抄録

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 μg/g fresh weight. A new isoflavone, cristatein (5-hydroxy-6-hydroxymethyl-7,2′-dimethoxyisoflavone, 2), and five known flavonoids were also identified.
