摘要: GC with electron capture detection has been applied for the determination of deoxynivalenol (DON) in medicinal herbs and related products. The method consists of extracting the sample with water followed by clean-up of the resulting extract with an immunoaffinity column. DON was determined as its heptofluorobuturyl ester. Positive results were further confirmed by GC-MS. Recoveries from different medicinal herbs spiked with DON at levels ranging from 100 to 5,000 mu g kg(-1) were from 85.5 to 97.2%, with relative standard deviations (RSDs) being less than 6.3%. The limit of detection was 2.0 mu g kg(-1). Out of a total of 58 samples, DON was only found at low concentrations in three samples, ranging from 17.2 to 50.5 mu g kg(-1). This is the first report of DON determination and contamination in medicinal herbs and related products in China.
