Abstract: A optical rotation method for the quantitative determination of tobromycin sulfate injection was described. The results showed that the method was simpler, rapid, accurate and easier. The average recovery rates was 99.40%, and coefficient of variation was 0.22%, and correlation coefficients of tobromycin sulfate were 0.9999. The product was satisfied of quality control and rapid analysis by the method.
