Objective: To develop a HPLC method for simultaneous determination of rosmarinic acid and salviaflaside in Xiasangju Granules. Method: An Agilent Eclipse XDB-C18 column (4.6 mm×250 mm
5 μm) was applied with gradient elution using acetonitrile and 0.1% phosphoric acid as mobile phase
and the flow rate was 1.0 mL·min-1. The UV detector was set at 319 nm. Result: The linear range of rosmarinic acid was 0.036 4-0.364 μg
and the average recovery was 99.16%. The linear range of salviaflaside was 0.004 98-0.049 8 μg and the average recovery was 98.40%(n=6). Conclusion: The method is accurate and repeatable. It can be used for quality evaluation of Xiasangju Granules.
