概要

• 論文の詳細を見る

• Two host-specific phytotoxic metabolites, AK-toxin I and II, were isolated from a culture broth of Alternaria alternata Japanese pear pathotype, the fungus causing black spot disease of susceptible Japanese pear cultivars. From chemical, spectral and X-ray crystallographic data, AK-toxin I was characterized as 8-[(2S, 3S)-2-acetylamino-3-methyl-3-phenyl-propionyloxy](8R, 9S)-9, 10-epoxy-9-methyl-deca-(2E, 4Z, 6E)-trienoic acid. The structure of AK-toxin II was also assigned to be 3-demethyl derivative of AK-toxin I by comparing the spectral data with those of AK-toxin I.
