Character study of content and correlativity of elements in Radix Astragali obtained from different regions / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHOD</b>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).</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>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.</p>
