A rapid and sensitive ultrahigh‐performance liquid chromatography–tandem mass spectrometry method was developed and validated for simultaneous determination of 15 bioactive ingredients in rat plasma and tissues after oral administration of Polygonum chinense Linn extract (PCE). After addition of internal standards (ISs; rutin and danshensu), plasma and tissue samples were pre‐treated by protein precipitation with acetonitrile–ethanol. The chromatographic separation was performed on an Agilent ZORBAX RRHD Eclipse Plus C 18 column with gradient elution using a mobile phase composed of methanol and water (containing 0.2% acetic acid) at a flow rate of 0.3 mL min −1 . Mass spectrometric detection was carried out using a mass spectrometer in both positive and negative ion electrospray ionization modes by multiple reaction monitoring. The method provided excellent linearity, and the lower limit of quantification range 0.5–30 ng mL −1 for all analytes. The intra‐ and inter‐day precision were less than 9.12% and the accuracy ranged from −4.02% to 6.32%, respectively. The mean extraction recovery and matrix effect of analytes and ISs ranged from 83.65% to 109.20%. The method was successfully applied to the pharmacokinetics and tissue distribution study of 15 ingredients of PCE in rats.
