Abstract:Besides in nonaqueous enzymo logy,po lypheno loxidase can a lso be used in analy tical chemistry as the enzy me electrode to identify pheno ls and cyanide,etc.The poly pheno loxidase inhibito rs are w idely used in industries o f cosmo tics a nd fo od.Po lyphenoloxidase can change L-tyro sin into L-Do PA,a routine m edicine fo r Pakinson’s disease.Ty roso nase has the cha racter of or tho-hydrox ylatio n on benzene ring,so it has g rea t sig nificance in o rganic synthesis.Owing to its impo rta nce in medicine,the cata lytic conv er-sio ns of p-creso l to4-methyl catechol and ca techols to4-methy l-1,2-benzoquinone w ere intensively stud-ied.In this w ork,w e used a chemical metho d to reduce4-methy l-1,2-benzo quinone to4-methyl ca techol, and to optimize the reactio n co nditio ns o f catecho l sy nthesis ca taly zed by immobilized enzyme.The yield of 4-methyl catecho l cataly zed by immo bilized enzyme is55.8%.

Key words:Nonaqueous media;Poly phenolo xida se;4-Methy l catecho l
