几种特色蔬菜抗氧化作用的研究
Antioxidant Capacity of Some Specific Vegetables
【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0.1-0.7 mg/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 0.1-0.7mg/ml.There was a significant negative correlation(p<0.05) between the content of total polyphenols,flavonoids and IC50 value of.DPPH,ABTS
