| 摘 要： | 采用DPPH法、ABTS法测定几种特色蔬菜的抗氧化活性，采用福林酚法测定蔬菜中总酚含量，分光光度法测定总黄酮含量并与抗氧化结果进行相关性分析。结果表明：生菜类、芳香类蔬菜具有较高抗氧化活性，IC50值为0．1—0．7mg／mL。统计学结果表明，总多酚、黄酮含量和DPPH、ABTS的IC50值有显著的负相关（P〈0．05）。

| Abstract: | DPPH and ABTS scavenging methods were used to investigate the antioxidant activity of several specific vegetables. The content of polyphenols and flavoids were determined by Folin - Ciocaileu method and UV spectrophotometry respectively. The correlation of polyphenols and flavonoids content with antioxidant capacity were analyzed. The results showed that ： lettuce and aromatic vegetables have high antioxidant activity with IC50 value at 0. 1 - 0. 7 mg/ml. There was a significant negative correlation （ p 〈 0. 05 ） between the content of total polyphenols, flavonoids and IC50 value of. DPPH, ABTS |
