    Abstract:Objective:To provide reference for rational exploiting and utilizing the plant of Radix Astragali (Huang-qi).Methods:After extracting and separating Radix Asrtagali,free amino acids in these herbs were determined by 6300 High Performance Amino Acid Analyzer were 1.734 3%,0.560 8% and 0.374 1% in proper order in Yun-nan Huang-qi, A ernestii.These trace elements was determined by atomic absorption spectrometry. Results:Contents of the free amino acids Comb.(Suo-guo Huang-qi),and A.Chrysopterus Bge.(Jin-yi Huang-qi).the content of Cu、Fe、Zn、Mg、Co、Al in different kinds of Astragalus membranaceus.Conclusion:The highest contents of free amino acids was in Yun-nan Huang-qi,the lowest was A chrysopterus Bge.There were differences among the contents of these elements in different kinds of Astragalus membranaceus. ......
