A dilute sulfuric acid solution or aqueous ammonia was dropwise added to the foregoing reaction solution for enzyme-activity determination from which the buffer is omitted (i.e., a solution comprising 50 μl of a 200 mM solution of eugenol in n-octane, 200 μl of a 50 mM aqueous solution of phenazine methosulfate and 675 μl of deionized water) to adjust the pH thereof from 5 to 7 and the resulting mixture is stirred at a temperature ranging from 25 to 55° C. for 15 to 180 minutes. After the completion of the reaction, the coniferyl alcohol is extracted from the reaction solution with an organic solvent such as ethyl acetate, chloroform, methylene chloride or ethyl ether, followed by purification thereof by a means such as silica gel chromatography, reverse phase liquid chromatography or vacuum distillation, optional discoloration with active carbon and vacuum drying to give colorless coniferyl alcohol powder.
