Abstract
Dan-Huang-Qu-Yu capsule, a Chinese herbal medicine compound preparation, is widely used for chronic pelvic inflammatory disease. In this study, a rapid, selective, and sensitive microwave-assisted extraction ultra-high-performance liquid chromatography-Q Exactive quadrupole-orbitrap high-resolution mass spectrometry method was developed for analyzing its chemical compositions. A total of 85 compounds, including 22 flavonoids, 8 terpenoids, 5 quinones, 5 phthaleolactone, 23 organic acids, and 22 other compounds were identified from Dan-Huang-Qu-Yu capsule. Among them, 35 major compounds were unambiguously detected by comparing them with reference standards and selected as quality control markers, which were simultaneously determined in Dan-Huang-Qu-Yu capsule. The established method was successfully validated and applied for simultaneous determination of 35 bioactive compounds in Dan-Huang-Qu-Yu capsule from ten sample batches. The quantitative data of the analytes were analyzed by principal component analysis for quality assessment of Dan-Huang-Qu-Yu capsule. Six compounds (e.g., astragaloside IV, salvianolic acid B, ellagic acid, chlorogenic acid, N-butylidenephthalide, and luteolin) were screened out and regarded as chemical markers for quality control of Dan-Huang-Qu-Yu capsule. The established method has been proved to be a novel and useful tool for rapid research of Dan-Huang-Qu-Yu capsule. This research will provide reference for the scientific research of traditional Chinese medicines.
