Improvements in the quantitation of patulin in apple juice by high-performance liquid chromatography

摘要: A method is described for Sep-Pak silica cartridge purification of patulin from apple juice followed by reversed-phase high-performance liquid chromatographic (HPLC) determination. The has a rapid sample preparation and offerts good separation other constituents. 80-87% recovery at 3-100 ppb levels on the order beat methods analysis. been applied to 10 different concentrates 8 commercial juices, showing fairly reproducibility detection level 2
