RESUMO
In the processes of planting, harvest, transport and storage, improper treatment of Chinese materia medica (CMM) and foodstuffs and agricultural products will result in fungal growth and mycotoxins contamination, which will not only directly affect the quality, safety and efficacy of these complex matrices, but also seriously threaten the consumers' health and lives. Therefore, the establishment of high-throughout analytical methods with high sensitivity for the determination of mycotoxins in CMM and foodstuffs and agricultural products at trace levels will provide reliable references for reducing the risk of mycotoxin exposure in humans. Due to the matrix complexity of CMM and foodstuffs and agricultural products, highly-effective pretreatment technologies are necessary for the establishment of such analytical techniques. In this review, the current extraction and purification methods commonly used for the detection of mycotoxins were summarized, the importance of pretreatment techniques for the precise quantification of mycotoxins in complex matrices such as Chinese herbal medicines was highlighted, as well as the development tendency about the pretreatment techniques for mycotoxins in complex matrices in the future was proposed.
