| Abstract: | Objective:To set up a method using first order derivative spectrophotometry for the determination of nimodipine content in tablets and to eliminate interference from excipients during the assay. Method:The content of nimodipine in tablets was determinated by means of first order derivative spectrophotometry,in which the quantitative calculations were based on the peak height at 231 nm and valley height at 243 nm. Results:The correlation coefficient was 0.999 8. The average recovery was 100.75%,with a relative standard deviation of 0.70%. Conclusion:The method is simple ,rapid,accurate and reliable. |
