采用火焰原子吸收光谱法测定了8种川芎样品中Mg、Fe、Mn、Zn 4种常量、微量元素的含量。元素的回收率在95.8%—100.8%之间,RSD均不大于1.634%,方法稳定可靠。结果表明,川芎样品中常量、微量元素含量丰富,依次为Mg>Fe>Zn>Mn,其中Mg的含量在3500μg·g~(-1)以上。川芎药材中高含量的Mg是否与其活血行气,祛风止痛功效有关,待进一步研究。本研究可为深入了解和探讨川芎常量和微量元素及药效机理提供参考。
Flame atomic absorption spectrometry was used to determine the contents of four kinds of macadam and trace elements Mg, Fe, Mn and Zn in 8 samples of Chuanxiong. The recoveries of the elements ranged from 95.8% to 100.8% with RSD not greater than 1.634%. The method was stable and reliable. The results showed that the content of the trace elements in the samples of Chuanxiong was rich, followed by Mg> Fe> Zn> Mn, and the content of Mg was above 3500 μg · g ~ (-1). Chuanxiong medicine in the high content of Mg whether its blood circulation, Qufeng analgesic effect, to be further studied. This study can provide a reference for further understanding and discussing the contents of trace elements and pharmacodynamics of Chuanxiong.
