In this study, in order to find out the active ingredients of the hot water extract of cypress leaves, extracting by ratio of ethanol was analyzed, and antioxidant and antibacterial activity were investigated. In the measurement of chromaticity, as the ratio of ethanol in the cypress leaf extract increased, the yellowness decreased and the redness tended to increase. GC-MS component analysis confirmed the sesquiterpene-based component. In the antioxidant experiment of cypress leaf extract, compared with ascorbic acid, a control group, ethanol extracts of 50% or more showed higher antioxidant activity. In addition, it showed antibacterial activity of over 80% against Staphylococcus aureus strain, a food poisoning-causing bacterium, under all extraction conditions, and among them, 100% ethanol extract showed high antibacterial activity of 99.9%.
