  • Three active compounds were isolated from the culture of a plant pathogenic fungus, Bipolaris cynodontis. The structure elucidation of these compounds was accomplished by 2D NMR techniques, such as $^1H-^1H$ and $^{13}C-^1H$ COSY, COLOC, HMBC and rotating frame NOE(ROESY). Compounds were found as derivatives of cochlioquinone and cochlioquinol that were previously isolated as phytotoxins from B. bicolor and B. cynodontis, respectively. The compounds showed phytotxicity against Italian ryegrass, one of the host plants of B. cynodontis.
