Quantitative Analysis of the Twenty Marker Components in Gwakhyangjeonggi-san using Ultra-Performance Liquid Chromatography with Mass Spectrometer

Abstract

Generally, Gwakhyangjeonggi-san has been used for treatment of diarrhea-predominant irritable bowel syndrome. In this study, an ultra-performance liquid chromatography-electrospray ionization-mass spectrometer method was established for the simultaneous quantification of marker compounds 1-20 in Gwakhyangjeonggi-san water extract. All analytes were separated by gradient elution using two mobile phases on a UPLC BEH C 18 (100×2.1 mm, 1.7 μm) column and maintained at 45℃. The injection volume was 2.0 μL and the flow rate was 0.3 mL/min with detection at mass spectrometer. Regression equations of the compounds 1-20 were acquired with r 2 values ≥ 0.9950. The values of limit of detection and quantification of all analytes were 0.01-2.79 ng/mL and 0.03-8.37 ng/mL, respectively. The amounts of the compounds
