Polygonum capitatum, a traditional Miao medicinal plant, has significant effects on the treatment of urinary system infections and pyelonephritis. However, no study about the comprehensive quality evaluation of P. capitatum has been reported. In this contribution, a rapid and validated method based on HPLC coupled with triple quadrupole MS was established for the simultaneous determination of six active flavonoids, six phenolic acids, and a lignan in extracts of P. capitatum. (18) analytical column with gradient elution. All analyses were performed on an Agilent XDB C-18 column (2.1 x 100 mm, 3.5 m) with a linear gradient elution of acetonitrile/water. r(2), 0.9923-0.9992), precisions (RSD, 1.0-3.0%), repeatability (RSD, 2.0-3.2%), stability (RSD, 2.2-3.2%), and recovery (RSD, 2.1-3.6%) of the 13 compounds. P. capitatum. Moreover, our study can provide chemical evidence to reveal the material basis of its therapeutic effects.
