Abstract:To establish an HPLC method for determination the related substance of piracetam tablets. Method: The HPLC was carried out with C1s column, the mobile phase was a mixture of methanol and water( 10: 90), the wavelength was 210 nm and the flow rate was about 1.0 mL .min-l. Result: Piracetam and its related substances could be separated effectively by this method. Con clusion: The method is simple and reliable. It can be used to determine the related substance of piracetam tablets.
Keywords:HPLC  piracetam tablets  related substance
