Abstract

o-Nitrophenol derivatives have been isolated from the culture liquid of the deuteromycete Pyricularia oryzae Cav.: 4-hydroxy-3-nitrophenylacetic acid, 4-hydroxy-3-nitrobenzyl alcohol, 1- and 2-(4-hydroxy-3-nitrophenyl)ethanols, N-(4-hydroxy-3-nitrophenylethyl)acetamide, and pyriculamide. This is the first time that any of these compounds has been isolated from natural sources. The o-nitrophenols obtained possess moderate growth-inhibiting activity in relation to rice shoots.
