Objective: To determine amygdalin content of prunus tomentosa Thunb. By HPLC. Method: Amygdalin was extracted by methanol. The seperation was performed on YWG-C 18 (10μm, 250mm×4.6mm) Column with water- methanol-ethyl nitrile as mobile phase. The flow rate was 0.6ml/min,the wavelength of UV detector was 225nm and the column temperature was 30℃. Result: The amygdalin contents of prunus tomentosa thunb.was 2.67%. Conclusion: The method was simple, accurate, rapid and with good stabilization. It was a better method for controlling the quality of prunus tomentosa thunb. [
