OBJECTIVE:To prepare oxprozion emulsion, establish an UV spectrophotometry for the determination of oxprozion emulsion and observe the anti inflammation effect.METHOD:The oxprozion emulsion with Carbomer 940 as the excipient was determined by an UV spectrophotometry at 287±1nm. The effect was valued by inflammatory trial of mice ear. RESULTS:The average recovery was 99.59%, RSD was 1.26%. The rate of mice ear swelling was 1.92±0.5mg.CONCLUSION:The preparation of oxprozion emulsion was simple and its qua...
