title: [Gas liquid chromatographic analysis for quantitative determination of mefruside and oxomefruside in blood plasma (author's transl)].
abstract: A specific and sensitive GLC-analytical method was developed for the determination of mefruside, its lactone and hydroxy acid metabolites in blood plasma. It requires the derivatization of the isolated compounds with dimethyl-formamide dimethylacetal and the quantization of the derivatives using a phosphorus nitrogen detector. The method has a sensitivity limit of 2 ng mefruside/ml, 10 ng lactone/ml and 10 ng hydroxy acid/ml, respectively, using 1 ml of blood plasma per assay. It was applied to the determination of plasma levels in a dog following a single oral dose of 10 mg mefruside/kg.
