In this study, antibacterial activity against pathogenic strains and antioxidant activity were measured using the red pine leaf distilled concentrate. The results of the antibacterial activity measured using an emulsion of the red pine leaf distilled concentrate by the paper disc method showed the antibacterial activities against three Gram negative pathogenic strains, E. coli, S. typhi and Vibrio parahaemolyticus and exhibited growth inhibitions of 12 mm, 10 mm and 9 mm at a 5.0% (v/v) concentration, respectively. In addition, all three strains also showed growth inhibitions even at 0.5% (v/v) concentration. However, no antibacterial activity was exhibited against gram positive bacteria. The results of the antibacterial activity using the red pine leaf distilled concentrate measured by the turbidity method, the same antibacterial activities against three gram negative pathogenic strains, E. coli, S. typhi and V. parahaemolyticus as results of the paper disc method. V. parahaemolyticus showed more than 50% growth inhibition compared to the negative control at a concentration of 5% (v/v), E. coli exhibited 33.5% growth inhibition at 4 hr incubation, and S. typhi showed 65.1% and 44.6% growth inhibitions at 4 and 5 hr incubations, respectively. Antioxidant activities of an emulsion of the red pine leaf distilled concentrate were measured by DPPH and ABTS methods. DPPH method showed the highest activity of 55.81% at a 1.0% (v/v) concentration. ABTS method exhibited the highest activity of 18.44% at a 1.0% (v/v) concentration. Through this study, it is expected that the developments of the food and the cosmetics with enhanced functionality by utilizing the antioxidant and antibacterial activities of the red pine leaf distilled concentrate.
