Hoyer GL: Pirmenol determination by high-performance liquid chromatography. J Chromatogr. 1991 Apr 19;565(1-2):497-503.
A method for the determination of pirmenol in serum is presented in this paper. The method consists of extraction of pirmenol and chlorodisopyramide (internal standard) from serum at an alkaline pH using methylene chloride. The organic extract was analysed using high-performance liquid chromatography. The mobile phase consisted of 0.01 M K2HPO4 (pH 2.4)-acetonitrile (94:6, v/v) delivered at ambient temperature and 2 ml/min through a 25 cm x 0.4 mm C18 reversed-phase column. Detection of the compounds of interest was achieved at 210 nm. The analytical method demonstrated low intra- and inter-assay variation. During the analysis of patient samples and a therapeutic drug mixture test serum, no substances that interfered with pirmenol detection were found. The method is shown to be stable, accurate, selective and sensitive enough to be utilized for the analysis of multiple samples such as may be encountered in clinical or research situations. |
