Serum pharmacochemistry of honey-fried Stemona tuberosa Lour. by UHPLC-QTOF/MS and MetaboLynx analysis / 药学学报

ABSTRACT

A high throughput UHPLC-QTOF/MS method was established to analyze and identify the constituents in rat plasma after oral administration of honey-fried Stemona tuberosa Lour. extract. Automated data analysis software MetaboLynx was developed in analysis and identification of the bioactive components and their metabolites in rat plasma following oral administration of honey-fried S. tuberosa Lour. extract. As a result, 40 compounds including 12 prototype components and 28 metabolites were characterized. The constituents absorbed into blood and the possible metabolites which were demonstrated to originate from the active fraction of honey-fried S. tuberosa Lour. were responsible for the observed efficacy. Its serum pharma­cochemistry should be subjected to complete investigation to illuminate the pharmacology and active mechanism of honey-fried S. tuberosa Lour.
