摘要(Abstract):

目的:研究中药材黄芪中元素的分布规律及其与药材产地之间的关系,从元素组学的角度为黄芪中药材建立无机元素的特征图谱提供理论支持。方法:采用ICP-MS电感耦合等离子体质谱仪,辅以原子荧光和原子吸收分析方法,对选自7个不同省份40份黄芪样本中的42种元素进行了测定和分析,应用SPSS统计分析软件分析了黄芪中元素间的相关性。结果:①不同产地黄芪中无机元素的含量呈现相似的元素谱排列,其表现为的上下起伏的波浪状分布,稀土元素含量的波浪状分布更具规律性,即原子序数为偶数的元素比相邻原子序数为奇数的元素的含量高,并随质量数的增加含量依次降低。②不同地域的黄芪中各元素的绝对含量存在较大差异。③黄芪药材中部分元素间存在相关性。结论:黄芪中元素含量呈现特征的上下起伏的波动折线元素谱。由于受土壤、气候以及自然环境的影响,各产地黄芪药材中元素的绝对含量呈现地域性差异。山西、甘肃、内蒙古几个黄芪药材道地产地以及黑龙江等地区所产黄芪药材的质量较好。
Objective: To study the characters of concentration of 42 elements in Radix Astragali and make an attempt at looking for relationship between the element concentration and regions where samplers are obtained.Method: Determining the content of elements in 40 Radix Astragali samples from 7 different provinces by ICP-MS,AFS and ASS.Analyzing the correlation of elements in Radix Astragali using statistic software(Spss).Result: Firstly,similar lines of element concentration have been acquired in our research.Secondly,it is observed that the content of elements in the samples shows regional diversity.Thirdly,there are 346 correlative element pairs in correlate analysis.And some of them indicate remarkable correlativity.Conclusion: With the aid of obtained results,it is concluded that element content in Radix Astragali display special distributing line.Remarkable correlation is presented in some element pairs.The quality of Radix Astragali gained from Neimeng,Shanxi and Gansu are better than those from other regions.
