Barley is produced in four provinces, Chonbuk, Chonnam, Kyungbuk, and Kyungnam, and corn is mainly produced in the Kangwon province in Korea. The natural occurrence of Fusarium mycotoxins was surveyed in 39 barley and 46 corn samples from different areas. Five 8-ketotrichothecenes, namely deoxynivalenol (DON), nivalenol (NIV), 4-acetylnivalenol (4-ANIV), 3-acetyldeoxynivalenol (3-ADON), and 4,15-diacetylnivalenol (4,15-DANIV), and zearalenone (ZEA) were detected in barley. DON, NIV, and ZEA were the major contaminants in barley, with mean levels of 170, 1,011, and 287 ng/g, respectively. On the other hand, DON, 15-acetyldeoxynivalenol (15-ADON), NIV, 4-ANIV, 4,15-DANIV, and ZEA were detected in corn samples. DON and 15-ADON were the major contaminants in corn, with mean levels of 310 and 297 ng/g, respectively. The survey indicated that the natural occurrence of monoacetyl-DON and the ratios of NIV to DON in two cereals were different. In addition, this is the first report of the natural occurrence of 4,15-DANIV in cereals.
大麦产于全北、全南、庆北和庆南四个省份，而玉米主要产于韩国的江原道。对来自不同地区的39份大麦样本和46份玉米样本中镰刀菌霉菌毒素的自然发生情况进行了调查。在大麦中检测到了五种8-酮单端孢霉烯族毒素，即脱氧雪腐镰刀菌烯醇（DON）、雪腐镰刀菌烯醇（NIV）、4-乙酰基雪腐镰刀菌烯醇（4-ANIV）、3-乙酰基脱氧雪腐镰刀菌烯醇（3-ADON）和4,15-二乙酰基脱氧雪腐镰刀菌烯醇（4,15-DANIV），以及玉米赤霉烯酮（ZEA）。DON、NIV和ZEA是大麦中的主要污染物，平均含量分别为170、1011和287 ng/g。另一方面，在玉米样本中检测到了DON、15-乙酰基脱氧雪腐镰刀菌烯醇（15-ADON）、NIV、4-ANIV、4,15-DANIV和ZEA。DON和15-ADON是玉米中的主要污染物，平均含量分别为310和297 ng/g。该调查表明，两种谷物中单一乙酰基-DON的自然发生率以及NIV与DON的比例有所不同。此外，这是关于谷物中自然发生4,15-DANIV的首次报告。
