摘　　要：[目的]研究栽培型和野生型马齿苋茎叶功能成分及抗氧化作用。[方法]以栽培型马齿苋和野生型马齿苋为材料,分别对2种类型马齿苋茎和叶的主要功能成分进行分析。采用DPPH·清除试验、黄嘌呤氧化酶抗氧化和二酪氨酸/酪氨酸3种抗氧化方法对其抗氧化作用进行试验。[结果]2种马齿苋多表现为叶中功能成分高于茎。野生型马齿苋多酚、总黄酮和β-胡萝卜素茎叶总含量高于栽培型,而有机酸和多糖以栽培型马齿苋中总含量高于野生型。栽培型马齿苋抗氧化作用好于野生型马齿苋。[结论]栽培型马齿苋可以作为潜在的抗氧化资源加以利用。[Objective] To study the functional components and antioxidant effects of cultivated and wild-type purslane stems and leaves. [Method]Using cultivated purslane and wild-type purslane as materials, the main functional components of the stems and leaves of the two types of purslane were analyzed.The antioxidant activities were evaluated using 2,2-diphenyl-1-picrylhydrazyl(DPPH) assay, Xan-XOD assay and dityrosin/tyrosin assay. [Result]The two kinds of purslane mostly showed that the functional components in the leaves were higher than the stems.The total content of polyphenols, total flavonoids and β-carotene in the stems and leaves of wild-type purslane was higher than that of cultivated ones, while the total content of organic acids and polysaccharides in cultivated-type purslane was higher than that of wild-type purslane.The antioxidant effect of cultivated type purslane was better than that of wild type purslane.[Conclusion]Cultivated purslane can be used as a potential antioxidant resource.
