title: Ultra-performance liquid chromatography-tandem mass spectrometry analysis of the bioactive components and their metabolites of Shaofu Zhuyu decoction active extract in rat plasma.
abstract: A rapid, sensitive and selective ultra-performance liquid chromatography-electrospray ionization tandem mass spectrometric (UPLC-ESI-MS/MS) method was developed for analysis and identification of the bioactive components and their metabolites in rat plasma following oral administration Shaofu Zhuyu decoction active extract. The analysis was carried out on an AcQuity UPLC chromatographic instrument and a QTOF mass spectrometer using positive and negative electrospray ionization (ESI), respectively. The results showed that sixteen peaks were detected and twelve peaks, including flavones, organic acids and terpene glycosides, were identified by comparing with reference compounds. Furthermore, nine metabolites, including quercetin glucuronide sulfates, quercetin diglucuronides, isorhamnetin sulfates, isorhamnetin glucosides, and isorhamnetin glucuronides were detected and identified in rat plasma based on the mass fragmentation behaviors and literature reports. These results provided a meaningful basis for evaluating the bioactive components and their action mechanisms of complex traditional Chinese medicines (TCMs).
