摘　　要：采用DPPH自由基清除法、还原能力评价法两种体外抗氧化活性试验对香樟枝6种不同极性提取物进行了抗氧化活性研究。研究结果表明,在一定浓度范围内,随着浓度的提高,6种提取物抗氧化活性不断增强,其中,中等极性乙酸乙酯萃取物和正丁醇萃取物具有较强的清除DPPH自由基能力和还原Fe3+能力,为香樟枝功能性抗氧化剂提取物的利用提供了科学依据。The antioxidant activities of 6 different polar extracts of branches were evaluated by in vitro antioxidant methods, including DPPH free radical scavenging and reduction ability evaluation protocols. The results indicated that the antioxidant activity enhanced with the increase of concentration in a definite concentration range. Meanwhile, the medium polar ethyl acetate and n-butyl alcohol showed significant activities to scavenge DPPH free radicals and the reducing power of Fe3＋. The investigation results will provide scientific clues for developing functional antioxidants from Cinnamomum camphora branches.
