Fig. 3From: HPLC-DAD analysis of Hyssopus Cuspidatus Boriss extract and mensuration of its antioxygenation propertyFree radical scavenging capacity of VC and ethanol extract of H. cuspidatus in different years. (a represents DPPH free radical scavenging capacity. b represents ABTS free radical scavenging capacity. c represents Hydroxyl free radical scavenging capacity. d represents Superoxide free radical scavenging capacity. Values were means ±SD of three replications. * represents the values of different group are significantly different from each other (P < 0.01))Back to article page
