| 摘 要： | [目的]研究紫背菜（Gynura bicolor DC.）中元素分布及其与土壤的相关性,为紫背菜的种植开发及药用研究提供基础信息。[方法]采用梅花形布点法采样,以原子吸收光谱法测定了紫背菜叶、茎、根以及其生长的土壤中的Ca、Mg、Cu、Zn、Mn、Fe、Pb、Cd元素含量。[结果]8种金属元素的线性回归方程和相关系数分别为：Ca,A=0.04916C＋0.04244（r=0.9989）;Mg,A=1.163C＋0.1790（r=0.9990）;Cu,A=0.2426C＋0.000485（r=1.0000）;Mn,A=0.3151C＋0.0004726（r=0.9999）;Zn,A=0.2512C＋0.02394（r=0.9994）;Fe,A=0.09529C＋0.001277（r=0.9985）;Pb,A=0.009095C＋0.2570（r=0.9994）;Cd,A=0.09908C＋0.01033（r=0.9993）。紫背菜矿质元素含量丰富,Fe、Mg、Ca含量高,有害元素Pb、Cd含量低;各元素在组织中具有一定分布特征,并与土壤元素含量存在一定相关性,叶片对所测元素富集系数最大。测定结果相对偏差紫背菜〈5.3%,土壤〈6.1%,加标回收率为91.2%～106.6%。[结论]紫背菜具有良好的种植、食用与药用开发价值。

| Abstract: | [Objective]The aim was to study distribution of elements in Gynura bicolor DC. and its correlation with soil,which will provide basic information for planting,development and pharmaceutical study of G. bicolor DC. [Method]Using quincunx method to sample,the contents of Ca,Mg,Cu,Zn,Mn,Fe,Pb and Cd in leaf,stem,root and soil for its growth were determined by atomic absorption spectrometry.[Result] The linear regression equation and correlation coefficient of eight metal elements were:Ca,A=0.049 16C+0.042 44(r... |
