| Abstract: | The contents of caffeine and sodium benzoate injection may be determined by P matrix method without separation of its components.BSAIC language is used for programming.The average recovery of caffeine is 100 0% and that of sodium benzoate is 99 95%.The variation coefficient of caffeine is 0 40% and that of sodium benzoate is 0 65%.On the basis of recovery rate and data observed it is concluded that this method is accurate,reliable,simple and rapid as compared with the standard pharmacopoeia regulations. |
