| Abstract:The determinatian of two components in compound norfoxacin ointment was established Acording to different solvent selectivity of norfoxacin and clotrimazole, two components were extraected respectively with different solvents from one sample. They were determined by UV and double phase solution negative ion surfactants titration method. The average recoveries of norfoxacin and clotrimazole were 99.18%(n=4.RSD 0.83% ) and 98.95% (n=4.RSD l.02%) respectively. IN this method, equipments were simple and easy. Reagents were obtained easily. It is simple and rapid and suitable to analyse preparation(s) in the hospital. |
