Abstract

|
The antimicrobial and antioxidative activities were investigated to confirm the utility of wood vinegar. Antimicrobial activity was performed by paper disc method and liquid culture. The growth inhibition was observed in all microbial species at a dose of as low as 25 m of wood vinegar by paper disc method. Also, in liquid culture, S. cerevisiae and P. aeruginosa were more inhibited the growth than others in the concentration of (v/v). For measuring of antioxidative activity, wood vinegar was fractionated with acidic, phenolic, basic and neutral fraction; and their antioxidant activities were measured by the radical scavenging effect on DPPH radical. In four fractions, phenolic fraction showed high antioxidative activity.
