Abstract

Eighteen corn samples collected from Thailand were analysed for fumonisins and aflatoxins by high performance liquid chromatography. Fumonisins B1 and B2 were detected in 16 (89%) and 12 (67%) samples at levels ranging from 63 to 18800 ng/g (mean, 1790 ng/g) and from 50 to 1400 ng/g (mean, 251 ng/g), respectively. Fusarium moniliforme and F. proliferatum isolated from Thai corn showed the production of fumonisins in corn grit cultures. Aflatoxins B1 and B2 were found in 15 and 10 samples at mean levels of 72 and 15 ng/g, respectively. It was noted that as many as 72.2% (13/18) of samples were coincidentally contaminated with fumonisins and aflatoxins. Based on these results, the interaction of fumonisin-producers and aflatoxin-producers on kernel infection and contamination of these mycotoxins in corn is discussed. This is the first report on the natural co-occurrence of fumonisins and aflatoxins in Thailand.

摘要

采用高效液相色谱法对从泰国采集的18份玉米样本进行了伏马菌素和黄曲霉毒素分析。在16份（89%）样本中检测到伏马菌素B1，含量范围为63至18800 ng/g（平均1790 ng/g）；在12份（67%）样本中检测到伏马菌素B2，含量范围为50至1400 ng/g（平均251 ng/g）。从泰国玉米中分离出的串珠镰刀菌和层出镰刀菌在玉米碎粒培养物中表现出产生伏马菌素的能力。在15份样本中检测到黄曲霉毒素B1，平均含量为72 ng/g；在10份样本中检测到黄曲霉毒素B2，平均含量为15 ng/g。值得注意的是，多达72.2%（13/18）的样本同时受到伏马菌素和黄曲霉毒素的污染。基于这些结果，讨论了伏马菌素产生菌和黄曲霉毒素产生菌在玉米籽粒感染和这些霉菌毒素污染方面的相互作用。这是泰国关于伏马菌素和黄曲霉毒素自然共存的首次报告。
