HE Cui-wei. Determination of Zhenggushui by GC-MS[J]. Chinese journal of experimental traditional medical formulae, 2010, 16(6): 93-96. DOI: 10.13422/j.cnki.syfjx.2010.06.062.
Objective:To analyze the chemical composition and their relative contents of Zhenggushui.Method:Acapillary column HP-5MS was used.The column temperature was controlled by a program and the MS analysis was performed with EI and quadrupolemass analyzer.The chemical composition was identified by NIST2002 searching and mass spectra comparing and their relative contents were determined by using normalization method of chromatographic peak areas.Result:There were 30components were found and 29 of them(more than 97%) were identified.Conclusion:The GC-MS is a simple
rapid and sensitive method for the chemical composition analysis of Zhenggushui.
