Objective:To determine the contents of 18 inorganic elements in Semen Lablab Album by inductively coupled plasma tan-dem mass spectrometry(ICP-MS/MS),and to analyze the quality of Semen Lablab Album with different origin and character difference by stoichiometry.Methods:After ultra microwave digestion,the samples were determined by quadrupole inductively coupled plasma mass spectrometry.The results were analyzed by principal component analysis and cluster analysis.Results:The linear relationship of each inorganic element was good.Six principal components were obtained by principal component analysis,and the cumulative variance contribution rate was 83.959%.The results showed that Mn、Ni、Cu、Sr、Co、Se、Rb、Ba、Cr、Cd、Ag、Li、Be、V、Pb are the main characteris-tic elements of Semen Lablab Album.Conclusion:The method is simple,accurate and sensitive.It can be used for the determination of inorganic elements in Semen Lablab Album,and provides a reference for further study of Semen Lablab Album.
