Abstract
A HPLC method for determination of the bitter principles, bitrex, quassia and sucrose octaacetate, next to other ingredients in Specially Denatured Alcohol formulations is described. The method is based on evaporation of a sample, extraction of the residue with hexane and analysis of the extracted residue on a Cyano-type column with acetonitrile-water used as the eluent. Baseline separation of compounds and satisfactory quantitation has been achieved. Samples without pretreatment can occasionally be analysed with slight modifications of the procedure.
