| 摘 要： | 目的测定甘肃产秦艽、野生黄管秦艽及栽培黄管秦艽中的铁、锰、镍、铜、锌、钙、镁、铬等8种微量元素含量。方法采用微波消解-火焰原子吸收分光光度法。结果该方法的加标回收率为88．1％～114．5％，RSD〈3．18％。秦艽中铁、锰、镍、铜、钙、镁的含量较高，而黄管秦艽中锰、锌、铬的含量较高。结论野生黄管秦艽和栽培黄管秦艽的元素含量有所差异，特别是铁的含量有较大差异，这可能与二者的生长环境有关。

| Abstract: | Objective To determine the contents of elements Fe, Mn, Ni, Cu, Zn, Ca, Mg and Cr in Gentiana macrophlla and Gentiana officinalis. Methods The contents of elements were determined by flame atomic absorption spectrometry. Results The recovery rates obtained by standard addition method were between 88.1%-114.5%, and the RSDs were lower than 3.18%. Gentiana macrophlla is rich in the trace elements such as Fe, Ni, Cu, Ca, Mg, and Gentiana officinalis is rich in the trace elements such as Mn, Zn, Cr. Conclusion There are some difference between wild and planted Gentiana officinalis in element content, that may be related to their growing environment. |
