摘　　要：通过DPPH自由基和ABTS+自由基清除率以及油脂过氧化值的测定,对可可脂体外抗氧化能力进行评价,并将可可脂应用于护肤霜中,对其功效进行评价。结果表明:可可脂多酚具有很好的抗氧化活性,其清除DPPH自由基和ABTS+自由基的半数效应浓度(EC50)分别为11.61和10.59 mg/L,优于维生素C和维生素E;天然可可脂能有效抑制油脂的氧化,效果与用量呈正相关;添加可可脂能有效提高护肤霜的保湿性,增强美白效果,改善皮肤弹性,对皮肤安全、无刺激性。The vitro antioxidation activity of cocoa butter was evaluated by the determination of scavenging ratio of DPPH free radicals and ABTS ＋ free radicals, as well as oil peroxide value （POV）. Results showed that the cocoa butter polyphenols display good antioxidation activity, the half maximal effective concentration （ ECs0 ） value of DPPH free radicals and ABTS ＋ free radicals is 11.61 and 10. 59 mg/L respectively,which are better than that of vitamin C and vitamin E. Natural cocoa butter can effectively restrain the oxidation of oils and fats, and the effect is directly correlated with the dosage. Adding natural cocoa butter into cosmetic creams can effectively raise the moisturizing performance, upgrade the whitening effect and improve the skin elasticity. Meanwhile, it is safe for human skin and no skin irritation displays.
