Abstract: OBJECTIVE To simultaneous determine the main-component dexamethasone sodium phosphate and the interfering-component ethylparaben in compound dexamethasone sodium phosphate eye drops without separation. METHODS A convolution spectrometry method has been applied. RESULTS The average recoveris and relative standard deviation were 100.8%,10%;9939%,061%,respectively. CONCLUSION This method is convenient,accuracy and suitable for routine analysis of multicomponent preparation which has interference in ultraviolet spectrum.
