A selective and specific high-pressure liquid chromatographic (HPLC) method for the simultaneous assay of Clanfenur and its metabolites in biological fluids of interest has been developed which is suitable for routine analysis, using micro volumes (0.1 ml) of plasma samples only. After protein precipitation the extract is analysed by reversed-phase HPLC with UV detection. Excellent recovery, linearity, accuracy and precision (less than 5% for plasma) are achieved by the assay which is able to quantify Clanfenur and its metabolites in plasma at concentrations between 0.025 and 5.0 mg l-1.

UI MeSH Term Description Entries
D007202 Indicators and Reagents Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
