Abstract: Objective: To establish an analytical method for rapid identification of chemical compositions and quantitative determination of major compositions in Buyang Huanwu decoction (BYHWD) based on high performance liquid chromatography-quadrupole orbitrap mass spectrometry (HPLC-Q-Exactive MS) and high performance liquid chromatography-ultraviolet detection (HPLC-UV). Methods: The mass spectrometry information was collected in Full MS/dd-MS2 negative ion mode with HPLC-Q-Exactive MS system; the chemical compositions of BYHWD were subsequently annotated with Compound Discoverer 3.0 software and a self-built in-house compound library. Eight major compositions (paeoniflorin, gallic acid, hydroxysafflor yellow A, ferulic acid, calycosin-7-glucoside, ononin, calycosin, formononetin) were picked out and their contents were quantitatively determined with HPLC-UV analysis. Results: A total of 178 compounds in BYHWD were tentatively identified. The results of HPLC-UV quantitative analysis showed that 8 compositions had a good linear relationship in their respective concentration range (R2≥0.9990), the relative standard deviations (RSD) of precision and stability were all less than 15%, and the recovery rate RSD was between 1.6% and 2.4%. Conclusions: The method established in this study can realize the rapid identification and accurate quantification of the major compositions in BYHWD. Paeoniflorin, hydroxysafflor yellow A and gallic acid may be used as quality control markers.
