Abstract: Objective To explore the effects of duration of steaming (0~48 h) and processing methods recorded in “Chinese Pharmacopoeia” on the contents of main chemical components of Polygoni Multiflori Radix(PM). Methods Pharmacopoeia-defined steamed samples were prepared before an ultra-high performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS) analytical method was established for determination of the 26 components in PM. Results An accurate and reliable UPLC-MS/MS method was established for the determination of anthraquinone, stilbene glycosides, flavonoids and phenolic compounds in PM. With the extension of steaming time, the contents of 26 components changed significantly. The contents of free anthraquinone components (emodin, physcion) decreased before they increased, while those of combined anthraquinone components (emodin-8-O-β-D-glucoside, Physcion- -8-O-β-D-glucoside, emodin-1-O-glucoside, emodin-6-O-glucoside), rhein, hydroxyemodin, emodin-1-methyl, cis-THSG, polydatin, epicatechin and rutin increased first and then decreased. The contents of emodin dianthrone, emodin-8-O-(6’-methylmalonyl)-glucopyranoside, physcion-8-O-(6’- methylmalonyl)-glucopyranoside, trans-THSG, resveratrol, 2,3,5,4’-tetrahydroxystilbene-2-0-(2”-O-feruloyl)-β-D-glucopyranoside, catechin and torachrysone-8-O-β-D-glucopyranoside 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 26 chemical components in PM. The contents of the 26 components in PM are closely related to the duration of steaming. Anthraquinones, stilbene glycosides, flavonoids and phenols undergo regular changes, which have an impact on the quality of PM.
