引言 禾谷镰刀菌(Fusarium graminearum Schw)是引致麦类、玉米等禾谷类作物赤霉病的主要病原物之一,它广布于欧、亚、北美和大洋洲等地。受该菌侵染的粮食作物,不但产量受到严重影响,且在谷物中残存有毒的代谢产物,人、畜误食这些粮食可引起头痛、头晕、呕吐、腹泻和中枢神经系统严重紊乱等中毒反应,Stands最早从污染的谷物中提取出致呕的赤霉菌代谢产物,证明了中毒的原因是一种毒素的作用。Bamburg首次进行了这种毒素的纯化工作,并于1968年正式定名为单端孢霉烯族化合物(trichoth-
Introduction Fusarium graminearum Schw is one of the major pathogen causing scab in cereal crops such as wheat and corn. It is widely distributed in Europe, Asia, North America and Oceania. Food crops infected with the bacteria not only have a serious impact on the yield but also contain toxic metabolites in cereals. People and livestock who eat these foods can cause poisoning such as headache, dizziness, vomiting, diarrhea and severe central nervous system disorders , Stands earliest from the contaminated grains extracted gnats gibberellin metabolites, to prove the reason of poisoning is a toxin role. Bamburg first performed this purification of the toxin and officially became known in 1968 as trichoth-
