Abstract

Since Corona 19, awareness about antibacterial bacteria has changed. Hand washing after going out became a necessity. Also, fogging occurs a lot on the glasses depending on the wearing of the mask. This problem has caused a lot of discomfort in our daily life and changed our perception of antibacterial and anti-fogging. Therefore, in this study, we studied whether mugwort extract is effective in preventing antibacterial and fogging. To obtain the mugwort extract, mugwort was dried, alcohol extracted, and freeze-dried. An antibacterial test was performed using a mixture of mugwort extract, zinc oxide and natural zeolite mixed in 3:7, and a fogging test was performed using mugwort extract and other mixtures. As a result, in the case of E. coli and K. pneumoniae, which were used as test strains in the antibacterial test, the bacteria were not cultured from the medium added with 1% mugwort extract, and the antibacterial activity against representative Gram-negative bacteria was confirmed. In the anti-fog test, a 10 wt% mixture of mugwort extract showed very good results in both the hot and cold parts. We expect the mugwort extract to be effective in antibacterial and anti-fogging, thus helping to overcome Corona 19.

코로나 19 이후 향균에 대한 인식이 많아 달라졌다. 외출 후의 손세정은 필수사항이 되었다. 또한 마스크 착용에 따라 안경에 김서림이 많이 발생한다. 이 문제점은 지금까지의 일상생활에 많은 불편함을 야기하고, 향균과 김서림 방지에 대한 우리들의 인식을 바꾸게 하였다. 이에 본 연구에서는 쑥 추출물을 이용하여 향균 및 김서림 방지에 효과가 있는지 연구를 하였다. 쑥 추출물을 얻기 위해 쑥의 건조과정, 알코올 추출과정, 동결건조과정을 거쳤다. 쑥 추출물과 3:7로 혼합된 징크옥사이드, 천연제올라이트 혼합물을 사용하여 향균성 테스트를 실시하였으며, 쑥 추출물과 기타 혼합물을 사용하여 김서림 방지 테스트를 실시하였다. 그 결과 향균성 테스트에서 시험균주로 사용된 E. coli와 K. pneumoniae의 경우 갯쑥추출물 1% 첨가배지부터 세균이 배양되지 않아 대표적인 그람음성균에 대한 항균력이 확인되었다. 김서림 방지 테스트에서 쑥 추출물 10wt% 혼합물이 고온부와 저온부 모두 매우 양호한 결과를 나타냈다. 우리는 쑥 추출물이 향균과 김서림 방지에 효과가 있어 코로나 19를 극복하는데 많은 도움을 줄 것으로 기대한다.
