Objective To establish the HPLC fingerprint of Rebitong Mixture and to simultaneously determine the contents of paeoniflorin, naringin, baicalin, and asperosaponin Ⅵ in Rebitong Mixture by HPLC method.Methods The fingerprint analysis was adopted on Agilent 1260 C18 (250 mm×4.6mm, 5 μm) with the mobile phase consisted of acetonitrile - 0.2% phosphoric acid flowing at 1.0 mL/min in gradient elution manner, and the detection wavelength was set at 212 nm with column temperature 30 ℃. Similarity of fingerprints was evaluated, and cluster analysis (CA), principal component analysis (PCA) and orthogonal partial least squaresdiscriminant analysis (OPLS-DA) were used to analyze the sample patterns. The contents of paeoniflorin, naringin, baicalin, and asperosaponin Ⅵin Rebitong Mixture were determined by HPLC method on Agilent 1260 C18 column (250 mm×4.6 mm, 5 μm). Acetonitrile - 0.2% phosphoric acid was used as the mobile phase by gradient elution. The detection wavelength were 230 nm for paeoniflorin, 280 nm for naringin and baicalin, and 260 nm for asperosaponin Ⅵ. The flow rate was 1 mL/min, the column temperature was 30 ℃, and the injection volume was 10 μL.Results There were 26 common peaks in the fingerprints of 10 batches of Rebitong Mixture samples, and the similarity was all above 0.99. The 10 batches of samples were divided into 2 categories with chemical pattern recognition, and four peaks that had a greater impact on the quality of preparations were selected by OPLS-DA analysis. The linearity of paeoniflorin, naringin, baicalin, and asperosaponin Ⅵ was 27.238 — 272.384, 38.207 — 382.066, 77.864 — 778.642, 51.015 — 510.015 μg/mL, and the average recoveries were 95.34%, 103.51%, 103.51%, and 102.68% with RSD values of 0.65%, 1.12%, 0.86%,and 2.41%, respectively.Conclusion The method is accurate, reasonable, and reproducible, and can be used for the quality control and evaluation of Rebitong Mixture.
