Potential Effects of Antioxidant and Serum Cholesterol-Lowering Effects of Gynura bicolor Water Extracts in Syrian Hamster

Figure 1

In vitro antioxidative ability of the GBWE. (a) DPPH radical-scavenging activity, (b) ferrous ion-chelating ability, (c) reducing power, and (d) superoxide radical-scavenging activity. Vitamin C was used as the positive control in the analyses of the DPPH radical-scavenging ability and reducing power, and Na₂EDTA was used as the positive control in the analysis of the chelation of ferrous ions. SOD was used as the positive control in the superoxide radical-scavenging ability assay. The data are expressed as the means ± standard deviations from three independent repeats. Groups with different letters (A, B, and C) are significantly different, as determined by Duncan’s test (). GBWE, G. bicolor water extract.
