| Abstract: | A UV spectrophotometry has been developed forthe simultaneous quantitation of minoxidil and tretinoin in compound minoxidilliniment.The method is based on measuring the first derivative signals(D)of minoxidil at278.5 nm and the zero derivative signals(A) of tretinoin at 337 nm respectively.Withoutany interference from each other,or any other coexisting materials.The average recoveriesof minoxidil and tretinoin were 101.2% and 98.4%.RSD was 0.78% and 0.82%.The resultsillustrate that the method is simple,rapid,accurate and sensitive. |
