摘要

目的: 对发酵虫草菌粉中微量元素的含量进行分析评价

为制定发酵虫草菌粉中微量元素质量标准提供参考依据。方法: 采用原子吸收火焰法对发酵虫草菌粉中锌、铁、锰、铜、铅微量元素的含量进行分析。结果: 发酵虫草菌粉中微量元素的含量顺序依次为Fe>Mn>Zn>Cu>Pb。各元素方法线性关系良好

相关系数均>0.999 4;重复性试验RSD为0.54%~0.86%;回收率为96.05%~101.71%

RSD为0.32%~1.91%。结论: 该方法简单

精密度、灵敏度高

结果可靠。发酵虫草菌粉中微量元素含量均符合世界卫生组织对重金属限量的要求。

Abstract

Objective: To determine the concentration of trace elements

so as to provide information for the qualitative control of Cordyceps sinensis fermented mycelium

which is more strictly than the standard of Chinese Pharmacopoeia. Method: Flame atomic absorption technique was applied to analyze the content of zinc

iron

manganese

copper and plumbum from fermented mycelium of Cordyceps sinensis respectively. Result: The content of trace elements was listed here in order of relative quantity

Fe>Mn>Zn>Cu>Pb. All calibration curves showed good linearity (r>0.9994). The RSD of reproducibility was between 0.54% and 0.86%. The average recoveries were between 96.05%-101.71%. The RSD of recovery was between 0.32% and 1.91%. Conclusion: The method is simple with good precision and sensitivity and the result was reliable. The content of trace elements in fermented mycelium of C. sinensis is according to the requirement given by the WHO.
