摘　　要：赭曲霉毒素A是由曲霉属和青霉属菌株产生的一种有毒真菌次级代谢产物。毒理学研究表明,赭曲霉毒素A具有很强的肝脏毒性和肾脏毒性,并有致畸、致突变和致癌作用。赭曲霉毒素A广泛存在于谷物及谷物产品、香料和咖啡豆等产品中,严重危害人类健康。许多国家建立了赭曲霉毒素A的限量标准,因此有必要研究准确、灵敏的赭曲霉毒素A的检测方法。综述了赭曲霉毒素A的理化性质及其检测分析方法的研究进展。Oehratoxin A （OTA） is a secondary fungal metabolite produced by several moulds, mainly by aAspergillus and penicillium. Toxicological studies indicated that ochratoxin A is a teratogenic, mutagenic and carcinogenic mycotoxin with the strong toxic effects on liver and kidney. OTA occurs predominantly in cereal grains, cecal products, spices, coffee beans and legumes. Ochratoxin A seriously threats human and animal healthy and life safety. Many countries set the permissible concentration of OTA in foodstuffs, so it is necessary to develop reliable and sensitive determination methods of ochratoxin A. Properties of OTA and methods for OTA analysis are reviewed.
