Abstract

With the recent increase in health concerns, consumer needs for new health function materials have increased. Accordingly, physiological activity such as antibacterial and antioxidant effects of black garlic, black bellflower root, black deodeok, black ginseng, black leek, and pine powder, which have recently increased interest as a health functional material, was reviewed in this study. To examine the antibacterial activity of hot water extracts of each material, E. coli KCTC 2571, E. coli KCTC 1039, S. aureus KCTC 3881, S. aureus KCCM 1135, B. cereus KCCM 11204, L. monocytogenes KCCM 40307, P. aeruginoss KCTC 2513 were examined. The hot water extracts of black onion and black deodeok showed the growth inhibition of all the indicator strains except B. cereus KCCM 11204 and L. monocytogenes KCCM 40307. To examine the anti-oxidation activity of each material, the free radical scavenging test was used. The anti-oxidation activity of hot water extraction of each material was generally superior to that of 70% ethanol extract. And the hot water extracts of pine powder and the black bellflower root showed the excellent anti-oxidation activities, and are expected to be expected as new antioxidant materials.
