| Abstract: | OBJECTIVE To establish a measure to determine the content of piracetam in compound piracetam and nimodipine capasules by HPLC.METHODS Using US Agilent High Performance Liquid Chromatograph Instrument,the mobile phase was methanol-water(10∶90),the flow rate was 1.0mL·min-1,the UV detection wavelength was 210 nm,the column temperature was 35℃.RESULTS The content of piracetam within the range of 20.31～203.1μg·mL-1 shows a good linearity(r=0.9999) and its recovery is 99.2%.CONCLUSION This method can be used as a measure to determine the exact content of piracetam in compound piracetam and nimodipine capasules and as a control over product quality as well. |
