Phenol in Quackgrass Associated with Dalapon

An unknown compound isolated chromatographically from extracts of rhizome tissues of quackgrass which had previously been treated with dalapon resembled phenol. The compound reduced silver nitrate and had an ultraviolet absorption maximum similar to that of phenol and a positive reaction to the LeRosen test. Melting points and infrared absorption maxima for phenylurethane and agr-naphthylurethane derivatives of the unknown matched those for the same phenol derivatives.
