Abstract: Objective To explore the effect of different durations of continuous steaming(0~48 h) with black bean decoction specified in “Chinese Pharmacopoeia” on the contents of main chemical components, and provide a reference for safe drug use of Polygoni Multiflori Radix(PM). Methods Pharmacopoeia-defined steamed samples were prepared before an analytical method of ultra-performance liquid chromatography with triple quadrupole mass spectrometry (UPLC-QQQ-MS/MS) was established for determination of 24 components in PM grown in Gaozhou, Guangdong Province. Results A UPLC-QQQ-MS/MS method was established for quantification of stilbene glycosides, anthraquinone, flavonoids and phenolic compounds in PM. With the extension of durations of steaming, the contents of the 24 components changed significantly. The contents of most of stilbene glycosides, anthraquinones and flavonoids decreased while those of phenolic components increased. Conclusion This method is simple, accurate and repeatable, which can be used for quantitative detection and analysis of the 24 chemical components in PM. There are strong correlations between the contents of the 24 components in PM and the durations of steaming in that the contents of stilbene glycosides, anthraquinones, flavonoids and phenols change regularly, which impact the side effects and tonic effects of PM.
