Identification and removal of aflatoxin coprecipitates derived from plant samples on immunoaffinity chromatographic purification

The non-polar compounds that coprecipitate with aflatoxins and interfere aflatoxin analysis using an immunoaffinity column (IAC) were identified and an effective pretreatment method was developed in combination with IAC. The proanthocyanidins fractionated from cinnamon coprecipitated with four major aflatoxins (B
