从菠菜（Spinacia oleracea）根中分离到一种对菠菜根腐病病原菌螺旋丝囊霉（Aphanomycescochlioides）游动孢子有很强引诱作用的物质，经光谱和化学合成鉴定其结构为螺旋丝囊霉素A（5-hydroxy-6，7-methylenedioxyflavone，1）。通过浸泡在1的溶液中制备的chromosorb颗粒显示出对游动孢子的有效吸引活性，使用浓度高于10 - 9或10 - 10 M的1。
A highly potent attractant of zoospores ofAphanomyces cochlioides, a causal fungus of the root rot disease of spinach (Spinacia oleracea), was isolated from spinach roots, and its structure was determined by spectroscopic evidence and chemical synthesis as cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone,1). A chromosorb particle prepared by soaking in solution of1 showed a potent attracting activity toward the zoospores using concentrations of1 above 10−9 or 10−10 M.
