ABSTRACT: A simple and sensitive method was developed for the simultaneous determination of stilbenes, phenolic acid, flavonoids and anthraquinones in Radix polygoni multiflori by liquid chromatography tandem mass spectrometry (LC-MS/MS). The separation was completed on an Eclipse Plus C(18) (50 mm × 3.0 mm, 1.8 μm) column using 0.05% (v/v) formic acid and acetonitrile as mobile phases. The correlation coefficients of all the calibration curves were higher than 0.9990. The recoveries ranged from 95.9% to 106%. Relative standard deviations of intra and inter-day precisions were lower than 6.51%. The validated method was successfully applied to quantify stilbenes, phenolic acid, flavonoids and anthraquinones, which provided a new basis for overall assessment on quality of Radix polygoni multiflori.Journal of pharmaceutical and biomedical analysis 03/2012; 62:162-6. · 2.45 Impact Factor
