Identification of Chemical and Metalobic Components of Fufang Suan-Zao-Ren-Tang Decoction by High Performance Liquid Chromatography-Electro Spray Ion Trap Mass Spectrometry
Chemical components of Fufang Suan-Zao-Ren-Tang decoction and their metabolites in rats were identified by HPLC-ESI-MS.Samples were separated by a Zorbax C18 column using a binary gradient elution,and analyzed by HPLC-ESI-MS.The ions of compounds in negative modes were observed for molecule mass information,and the potential structures were identified by attentive studying on the mass spectra of compounds and comparing with reference data and some of standards.It is the first time to establish an analysis method using HPLC-MC to identify the chemical and metalobic components of Fufang Suan-Zao-Ren-Tang decoction.Further research about Suan-Zao-Ren-Tang decoction can base on this analysis method.
The present invention provides a process for the preparation of an enriched carboxylic acid compositions produced by the method of composition of the carboxylic acid is included in contact with the enrichment feed in the enrichment zone. The present invention is then to remove the catalyst from the carboxylic acid composition to a method and that the resulting composition for the preparation of a catalyst removal composition.
