| 摘 要： | 利用空气-乙炔火焰原子吸收光谱法测定藏木香中Cu、Zn、Fe、Mn、Ca、K、Mg和Na8种微量元素的含量。该方法的回收率在96.23%—104.30%之间,相对标准偏差小于1.92%,具有较好的准确度和精密度。试验发现藏木香中微量元素含量丰富,这为藏木香的合理药用及进一步的开发利用提供了可靠依据。

| Abstract: | Eight trace elements such as Cu,Zn,Fe,Mn,Ca,K,Mg and Na in cultivated Inula racemosa Hook.f were determined by flame atomic absorption spectrometry with air-acetylene flame.The recovery was in the range of 96.23%—104.30% and the relative standard deviation was less than 1.92%.The experiment proved that there were considerable differences of the contents of the eight trace elements in cultivated Inula racemosa Hook.f.The data provides an accurate and credible evidence for reasonable medicinal use of cultivated Inula racemosa Hook.f. |
