The aim of the present work was to develop a simple and rapid method of retinol acetate, tocopherol acetate and coenzyme Q 10 determination in pharmaceuticals without involving any preparation operations like separation or masking. The values of second derivative amplitude at 212 nm for tocopherol, 351 nm for retinol and 222 nm for coenzyme were used for construction of calibration graphs. Beer’s law is obeyed in the concentration range 0.5–20, 0.5–7.5 and 0.5–30 μg ml −1 for retinol acetate, tocopherol acetate and coenzyme, respectively. The elaborated procedures were successfully applied to the simultaneous determination of studied compounds in their binary synthetic mixtures and in commercial preparations with high reliability and repeatability. Spectral properties of retinol acetate allows to determine its contents in ternary mixture which includes Vitamin E and coenzyme Q 10.
