OBJECTIVE To study the anti-platelet effect and influence of Radix Paeoniae Rubra and Radix Paeoniae Alba on rat's endogenous metabolites by animal experiment and UPLC-MS based metabolomic method. METHODS After administration of 80% ethanol extracts of Radix Paeoniae Rubra and Radix Paeoniae Alba for 6 d, the serum samples were analyzed by ultra-performance liquid chromatography- mass spectrometry (UPLC-MS) and partial least squares-discriminant analysis (PLS-DA) to find out the potential biomarker. RESULTS Both of the extracts of Radix Paeoniae Rubra and Radix Paeoniae Alba have good effects of inhibition on platelet coacervation, and the effect of Radix Paeoniae Alba is better than that of Radix Paeoniae Rubra. Malic acid, alpha-acetone dicarboxylic acid, leukotrieneA4 (LTA4), prostaglandinE2 (PGE2) and prostaglandin F2alpha (PGF2alpha) are proved to be significant expressed biomarkers. CONCLUSIONS Metabolomics is helpful for the further research of the mechanism of anti-platelet action of Radix Paeoniae Rubra and Radix Paeoniae Alba.
