RESUMEN
OBJECTIVE： To conduct a comprehensive and systematic qualitative investigation on chemical components in Shengmai injection. METHODS： Gas chromatography-mass spectroscopy (GC-MS) with pre-column derivatization, rapid resolution liquid chromatography-ion trap-tandem mass spectroscopy (RRLC-IT-MSn) and ion exchange chromatography (IEC) with post-column derivatization were applied in identification of saccharides, saponins, lignins and amino acids in the sample. Furthermore, preliminary investigation on test of macromolecules was performed using size exclusion chromatography-evaporative light scattering detection (SEC-ELSD). RESULTS： Fructose, glucose, sucrose, maltose, 5-hydroxymethyl-2-furaldehyde, 19 saponins, 14 lignins and 16 amino acids were found in Shengmai injection. CONCLUSION： The proposed methods are simple and accurate. The main chemical substantial basis of Shengmai injection is clarified, laying a foundation for further assay of chemical components.
