. Ascorbic acid and Gallic acid used as a standard reference. b Hydroxyl radical scavenging activity. Butylated hydroxytoluene (BHT) and gallic acid. c Dose dependent inhibition of RNS derived from nitric oxide by isolated compounds (C1C3) in comparison with standard reference Rutin. d Dose dependent increase in total antioxidant capacity (TAC) of isolated compounds. Gallic acid used as standard reference. Values are expressed as mean ± SEM (n = 3). C1: 7-O-galloyl catechins, C2: catechins and C3: methyl gallate (C3)
