The purpose of this article is how to use HPLC technique for quantitive analysis of cholesterol in some foods. The best conditions are studied for this analysis including composition of mobile phase, temperature, flow rate, the wavelength of detector UV-VIS, and acidity of mobile phase. The column used for cholesterol determination by this method was: C18(5μm,250x4.6mm) with injection volume of 20μL. Methanol 100% was used as mobile phase.
