摘要: 以红菜薹21个品种(系)及7种十字花科主要蔬菜为材料,采用电感耦合等离子体发射光谱仪测定不同品种红菜薹及其不同食用部位的Ca、Mg、Fe、Zn含量,并与其他十字花科蔬菜的矿物质元素营养价值进行比较。结果表明:不同红菜薹品种(系)的矿物质元素含量差异很大,Ca、Mg、Fe、Zn元素均存在显著差异;各矿物质元素在红菜薹薹叶和花蕾中的含量均高于薹中的含量,具有较高的营养价值;与其他十字花科蔬菜相比,红菜薹矿物质元素含量综合表现位于前列,证明红菜薹具有重要营养价值。

Abstract: The contents of Ca, Mg, Fe and Zn in different parts of 21 species of purple flowering stalks were determined by inductive coupled plasma emission spectrometer (ICP), and compared with seven cruciferous vegetables. The results showed that there were significant differences on Ca, Mg, Fe and Zn in different varieties of purple flowering stalks; their concentrations were also higher in leaf and bud than that in stem, which shows that the leaf and bud are of high nutritional values. Comparing with other cruciferous vegetables, purple flowering stalks had higher concentrations on Ca, Mg, Fe and Zn, which shows that purple flowering stalks are of high edible value.

Key words: purple flowering stalks, mineral elements, different parts, nutritional assessment
