Abstract
A screening method has been developed for simultaneous determination of aflatoxin B1 and ochratoxin A in black olives. The technique includes extraction of both mycotoxins with aqueous methanol, cleanup using lead acetate, defatting with hexane, partitioning in chloroform, and thin layer chromatography. Detection limits are 5-7 micrograms aflatoxin B1 and 20 micrograms ochratoxin A/kg.
摘要
已开发出一种用于同时测定黑橄榄中黄曲霉毒素B1和赭曲霉毒素A的筛查方法。该技术包括用甲醇水溶液提取两种霉菌毒素，用醋酸铅净化，用己烷脱脂，在氯仿中分配，以及薄层色谱法。黄曲霉毒素B1的检测限为5 - 7微克，赭曲霉毒素A的检测限为20微克/千克。
