Abstract:Objective : To establish HPLC method for determine of Piperine in Fructus piperis longi. Methods : Using ODS column, Methanol -Water (77: 23)as the mobile phase at flow rate of 1. OmL ·min^-1, wavelength of the detection was 343 nm. Results : Liner range of Piperine was 0.04116 μg -0. 4116 μg ( r = 1. 0000) ; the recovery was 103.2% ( RSD = 1.3% ). Conclusion : This method is simple, rapid, accurate, highly sensitive and well reproducible.
