Objective To establish the method for determination of acteoside in Lamiophlomis rotata (Benth.) Kudo. Methods Acteoside was determined by the HPLC with Diamonsil C18 column, the mobile phase consiste of acetonitrilemethanol1% acetic acid(10∶15∶75), flow rate of 1.0 mL/min, UV detection wavelength of 334 nm, and column temperature of 35 ℃. Results This method was linear over ranges of 0.227 2~1.363 2 μg (r=0.999 2) for acteoside. The results of tests for the average recovery, precision, stability, and repeatability accord with the requirements. Conclusion This method is special,ensitive, accurate, and having good repeatability, and can be used for the quality analysis of phenylethanoid glycosides in L. rotata.
