- Abstract
Huangqin Qinfei Decoction (HQD) is a traditional Chinese medicine that is administered for acute pneumonia, bronchial inflammation, acute bronchitis and acute lung infection. In this study, we used liquid chromatography linked with tandem mass spectrometry (LC-MS/MS) for the concurrent identification of 11 bioactive compounds; namely, baicalin, baicalein, wogonoside, scutellarin, wogonin, oroxylin A, geniposide, genipin, geniposidic acid, chlorogenic acid, and crocin-I, for the quality control of HQD. The evaluation was conducted on an Agilent Poroshell 120 EC-C18 (2.1mmx100mm, 2.7µm) with gradient elution in the mobile phase with 0.1% formic acid and 1mM/L ammonium acetate in water as solvent A and methanol as solvent B at a flow rate of 0.3mL/min in under 12 min. Mass spectrometric detection was conducted in the selected reaction monitoring mode utilizing electro spray ionization in the positive and negative modes. Every one of the calibration curves had good linearity with R² >0.9992. Intra-day and inter-day accuracies for every one of the evaluated components were expressed as the relative standard deviation (RSD) from 1.72%-5.02% and 0.63%-5.99%, respectively. The recuperation of the 11 compounds that were measured at the three concentrations was within 94.05%-105.18%, with the RSD ≤ 6.26%. The use of this method was determined through the effective evaluation of 11 compounds in 5 batches of HQD. The confirmed method is precise, sensitive, and effective for identifying the contents of the chosen compounds in HQD for quality control.
