title: Fluorometric and GLC analyses of aristolochic acid.
abstract: Aristolochic acid is a natural product with possible implication in Balkan endemic nephropathy. A convenient fluorometric assay for the compound is described based on reduction to the lactam and measurement of the intensity of fluorescence. The limit of sensitivity was 0.05 mug/ml. A GLC assay is also described, based on flash methylation of aristolochic acid and its lactam using trimethylanilinium hydroxide. Conditions for optimum performance with a sensitivity limit of 1-5 mug/ml are described.
