Antioxidant effects and antimicrobial activites of phytoncide.

Physiological activities of four types of phytoncide solutions (A, AB, CY and D-types), prepared from various plants widely distributed in nature, were examined. We assayed these phytoncide solutions, testing for active oxygen inhibition, DPPH radical scavenging effects, nitrogen monoxide inhibition, and lipid peroxide inhibition. The AB- and D-types of phytoncide solutions especially showed comparably potent antioxidant effects. Antibacterial and antifungal assays were conducted using the AB- and D-types, with results showing significant inhibitory activities with these solutions.
