江西地方品种紫山药块根功能成分

The Functional Components of Purple Yam Tubers in Jiangxi Local Varieties

从20份江西地方品种紫山药中,依据产量性状、抗病性、块根外观等筛选出较优质的地方栽培种8份,检测其块根中花青素、花色苷、总酚和锌元素含量,结果表明:花青素、花色苷、总酚含量的变异系数较大,紫山药的功能成分含量有着较大差异。应加强紫山药中功能成分的研究,为食品和加工原料时选择适宜品种提供参考。

Totally 8 local varieties were screened out from 20 Jiangxi local varieties of purple yam according to yield traits, disease re- sistance and tuber appearance, and detected anthocyanidin, anthocyanin, total phenol and Zinc in their tubers. The results showed that the variation coefficient of antbocyanidin, anthocyanin and total phenol was larger, there was great differences in the functional components of purple yarn. To strengthen the research on function and nutritional components in purple yam as the raw material of food and food processing can provide reference for selecting suitable varieties to lay foundation for the better characteristics of vegetables to the market.
