用ICP-AES测定了秦巴山区独有的中草药钮子七中的2种常量营养性元素(钙、镁)和5种微量元素(铜、铬、铁、锌、锰)含量。钙4790.66μg.g-1、镁55.32μg.g-1、铜18.44μg.g-1、铬2.1μg.g-1、铁264.50μg.g-1、锌56.71μg.g-1、锰17.83μg.g-1,回收率均在96.2%—100.5%之间,结果表明,此方法简便、可靠,具有良好的精确度和准确性。并初步讨论了中草药钮子七中有益元素与治疗疾病的关系,并与中药材汉三七中微量元素含量相比较,二者微量元素含量略有差异。
The contents of two kinds of macronutrients (calcium and magnesium) and five kinds of trace elements (copper, chromium, iron, zinc and manganese) in the traditional Chinese medicine Tageta spp. Were determined by ICP-AES. Calcium 4790.66 μg.g -1, Magnesium 55.32 μg.g -1, Copper 18.44 μg.g -1, Chromium 2.1 μg.g -1, Iron 264.50 μg.g -1, Zinc 56.71 μg.g -1, Manganese 17.83 μg.g-1, recoveries were between 96.2% -100.5%, the results show that this method is simple and reliable, with good accuracy and accuracy. The relationship between the beneficial elements in Chinese herbal medicine and the treatment of diseases was also discussed. Compared with the content of trace elements in Chinese medicinal materials, the contents of trace elements in the two Chinese herbs were slightly different.
