Abstract: Objective:To revise the quality standard of Compound Longxuejie Capsules.Methods:Chloroform in the original standard for TLC identifications was replaced by methylene chloride and HPLC was used to revise the assay method.Agilent SB-C18 column (4.6 mm ×250 mm,5μm) was adopted with acetonitrile-0.4%phosphoric acid solution (37∶63) as the mobile phase at a flow rate of 1.0 mL· min-1 , the detection wavelength was 275 nm and the column temperature was 30 ℃.Results: The revised methods were specific.The curve of loureirin A was linear in the range of 0.0208-0.5200μg and the average recovery was 100.46%;The curve of loureirin B was linear in the range of 0.0259-0.6475 μg, the average recovery was 100.95%.Conclusion: The method is simple, accurate and reproducible and can be used for the quality control of Compound Longxuejie Capsules.
