【Abstract】 Objective: To determine phellodendrine in Cortex Phellodendri by HPLC. Methods : HPLC condition consists of C 18 column (Phenomenex, 150mm, 5μ), actonitrile:250mL of 0.05mol·L -1 phosphoric acid +0.4mL of diethylamine (9∶91, v/v) as mobile phase, detection wavelength at 284nm. Results : The averagy recovery of phellofendrine was 101.43% ( RSD =1.56%, n =5) and the linear range of phellodrine was 0.4368～2.1840μg·μL -1 , r =0.9998. Conclusion : The method is simple, accurate and reproducible, and can be used for the determination of phellodendrine in Cordex Phellodendri.更多还原
