Abstract: Objective To establish a HPLC method for the determination of three phenylethanoid glycosides in Phlomis younghusbandii. Methods HPLC analysis was performed on Symmetry C18 (4.6 mm×150 mm, 5 μm) column and the mixture of methanol-water (36:64, pH=4.5, HAc) was used as the mobile phase with a flow rate of 1.0 ml/min. The column temperature was 20 ℃ and the detection wavelength was 330 nm. Results The linear ranges of acteoside,alyssonoside,isoacteoside were 20~500(r=0.999 6), 10~130(r=0.999 5), 10~130 (r=0.999 7) μg/ml, respectively. The average recoveries (n=6) of them were all between 96% and 104%, RSD<5%. Conclusions This method was special, sensitive, accurate and with good repeatability, which could be used for quality control of Phlomis younghusbandii.
