Abstract
This study was carried out to investigate the biological activities of grass clippings from turfgrass including Zoysia japonica (TG-1), Zoysia matella (TG-2), Agrostis palustris (TG-3), and Poa pratensis (TG-4). The 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity was relatively higher in TG-1 and -2. Especially, TG-1 exerted the strongest hydroxyl radical scavenging effect, showing 90.40% at the concentration of 100 μg/ml. In addition, TG-1 inhibited the growth of Staphylococcus aureus, Escherichia coli and Helicobactor pylori. TG-1 also showed the highest inhibitory effect of AGS human gastric adenocarcinoma cell growth and nitric oxide production against lipopolysaccharide in RAW 264.7 macrophage cells. In conclusion, among the TG extracts, TG-1 has anti-oxidative, anti-microbial, anti-cancer and anti-inflammatory effect, indicating that TG-1 may be the potential source of functional food.
