Although many studies were performed to develope natural sanitizers replacing chemical sanitizers against foodborne viruses, the investigations for woody plant sprout extracts were rare. In this study, the antiviral activities of woody plant sprout extracts against feline calicivirus (FCV) and murine norovirus (MNV) as a surrogates for norovirus were evaluated. Antibacterial activity against gram-positive bacteria and functional ingredients were also analyzed. Antiviral activity tests were followed by 50% tissue culture infectious dose (TCID50) and antibacterial activity tests were followed by paper disc agar diffusion. Among woody plant sprout extracts of 9 species, extract of Salix spp. showed significantly high antiviral activity against FCV and MNV. After the treatment of Salix spp. ethanol extract (0.1 mg/mL) for 3 hour, MNV and FCV was completely inactivated. Sodium hypochlorite showed higher antiviral activity against FCV and MNV than Salix spp. extract. Alnus japonica sprout. showed the highest antibacterial activity. Alnus japonica sprout extracts had strong antibacterial activities against most of Gram(+) bacteria but did not show antibacterial activities against of Gram(-) bacteria. Total polyphenol, and flavonoid contents, DPPH and ABTS free radical scavenging activities of ethanol extract were higher than that of distilled water extract. Camelia Japonica L, extract showed the highest α-glucosidase inhibitory activity as 92.07%. and Salix spp. extract showed the highest α-amylase inhibitory activity as 78.43%. This study showed an application possibility of woody plant sprout extract as natural sanitizer.
