Objective: To study the effect of different processing methods on stilbene glycoside and anthraquinones in Polygoni Multiflori Radix (PMR) decoction

in order to provide the basis for establishing suitable processing methods for PMR decoction. Method: Different slice thicknesses

drying methods and temperatures were adopted to process PMR samples. TLC method was adopted to qualitatively analyze PMR. Stilbene glycoside and anthraquinones were determined by HPLC to define the effect of different processing methods on the quality of PMR decoction. Result: TLC showed obvious spot characteristics. Different drying temperatures and drying methods had a greater impact on the content of effective components in PMR. Samples dried in the sun had the highest content according to the comprehensive analysis. Different slice thicknesses had a certain effect on the content of effective components;6 mm slices contained more than 3 mm slices. Conclusion: Different processing methods had a greater impact on the content of effective components in PMR. In this paper

the authors provided a certain basis to improve the quality control of PMR

which is significant to ensure PMR's quality and clinical efficiency.
