Abstract:
Objective To study the distribution and correlation of 20 kinds of inorganic elements (Na,Mg,A1,V,Cr,Co,Fe,Ni,Cu,Zn,Mn,As,Se,Cd,Cs,Sr,Ag,Hg,Pb,and U) in Jiawei Xiaoyao Formula (JXF).Methods The levels of 20 inorganic elements in 10 kinds of herbal substances were determined by ICP-MS with microwave digestion for sample preparation,and the results were analyzed with SPSS22.0.Results There were some correlations among the inorganic elements in JXF;Four main factors were selected by principal component analysis (PCA).The PCA results showed that Na,Mg,A1,V,Ni,Cu,Se,Sr,Cs,Mn,Hg,and Fe might be the characteristic elements in JXF;There were Mg,A1,Mn,and Fe elements in 10 herbal drugs,the contents of inorganic elements in herbal drug were different because the medicinal parts were different,and the decreasing order was roots and rhizomes,skin type,all grass,fruit seeds,and fungi.Conclusion Contents of inorganic elements can not only characterize the stability of extraction process,and can provide experimental evidence for the study of traditional Chinese medicine compound compatibility law.
