用高效液相色谱法发现病区小麦,玉米中存在非病区没有或极少检出的两种物质(1987)。翌年用气质联仪法确定其中之一为苏糖醇。1992年同样用此法确认了第二种物质为木糖醇。这两种多元醇均来源于土壤镰刀菌对病区谷物的污染,而且与病情之间呈现“剂量效应”联系。作者认为这两种多元醇的检出,作为镰刀菌污染程度指标,对于本病的病因流行病学研究具有重要价值。 High-performance liquid chromatography found that there were two substances in the diseased wheat and maize that were not detected or rarely detected in non-endemic areas (1987). The following year by GC-MS method to determine one of the threitol. In 1992, the same method was used to confirm that the second substance was xylitol. Both of these polyols originate from fusarium soil contamination of the ward and show a “dose-effect” relationship with the disease. The author believes that the detection of these two polyols, as Fusarium contamination level indicators, for the etiology of the disease epidemiological studies of great value.
