Notes:
A fluorodensitometric assay was developed for quantitative analysis of patulin in apple products. The procedure involves extraction of patulin from apple products with ethyl acetate, cleanup with silica gel column chromatography and preparative thin-layer chromatography. A fluorescent derivative, obtained by exposure of patulin on thin-layer chromatographic plates to concentrated ammonia fumes, permits convenient quantitative fluorodensitometric assay of patulin. The detection limits were 0.1 μg of pure patulin and 1.0 mg of patulin per liter of apple juice. The mean fluorodensitometric recovery of patulin from apple juice was 97.5%.
