四川道地药材有川芎、黄连、川乌等数十种之多,在国内外享有盛誉。过去,对道地药材的形色气味等经验鉴别和有机成分研究较多。自80年代以来,有关中药微量元素的分析测试方兴未艾,但未见有关道地药材专题进行微量元素研究的文献报道。因此,我们对十余种川产道地药材各产地样品进行了微量元素含量测定和比较研究。 There are as many as dozens of medicinal herbs in Sichuan, such as Chuanxiong, Coptis, and Chuanwu, which are well-known both at home and abroad. In the past, there have been many empirical and organic studies on the color and odor of authentic herbs. Since the 1980s, the analysis and testing of trace elements in traditional Chinese medicine are in the ascendant, but there are no reports in the literature on trace elements in the topic of authentic medicinal materials. Therefore, we have carried out the determination and comparative study of trace element contents in samples from more than ten kinds of local origins of Sichuan medicinal herbs.
