    Description

    The forest products industries of the southern United States harvest approximately 7 million dry tons of pine bark each year. This resource receives little utilization other than recovery of fuel values. approximately 2 million dry tons (30-40% of bark dry weight) of potentially valuable polyflavonoids are burned annually. Conifer bark flavonoids have potential industrial application in manufacture of antioxidants, pigments, adhesives, clay dispersants, grouting agents, water-soluble heavy-metal fertilizers, ion exchange resins, and additives for boiler water, and drilling muds [1]. As witnessed by the recent interest in finding substitutes for phenol, the commercial potential for silvichemicals is improving greatly.
