中文摘要：本研究旨在评估埃塞俄比亚东部花生粒和花生饼中的主要曲霉种类和黄曲霉毒素。从花生中分离的真菌看，黄曲霉是仅次于寄生曲霉的主要种类。用超高效液相色谱法分析样品中的黄曲霉毒素，发现以黄曲霉毒素B1为主。研究结果确认了埃塞俄比亚花生产品的高污染情况。
外文摘要：This study was conducted to assess major Aspergillus species and aflatoxins associated with groundnut seeds and cake in Eastern Ethiopia and evaluate growers' management practices. A total of 160 groundnut seed samples from farmers' stores and 50 groundnut cake samples from cafe and restaurants were collected. Fungal isolation was done from groundnut seed samples. Aspergillus flavus was the dominant species followed by Aspergillus parasiticus. Aflatoxin analyses of groundnut seed samples were performed using ultra performance liquid chromatography; 22.5% and 41.3% of samples were positive, with total aflatoxin concentrations of 786 and 3135 ng g-1 from 2013/2014 and 2014/2015 samples, respectively. The level of specific aflatoxin concentration varied between 0.1 and 2526 ng g-1 for B2 and B1, respectively. Among contaminated samples of groundnut cake, 68% exhibited aflatoxin concentration below 20 ng g-1, while as high as 158 ng g-1 aflatoxin B1 was recorded. The study confirms high contamination of groundnut products in East Ethiopia.
