用半经验量子化学方法ＡＭ１计算了茶多酚四种成分ＥＧＣＧ、ＥＧＣ、ＥＣＧ和ＥＣ的△ＨＯＦ值、ＨＯＭＯ能级，以此为理论指标从不同机制比较了它们的抗氧化活性，解释了实验所得的结论，并进一步探讨了ＥＧＣＧ与其他黄酮抗氧化剂活性差异的原因。
The △ HOF values and HOMO energy levels of four components of tea polyphenols EGCG, EGC, ECG and EC were calculated by semi-empirical quantum chemical method AM1, and their antioxidant activities were compared from different mechanisms. The results of experiments The conclusion was reached and the reasons for the difference in antioxidative activity between EGCG and other flavonoids were further explored.
