Abstract:
Soil-cultivation presents environmental limitations and requires considerable labor, space, and water supply. Alternatively, hydroponically-cultured ginseng (HG) was improved its productivity, availability, and functionality. Improvement of bio-functionality by probiotic fermentation also has been studied. Therefore, in this study, HG was fermented using probiotics to enhance antioxidant and anti-inflammatory activities. Soil-cultivated ginseng (SG), 1 and 2-year HG (HG1, HG2) were extracted using 70% ethanol and fermented by Lactobacillus brevis B7. After fermentation, the phenolic and flavonoid contents, and antioxidant and NO scavenging activities were increased, and HG showed higher bioactivities than SG. Particularly, fermented HG2 showed the highest antioxidant and anti-inflammatory activities and significantly decreased the level of inflammatory mediators. Furthermore, fermented HG2 also effectively inhibited NF-κB signaling pathway. These results suggested that fermented HG significantly enhanced functionality compared to SG and non-fermented HG. This suggests that fermented HG is a potentially useful ingredient for developing health-functional foods or pharmaceutical materials.
