Investigation of Chemical Constituents and Sources of Zhishi Xiebai Guizhi Decoction by LC-MS/MS / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents of Zhishi Xiebai Guizhi decoction and its single agent by high performance liquid chromatography-mass spectrometry to provide a scientific basis for the quality evaluation and control. METHODS: Agilent XDB-C18(4.6 mm×250 mm, 5 μm) column was used for HPLC analysis with acetonitrile-water as mobile phase by gradient elution. Using liquid chromatography-mass spectrometry technology to collect data in positive and negative ion mode, combined with literature reports, the main chemical components of Zhishi Xiebai Guizhi decoction were analyzed and identified. RESULTS: A total of 19 compounds were identified from Zhishi Xiebai Guizhi decoction. The main components are naringin, neohesperidin, etc. The main component types include alkaloids, steroidal saponins, glycosides, flavonoids, etc. CONCLUSION: This study comprehensively clarified the chemical composition of Zhishi Xiebai Guizhi decoction, and it has important reference value for the identification and quality evaluation of Zhishi Xiebai Guizhi decoction.
