A Liquid Chromatography-Tandem Mass Spectrometry Method for Simultaneous Quantitation of 10 Bioactive Components in Rhus verniciflua Extracts

초록

The purpose of this study was to develop a simultaneous method to quantify 10 bioactive compounds in Rhus verniciflua extracts using high-performance liquid chromatography-tandem mass spectrometry. The chromatographic separation was performed using a C-18 column under gradient elution with 0.1% formic acid and acetonitrile as the mobile phase solvents. The analyteswere detected in the negative-ion mode using multiple-reaction monitoring detection with an electrospray ionization interface. The calibration curves for all the analytes showed good linearity (r(2) > 0.997) over the concentration range of 1-1,000 ng/mL. The recovery valueswere within 89.53-110.14%, and the intra- and interday coefficients of variation were <4.86% for all the tested compounds. The developed method was successfully applied to a quality assessment of the R. verniciflua extract samples.
