Abstract
In this research, extracts were extracted at an ethanol ratio to find out the active ingredients with the effect of removing 2-nonenal, which is the cause of senile body odor, of the hot water extract of Chamaecypar is Obtusa Leaf. Also, the component analysis, antioxidant capacity, polyphenol and flavonoid quantitative analysis, antimicrobial activity and 2-nonenal removal efficiency were investigated. In the measurement of chromaticity, the higher the ethanol ratio in the Chamaecyparis Obtusa Leaf extract, the more the yellowness decreased and the redness increased. GC-MS component analysis showed the active ingredient of sesquiterpene group. LC-MS quantitative analysis showed a high polyphenol content in 40% ethanol extract. In the antioxidant experiment of Chamaecypar is Obtusa Leaf extract, more than 50 % of the ethanol extract showed higher antioxidant activity than the as coribic acid control. It showed more than 80 % antimicrobial activity against Staphylococcus aureus strain, a food poisoning-causing bacterium, under all extraction conditions. Among them, 100 % ethanol extract showed high antimicrobial activity of 99.9 %. In addition, the highest 2-Nonenal removal efficacy was investigated in the ethanol 40 % extraction.
