Determination of Aripiprazole in Human Plasma by HPLC / 中国药房

ABSTRACT

OBJECTIVE: To establish a HPLC method for the determination of aripiprazole in human plasma by HPLC. METHODS: The plasma sample was determined by HPLC after subjected to liquid- liquid extraction .The separation was carried out on C18 column with clolumn temperature at 40℃. The mobile phase consisted of 0.03mol?L-1 ammonium acetate-acetonitrile(3466) with a flow rate of 0.8mL?min-1 and detective wavelength of 257nm.The sensitivity was 0.01 AUFS. RESULTS:The linear range of aripiprazole was 5.0～600.0ng?mL-1(r=0.999 5) .The recovery rate was above 90% .CONCLUSION:The method is sensitive,accurate and rapid,and suitable for the determination of aripiprazole in human plasma.
