Fig. 1. (a) Scavenging effects of LmEO at different concentrations of 5, 10, 25, 50 and 100 μg mL⁻¹ on the stable 1,1-diphenyl-2-picrylhydrazyl radical (DPPH). Results are expressed as percentage of decrement of absorbance at 517 nm with respect to the control. Ascorbic acid was used as a standard. (b) Antioxidant activities of LmEO at different concentrations of 5, 10, 25, 50, 75 and 50 μg mL⁻¹ measured by the β-carotene bleaching method. Butylhydroxytoluene (BHT) was used as a standard. The results presented are representative of three independent experiments. Values are expressed as mean ± SEM (n = 3).
