Abstract
A rapid and simple high-performance liquid chromatographic (HPLC) meth od was developed for the simultaneous determination of hexadecoic and octadecanoic acids in stearin. The samples are dissolved in ethanol wi thout any additional pretreatment. HPLC was carried out on a MicroPak MCH-5 column (15cm X 4mm I.D.) using water (pH 2.5 with perchloric aci d) - acetonitrile (10/90 V/V) as the mobile phase with UV detection at 210nm.
