| 中文摘要: |
| 茶多酚具有较强的抗氧化性，对多种疾病具有预防和治疗作用。为了解茶多酚与其他抗氧化剂之间的协同抗氧化作用，通过体外清除自由基和FRAP 总抗氧化能力测定，研究茶多酚与维生素C/E 复合物对各种自由基的清除率。结果表明，在茶多酚较低浓度（50、100 mg/L）时，维生素C/E 没有显著增强茶多酚清除各种自由基的能力，而在茶多酚较高浓度（200~400 mg/L）时，维生素C/E增强了茶多酚对各种自由基的清除能力。同时，维生素C/E 显著提高了高浓度茶多酚的FRAP 值，这也说明高浓度茶多酚与维生素C/E 在总抗氧化方面具有很好的协同效应。 |
| 英文摘要: |
| Tea polyphenols has strong antioxidant activity, which shows preventive and therapeutic effects on a variety of diseases. In order to understand the synergistic anti-oxidative effects between tea polyphenols and other antioxidants, we tested the antioxidant capacity of tea polyphenols and vitamin C/E by scavenging free radical and total antioxidant capacity determination. The results showed that, at the lower concentration of tea polyphenols (50 mg/L and 100 mg/L), vitamin C/E did not significantly enhance the effects of tea polyphenols on scavenging various free radical. But at the higher concentrations (200~400 mg/L), vitamin C/E enhanced the effects of tea polyphenols on scavenging various free radicals. Meanwhile, vitamin C/E also increased remarkably the FRAP value of tea polyphenols at the higher concentrations, which meand that tea polyphenols and vitamin C/E had an obvious synergistic antioxidant effect at the higher concentrations. |
