摘要
测定了华南地区常见的38种果蔬的抗氧化活性值和总酚含量,并比较了两者的相关性。结果表明:大多数果蔬都具有一定的抗氧化活性,其中,姜、紫包菜、香蕉、草莓、乌榄的抗氧化活性较强。38种样品的水溶性总酚含量在15.37～339.48mg/100g之间。全体样品的抗氧化活性值与总酚量的相关系数r=-0.47;将样品按特征成分进行分类后,各类样品的抗氧化活性与总酚含量的相关系数分别为:花青素类r=-0.58;叶绿素类r=-0.59;胡萝卜素类r=-0.41;类黄酮类r=-0.81;其它样品r=-0.42,由此说明果蔬抗氧化活性的强弱与果蔬所含特征成分具有较大的关联性。
The antioxidant activity and water-soluble total phenols content of 38 fruits and vegetables gathered from south of china (edible portion)were assayed by using the bleaching of β-carotene-linolic acid model assy, The correlation of activity and content was compared. It was found that ginger、purple cabbage、banana、strawberry and black olive had the higher antioxidant activity. The water -soluble total phenols content of all samples ranged from 15.37 to 339.49mg/100g.The correlation between the antioxidant activity and total phenols content of all samples was r=-0.47.After classifying on the basis of the characteristic component of the samples,the correlation between the antioxidant activity and total phenols content of the anthocyanin,chlorophyll and flavonoid was r=-0.58,-0.59and -0.81respectively.So it could the inferred that there was a high correlation between the antioxidant activity and the characteristic components of the fruits and vegetables.
