目的：研究甘草、诃子提取物复合抗氧化剂对葵花籽油抗氧化作用的影响。方法采用Schaal烘箱法和ABTS法,评价复合抗氧化剂对葵花籽油的抗氧化作用。结果 Schaal烘箱加速氧化实验中,甘草提取物比诃子提取物对葵花籽油的抗氧化作用更强,复合抗氧化剂均表现出协同抗氧化作用,其中,0.007%甘草提取物+0.013%α-生育酚、0.015%甘草提取物+0.005%抗坏血酸、0.007%诃子提取物+0.013%α-生育酚和0.003%诃子提取物+0.017%抗坏血酸对葵花籽油的抗氧化作用较强,均优于其单一抗氧化剂和人工合成抗氧化剂丁基羟基茴香醚(BHA)、2,6-二叔丁基-4-甲基苯酚(BHT),弱于2-叔丁基对苯二酚(TBHQ)。ABTS 法中,多数复合抗氧化剂间表现出协同作用,其中,诃子提取物与抗坏血酸复配比例为5：1和3：1时清除ABTS自由基能力最强。结论复合抗氧化剂对葵花籽油具有协同抗氧化作用。

Objective Effects of antioxidants on the compound antioxidants of Glycyrrhiza uralensis Fisch. Extract(GUE) and Terminalia chebula Retz. Extract(TCE) on sunflower oil. Methods Due to Schaal experiment and ABTS+radical scavenging array for evaluating antioxidant capacity of compound antioxidants. Results The antioxidant activity of GUE stronger than TCE of sunflower oil and synergistic effects were observed for all antioxidant combinations by Schaal oven method, and especially for combinations of 0.007%GUE and 0.013%α-tocopherol, 0.015%GUE and 0.005%L-ascorbic acid, 0.007%TCE and 0.013%α-tocopherol, 0.003%TCE and 0.017%L-ascorbic acid, which showed a greater synergistic effect than that of the each individual antioxidant and synthetic antioxidants, such as butyl hydroxyl anisole(BHA), 2,6-di-tert-butyl-p-cresol (BHT), tert-butyl hydroquinone(TBHQ). Synergistic effects were observed for most of antioxidant combinations by ABTS+radical scavenging array, the combination of 0.017%TCE and 0.003%L-ascorbic acid, 0.015%TCE and 0.005%L-ascorbic acid showed a greatest synergistic effect than that of the others. Conclusion Synergistic effects were observed for all antioxidant combinations of sunflower oil.
