【 摘 要 】

Antioxidant activity of the extract from the barks ofIlex rotundawas investigated using electron spin resonance (ESR) spectroscopy on 1,1-diphenyl-2-picrylhydrazyl (DPPH), alkyl, hydroxyl, and superoxide radicals. The extract exhibited strong free radical scavenging activity with scavenging percentages of DPPH radical (82.2 ± 1.8%), alkyl radical (82.9 ± 1.7%), hydroxyl radical (89.9 ± 2.1%), and superoxide radical (92.5 ± 2.6%) at concentration of 50 μg/ml, respectively. Activity increased with increasing extract concentrations. Therefore, these results presented the extract from the barks ofI. rotundawith a potent antioxidant activity that could be useful in food, pharmaceutical, and cosmetic industries.
