Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone, 1), known as a host-specific attractant towards the zoospores of Aphanomyces cochlioides, a cause of root rot and damping-off diseases of Chenopodiaceae, was found in the Amaranthaceae plant, Celosia cristata, that is susceptible to the pathogen. The content of 1 in Celosia seedlings was quantified as 1.4 microg/g fresh weight. A new isoflavone, cristatein (5-hydroxy-6-hydroxymethyl-7,2'-dimethoxyisoflavone, 2), and five known flavonoids were also identified.
旋花茄素A（5-羟基-6,7-亚甲二氧基黄酮，1）是一种对旋花腐霉游动孢子具有宿主特异性的引诱剂，旋花腐霉是藜科植物根腐病和猝倒病的病原菌，在易受该病原菌侵染的苋科植物鸡冠花中被发现。鸡冠花幼苗中1的含量经定量为1.4微克/克鲜重。还鉴定出一种新的异黄酮，鸡冠花素（5-羟基-6-羟甲基-7,2'-二甲氧基异黄酮，2）和五种已知的黄酮类化合物。
