Abstract: A method for preparing a natural phenolic epoxy resin is provided to obtain a phenolic epoxy resin useful as a solvent-free coating agent having excellent water resistance, acid resistance, alkali resistance and stability to an organic solvent. The method for preparing a natural phenolic epoxy resin comprises the steps of: forming an unsaturated double bond-containing phenolic polymer derived from plants; reacting an organic acid, hydrolase and hydrogen peroxide to form a peroxidized organic acid; and inserting oxygen atom into the unsaturated double bond of the plant-derived phenolic polymer by using the peroxidized organic acid. Particularly, the peroxidized organic acid is obtained by dissolving the phenolic polymer and the organic acid into an organic solvent, and introducing hydrolase and hydrogen peroxide thereto so that hydrogen peroxide is decomposed by hydrolase to provide oxygen, which, in turn, is bound to the organic acid.
