摘要 采用密度泛函理论计算方法对原生橄榄油中两种酚类化合物的抗氧化性进行研究.以O—H键解离能(O—HBDE)和电离势IP作为理论参数,发现在不同的溶剂中,抗氧化剂的抗氧化性能不同.在非极性溶剂中,Hydroxytyrosol acetate的抗氧化性要好于Hydroxytyrosol,而在极性溶剂里,Hydroxytyrosol的抗氧化性要好于Hydroxytyrosol acetate. Density functional theory method is employed to calculate O-H bond dissociation enthalpies （BDE） and ionization potentials （IP）of two Phenolic components in olive oil, by which their antioxidant activities are studied. It is found that their antioxidant activities are different in the different solvents. In the non- polar solvent the order of antioxidant activity is Hydroxytyrosol acetate 〉 hydroxytyrosol, while polar solvent Hydroxytyrosol 〉 Hydroxytyrosol acetate.
