摘要
对野生和栽培薇菜营养成分进行比较研究,为进一步开发利用薇菜资源提供依据。分别采用常规分析方法、电感耦合等离子体光谱分析仪(ICP)半定量分析、氨基酸自动分析仪等方法对野生薇菜和栽培薇菜的营养成分进行测定,并比较两者的差异。二者在叶绿素、总糖含量上差异极显著(P值分别为0.006和0.002),粗蛋白含量差异不显著,野生和栽培薇菜的氨基酸含量呈现不规则变化。薇菜含有多种矿质元素,包括人体必需的部分微量元素Fe、Zn、Mn、Cu,其中野生种的K和P元素的含量高于栽培种,而栽培种的S元素的含量高于野生种。
In order to exploit the resource of Osmunda japonica Thunb,the composition of nutrients in wild and cultivated Osmunda japonica Thunb were comparatively analyzed by routine analytical analysis,ICP semi-quantitative analysis and automatic amino acid analyzer.A significant difference in the contents of chlorophyll and polysaccharides between both species was observed（P =0.006 and 0.002,respectively）.The content of crude protein had a little difference between both species.In addition,the content of amino acids revealed irregular variations between both species.Moreover,a variety of mineral elements such as Fe,Zn,Mn and Cu in Osmunda japonica Thunb were detected.The contents of K and P elements in wild Osmunda japonica Thunb were higher than those in cultivated species,while the content of S was the opposite.
