大麦产于全北、全南、庆北和庆南四个道，玉米主要产于韩国的江原道。对来自不同地区的39份大麦和46份玉米样品进行了镰刀菌毒素的自然发生情况调查。大麦中检测到5种8-酮基二萜类化合物，即脱氧雪腐镰刀菌烯醇（DON）、雪腐镰刀菌烯醇（NIV）、4-乙酰雪腐镰刀菌烯醇（4-ANIV）、3-乙酰脱氧雪腐镰刀菌烯醇（3-ADON）、4，15-二乙酰雪腐镰刀菌烯醇（4，15-DANIV）和玉米赤霉烯酮（ZEA）。DON、NIV和ZEA是大麦中的主要污染物，平均水平分别为170、1，011和287 ng/g。另一方面，在玉米样品中检测到DON、15-乙酰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，平均水平分别为310和297 ng/g。结果表明，单乙酰DON在两种谷物中的自然存在量和NIV/DON的比值不同。此外，这也是首次报道4，15-DANIV在谷物中的自然发生。
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.
