dimethoxyphenol was a widely used substrate in determination of laccases activity. It was surprised, however, that the products of it had not been completely determined until now. Studies were thus conducted on Rhus laccase （RL） and immobilized Rhus laccase （IRL）-catalyzed oxidation of 2,6-dimethoxyphenol （DMP） in water-organic solvent systems. Only one product, 3,3′,5,5′- tetramethoxy-1 ,1′-biphenyl-4,4′-diol （TMBP）, was produced by RL catalysis, and it was thoroughly characterized by FT-IR, NMR and GC-MS, etc.

Wood vinegar(WV)has a powerful antioxidant activity,but it is unclear which components are responsible for the antioxidant *** the present study,the double-column retention index qualitative method was used for the identification of the major components in five kinds of W7 And the major antioxidants of wood vinegar were accurately identified with the aid of Pearson product-moment correlation coefficients and authentic standard samples. Our results demonstrate that phenolic compounds are mainly responsible for the powerful antioxidant activity. 2,6-dimethoxyphenol is the most powerful antioxidant in WV.2-Methoxyphenol and 3-methyl-1,2-cyclopentanedioue also have an important influence on the antioxidant activity of *** results suggest that the contents of 2-methoxyphenol,2,6-dimethoxyphenol and 3-methyl-1,2-cyclopentanedione should act as the criteria for evaluating the antioxidant activity of *** work will provide useful information for WV's application in the fields of food and medicine as antioxidants.
