ABSTRACT
An accurate, simple, reproducible and sensitive method for the determination of atropine sulfate and scopolamine hydrobromide has been developed and validated. Atropine sulfate and scopolamine hydrobromide were separated using a microBondapack C(18) column by isocratic elution with flow rate 1.0 ml/min. The mobile phase composition was methanol, water, formic acid (165:35:1; v/v/v) and pH adjusted 8.3 with triethylamine. The samples were detected at 230 nm using photo-diode array detector. The linear range of detection for atropine sulfate (I) and scopolamine hydrobromide (II) were between 10.38 and 1038 microg/ml with a limit of quantification (LOQ) of 10.38, 10.00 and 1034 microg/ml with an LOQ of 10.00 microg/ml respectively. The linearity, range, peak purity, selectivity, system performance parameters, precision, accuracy, robustness and ruggedness for (I) and (II) were also shown acceptable values.
