Objective: To study a new quality standard of Xielong liquor. Method: Radix paeoniae alba
flos carthami and radix angelicae sinensis in the the formula were identified qualititively by TLC.The content of paeoniflorin
hydroxysafflor yellow A and ferulic acid was determined by HPLC with a Inertsil C8-3 column. The mobile phase was acetonitrile-0.1% phosphoric acid-tetrahydrofuran(18∶80∶2) with a flow rate at 1.0 mL·min-1.Detection wavelength was at 340 nm. Result: The TLC spots were clear and specific. The linear ranges for paeoniflorin
hydroxysafflor yellow A and ferulic acid were 23.35-373.56
5.57-89.08
2.42-38.72 mg·L-1 respectively. The average recoveries were 101.08%
99.85%
100.34%(n=6). Conclusion: The new established standard can be used for the quality control of Xielong liquor.
