| 摘 要： | 用湿法硝化法前处理野生云南黄花稔的根、茎、叶,采用火焰原子吸收法分别对其根、茎、叶中Mg、Cu、Fe、Ni、Mn、Zn、Pb 7种微量元素进行测定。结果显示元素含量Mg>Fe>Zn>Pb>Mn>Ni>Cu;RSD在0.3%~1.6%之间。各元素在其不同用药部位的含量也不相同,Cu、Pb 2种元素的含量根>茎>叶;Ni、Fe的含量根>叶>茎;Mn、Mg、Zn 3种元素的含量叶>茎>根,说明黄花稔不同部位对各元素的富集能力不同。

| Abstract: | The Sida yunnanensis was pretreared by the methord of nitrification.Seven trace elements were determined by flame atome absorption spectrophotometer.Trace element in Sida yunnanensis are Mg>Fe>Zn>Pb>Mn>Ni>Cu.The RSD is 0.3%~1.6%.Each element in the different part of the drug content is also not the same,Cu and Pb in root>stem>leaf;Ni、Fe in root > leaf > stem;Mn、Mg、 Zn three kinds of element contents in leaf > stem > root.It showed that different parts of Sida yunnanensis have diffent ability for each element. |
