Determination on Mineral Elements Content in Different Organs and Processed Products of Sichuan Aconitum carmichaeli Based on ICP-AES

[Objective] This study aimed to provide reference to further research and develop the traditional Chinese medicine Sichuan Aconitum carmichaeli.[Method] With nitric acid-high temperature ashing method,this experiment digested the mineral elements in the root,stem,leaves and its processed products such as Heishunpian,Baifupian and Huangfupian,and detected the mineral elements content in digestion solution by plasma-atomic emission spectrometry.[Result] The detection results showed that K,Fe and Zn content is relatively rich in the samples,among which,Cu content in the root is the highest,i.e.349.8 μg/g;K,Ni and Zn content in the stem is the highest,i.e.respectively 23 920.0,8.7,500.5 μg/g;Mn,Fe content in the leaves is the highest,i.e.respectively 29.7,40 375.0 μg/g;Mo,Sr content in Heishunpian is highest,i.e.1.2,1 981.0 μg/g respectively;Cr content in Huangpupian is the highest,i.e.95.5 μg/g.The standard recovery of the detection method is 92.00%-109.40% and the relative deviation is 0.29%-3.42%,which show a quite high precision and accuracy.[Conclusion] The mineral elements content in different organs and processed products of Sichuan Aconitum carmichaeli vary significantly.
