Content Determination of Aniracetam in Aniracetam Inclusion Complex by HPLC.

We established a HPLC method for content determination of aniracetam in aniracetam inclusion complex. The chromato column was Agilent ODS (4.6mm×150mm,5µm), the mobile phase was methanol-0.01 mol/L Potassium dihydrogen phosphate buffer solution (25:75, pH 3.0), with the flow rate of 1.0 ml/min, column temperature of 30° and the detection wave at 280 nm, the sample size was 20µL. A good linear relationship was obtained between the peak areas and the concentrations of aniracetam in the range from 5~80µg/ml (r=0.9998), the mean recovery was 100.1% (n=15), RSD=0.19%. This method is convenient, rapid, accurate, and brings about good recovery; it can be used for content determination of aniracetam in aniracetam inclusion complex. [ABSTRACT FROM AUTHOR]
