Abstract:
OBJECTIVE: To establish a RP-HPLC method for the simultaneous determination of chloramphenical,dexamethsone sodium phosphate and deoxyepinephrine in luxindi eye drops.METHODS: The determination was performed on Kromasil C18 column and the mobile phase consisted of methanol-water(containing 0.2% triethylamine and 0.15% octane sulfonic acid sodium,pH was adjusted to 3.8 with phosphoric acid,40∶60) with flow rate at 1.0 mL?min-1.The detective wavelength was set at 230 nm;the sample size was 20 ?L and the column temperature was set at room temperature.RESULTS: The linear ranges of chlormphenical,dexamethasone sodium phosphate and deoxyepinephrine were 125～1 000(r=0.999 3),25～200(r=0.999 6) and 12.5～100(r=0.999 2) mg?L-1,respectively,with the average recoveries rate at 99.53%,100.0% and 99.24%,and RSD at 0.51%,0.90% and 0.72%,respectively.CONCLUSIONS: This method is simple,rapid and accurate,and it is applicable for the content determination of this preparation.
