Abstract:Objective To establish a HPLC method for the determination of daphnetin, 7-OH coumarin and syringing in Zushima. Methods The separation was performed on YMC-Pack ODS (4.6 mm× 250 mm, 5 μm) column with a mobile phase consisting of methanol-0.5% acetic acid-water (19 : 8 : 1) as gradient elution at the flow rate of 1.0 mL/min. The dual detective wavelength was set at 327 nm and 266 nm. The column temperature was 30 ℃. Results Baseline separation was achieved for the analysis of the three index components. The average recoveries were 98.4%-100.2%. Conclusion This method is convenient, rapid and accurate. It can be used for quality control in production of Zushima.
Keywords:Zushima  HPLC  daphnetin  7-OH coumarin  syringin  content determination
