Abstract: Objective :To establish a method for the determination of the content of procaine hydrochloride in cradiac standstill solution. Method:Ultraviolet spectrophotometric method was used to directly determine the content of procaine hydrochloride.The wavelength of detection was 290nm. Results :The liner range was 0.5～8μg/mL(r=0.999 9).The relative recovery of the method was 98.59% with RSD of 0.033%. Conclusions : This method is simple,rapid,accurate and can be used to determine the content of procaine hydrochloride in the preparation.
