| Abstract: |
| UV and zero-crossing derivative spectrophotometry has been used to determinemixtures of theopbylline and cimetidino. The samples were determined by UV at 271 1 um fortheophylline and by zero-crossing derivative spectrophotometry fer cimetidine without any |
| Key words: theophylline cimetidine determinatlon zero-crossingderivative spectropbotometry |
