Antifungal activity of plant derived extracts against G. trabeum

While synthetic chemicals have provided excellent protection to woods used in adverse environments, the general public remains interested in naturally derived wood protectants. There are diverse arrays of possible candidates, but many of these compounds are not readily water soluble and efforts to render them soluble often reduce biological activity. In this report, we describe efforts to enhance water solubility of various plant extracts, while retaining activity against Gloeophyllum trabeum, a common wood decay fungus. The results suggest that polyvinylpyrrolidones have potential as co-solvents for many plant extracts.
