Sulfide derivatives of catechins derived from condensed tannins have broad spectrum biocidal characteristics. Epicatechin-4-alkylsulfides and cupric complexes thereof containing up to 20, preferably 5 to 15, carbon atoms are particularly effective biocides against wood rotting fungi and gram-positive bacteria. Such sulfides are prepared by reacting condensed tannin, either in the form of a purified tannin extract or comminuted plant tissue, with an appropriate thiol under mild acidic conditions.
