Rapid Analysis of Components in Coptis chinensis Franch by Ultra-Performance Liquid Chromatography with Quadrupole Time-of-Flight Mass Spectrometry.

Coptis chinensis Franch is a traditional Chinese medical herb.In this article, ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry was used to rapidly, qualitatively, and comprehensively identify the components in Coptis chinensis Franch.Chromatographic separation was achieved on an Agilent Zorbax RRHD Eclipse Plus C18 column. The mobile phase consisted of 0.1% formic acid water (A) and 0.1% formic acid acetonitrile (B) with a gradient program. Qualitative analysis was performed on an Agilent 6540 quadrupole time-of-flight mass spectrometer, which was equipped with a Dual AJS ESI source operating in negative mode.A total of 30 alkaloid and non-alkaloid components of Coptis chinensis Franch were identified in only 14 min.This study helped to provide a basis for the quality control of Coptis chinensis Franch.Qualitative analysis method of chlorogenic alkaloids and non-alkaloids in Coptis chinensis Franch is developed by Ultra-performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) method.Established UPLC-Q-TOF-MS/MS analysis method is validated with rapidness and accuracy.The developed method was successfully applied for qualitative analysis of Coptis chinensis Franch sample collected from cultivation place in China.
