Ethyl acetate-soluble fractions were prepared from hot both red maple and sugar maple. These phenols were water extracts of 10-g samples of clear, discolored, and absent from discolored and decayed tissue. Total phenols decayed tissue of sugar maple, Acer saccharum, and red in clear red maple woody tissues were the same at the maple, A. rubrum. Extracts were chromatographed in two cambium and at the pith. The processes of discoloration dimension cellulose thin-layer chromatography plates and

The low level of acid:0.03% sodium acetate. Total phenols were deterphenols in discolored wood may permit the growth of mined by the Folin-Ciocalteu method on methanol decay fungi unable to grow at the phenol concentration extracts of clear red maple tissue. Gallic acid and catechin occurring in clear tissue. were identified as the major phenols in clear tissue of Phytopathology 63:167-169 Additional key words: Fomes connatus, Phialophora melinii, succession of microorganisms.
