Abstract Fusaric and 9,10-dehydrofusaric acids and their corresponding methyl esters were isolated from the culture filtrates of Fusarium nygamai . The methyl esters were characterized by chemical and spectroscopic methods and reported here for the first time as naturally occurring products. When assayed on tomato leaves and seedlings at 2.7 × 10 −3 and 2 × 10 −4 M, respectively, fusaric and 9,10-dehydrofusaric
摘要 从镰刀菌培养滤液中分离得到镰刀菌酸和9,10-脱氢镰刀菌酸及其相应的甲酯。甲酯通过化学和光谱方法进行表征,并首次作为天然产物在此报告。当分别在 2.7 × 10 -3 和 2 × 10 -4 M 的番茄叶片和幼苗上测定时,镰刀酸和 9,10-脱氢镰刀酸及其甲酯显示广泛的萎黄病迅速演变为坏死以及对根的强烈抑制伸长率,分别。当在盐水虾(卤虫)上以 10 -4 M 测定时,镰刀酸和 9,10-脱氢镰刀酸没有证明是有毒的,而它们的甲酯显示出 50% 的毒性水平,表示为死亡率。
