Fig. 2. ABTS radical scavenging activity of Nypa fruticans wurmb extract. ABTS radical scavenging analysis was performed to investigate. The antioxidant effects of Nypa fruticans wurmb at varying concentration levels of 125 μg/mL, 250 μg/mL, 500 μg/mL, 1,000 μg/mL. The appropriate amount of ascorbic acid was used as a positive control (AA). Each value presents the mean ± standard deviation (n=3). Asterisks indicate a significant increment in ABTS scavenging activity compared with controls (*P<0.05, **P<0.01).
