中文摘要: 研究紫色马铃薯的总多酚主要组分和快速定量检测方法,紫色马铃薯的总多酚主要包括绿原酸、花青素和咖 啡酸,其中除花青素以外的总多酚可以采用绿原酸为对照品在 325 nm 处直接测定,方法简单易行,准确度高,回收率在 97.67 %~103.15 %;并针对硒元素对紫色马铃薯酚类化合物如绿原酸、咖啡酸和花青素的代谢积累进行研究,结果表明, 硒元素显著的促进了紫色马铃薯的绿原酸、咖啡酸和花青素以及有益微量元素有机硒元、锌和铁的积累;因此富硒紫色 马铃薯是一种更好的功能食品。

Abstract:In this study, selenium enriched purple potatoes were studied. The results were: the main phenolics of purple potato tubers were chlorogenic acid, caffeic acid and anthocyanins; total phenolics could be quantified by direct spectraphotographic method at 325 nm, with chlorogenic acid as standard, recovery 97.67 %-103.15 %; trace minerals as zinc, iron and selenium and the total phenolics as chlorogenic acid, caffeic acid and antho- cyanins were significantiy increased by selenium. In conclusion, selenium enriched purple potatoes could be used as a more valuable functional food.
