Abstract

A sensitive LC-electrospray positive ionization (ESI+) MS/MS method was developed and validated for the determination of the Aspergillus mycotoxin, sterigmatocystin, in grains at levels down to less than 0.5 microg/kg. Recovery was found to be greater than 97% for wheat grains.

摘要

开发并验证了一种灵敏的液相色谱-电喷雾正离子（ESI+）串联质谱法，用于测定谷物中曲霉属霉菌毒素——黄曲霉毒素前体，其检测限低至0.5微克/千克以下。发现该方法对小麦籽粒的回收率大于97%。
