中文摘要：本研究报道了尼日利亚五个农业生态区生产的稻米中真菌种类及真菌代谢物的分布情况。采用稀释平板法分离菌株，并用适当的诊断方法鉴定；代谢物检测采用液相色谱-串联质谱法。结果发现，稻米中真菌主要为曲霉和青霉，而没有分离到镰刀菌。这些地区所产的大米中平均真菌计数差异显著。根据真菌代谢物的浓度及分布， 构建了16种真菌代谢物的发生图。最高水平的真菌代谢物污染发生在北部几内亚萨凡纳区，而苏丹萨凡纳区最低。
外文摘要：This study reports the distribution of fungal isolates and fungal metabolites that naturally contaminate locally processed rice from five agro-ecological zones of Nigeria. The fungal species were isolated by the dilution plate technique and identified by appropriate diagnostics, while metabolites were determined by a liquid chromatographic tandem mass spectrometric method. Aspergillus and Penicillium species were the predominant isolates found in the rice samples while Fusarium spp. were not isolated. The mean fungal count differed significantly (p 2 cfu g−1 in the Southern Guinea Savannah to 96.97 × 102 cfu g−1 in the Derived Savannah. For 16 fungal metabolites, selected from 63 positively identified fungal metabolites based on their concentration and spread across the zones, an occurrence map was constructed. The Northern Guinea Savannah recorded the highest contamination of fungal metabolites while the Sudan Savannah zone recorded the least.
