ABSTRACT
A comprehensive analytical method based on UPLC-MS/MS was developed for the simultaneous determination of thirteen components including three stilbenes (stilbeneglucoside, polydatin, resveratrol), four anthraquinones (emodin, physcion, emodin-8-ß-D-glucopyranoside, aloe-emodin), five flavonoids (epicatechin, rutin, hyperoside, astragalin,quercetin) and one phenolic acid (gallic acid) in Polygoni Multifori Caulis.The separation was carried out on a Waters BEH C18 columnï¼2.1 mm×100 mm,1.7 µmï¼with gradient elution of acetonitrile-water (0.1% acetic acid) at a flow rate of 0.25 mLâ¢min⻹, and column temperature was 35 â. The target compounds were analyzed by multiple reaction monitoring (MRM) mode. TOPSIS analysis ware performed to evaluate the samples from different areas and commercial herbs according to the contents of thirteen components. The correlation coefficients of all the calibration curves were higher than 0.991 5. The average recoveries ranged from 95.24% to 102.3%, and the relative standard deviations were less than 5%. The result of TOPSIS analysis showed that the comprehensive quality of Polygoni Multifori Caulis sample from Guangzhou was better. The developed method with good repeatability and accuracy was suitable for the simultaneous determination of multiple functional substances, which provided a new basis for the comprehensive assessment and overall control of the quality of Polygoni Multifori Caulis.
