采用火焰原子吸收光谱法对藏药提宗龙胆花中Cu、Zn、Fe、Mg、Ca、K、Na 7种矿质元素进行了测定。在选定的测定条件下，提宗龙胆花中各元素间相互干扰小，对测定结果无明显影响。方法的校准曲线线性关系良好(r=0.9944—0.9999)，方法的回收率(n=6)在94.5%—107.7%之间。提宗龙胆花中K、Ca、Mg、Fe等元素含量均较高，研究结果为提宗龙胆这一传统藏药的合理开发与利用提供了可靠依据。 |

Seven metal elements,such as Cu,Zn,Fe,Ca,K,Mg and Na,in the flower of Gentiana tizuensis Franch.were determined by flame atomic absorption spectrometry(FAAS).The mutual interferences of the elements were small under the selected conditions of determination,that did not have significant effect on the results.The linear correlations of standard curves were good(r=0.9944—0.9999).The recovery of method was 94.5%—107.7%(n=6).The contents of K,Ca,Mg and Fe in the flower of Gentiana tizuensis Franch.were abundant.The results provide an credible evidence for reasonable development and utilization of traditional Tibetan medicine Gentiana tizuensis Franch.. |
