Determination and analysis of inorganic elements in Epimedium species from different regions of Sichuan province
Objective : To establish the determination method of inorganic elements in Epimedium species, and study the distribution of inorganic elements in Epimedium species from different regions of Sichuan province. Method : K,Na , Se , Hg, As, Ca , Mg, Fe , Mn , Cu and Zn were determined by flame atomic absorption spectrometry ( FAAS ) and Mo,Pb,Cd, Cr and Co were determined by graphite furnace atomic absorption spectrometry ( GFAAS). Result:There were 16 inorganic elements in all materials. The contents of K, Na, Ca, Mg, Fe and Mn in Epimedium species were higher than that of other elements. When the FAAS was used , the recovery was 99. 0％ - 103. 9％ with RSD of 0. 56％ - 1. 8％. When the GFAAS was used, the recovery was 99. 4％ - 101. 5％ with RSD of 0. 21％ - 2. 5％.Correlation coefficient of each element was 0. 9990 - 1. 0000. Conclusion : The method is simple, rapid, accurate and applicable for the content determination of inorganic elements in Epimedium species. The results provide valuable data for quality assessment , medicinal use and the cultivation base choices of Epimedium species.
