Introduction Foliage is the factory of chemical processes leading to the growth of a plant. The number of chemicals which can be derived from foliage is numerous.Thus, foliage offers a large potential raw material source for industrial use due to its valuable silvichemicals (Barton 1976, 1978, 1981; Keays 1976). Phenolic and other compounds contained in foliage have a simpler and smaller molecular structure than other wood constituents. Therefore, low molecular weight foliage compounds may possess great potential for use as phenol substitutes in phenol formaldehyde resins. Chow (1977) reported foliage exhibited good adhesive properties for bonding particleboards. Barton et al. (1978) also successfully used foliage as a substitute for wheat flour and conventional fillers in plywood glue mixes. As reported previously (Chen 1991), several phenolic copoiymer resins made of tree foliage extracts have been developed for gluing exterior grade structural plywood. The copoiymer resins, with a 40 percent weight replacement of phenol by tree foliage extracts, proved to have shorter press time requirements than commercial phenol formaldehyde resin, based on standard plywood glueline evaluation (Chen 1991), and flakeboards and composite panel properties (Chen 1992). Of particular interest is the fact that the copoiymer resins containing tree foliage extracts
