Abstract

In this study, we sought to confirm the potential of the Chaetomorpha torta extract as a raw material for cosmetics. Accordingly, we sought to find the optimal extraction conditions for Chaetomorpha torta by ethanol concentration and to check whether it has an anti-inflammatory effect by confirming the inhibitory effect of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6). The main contents of the experiment results are as follows. First, when DPPH radical scavenging ability and polyphenol yield were used as the criteria for optimal extraction conditions of Chaetomorpha torta, 70% concentration ethanol extract was most suitable. Second, as a result of cytotoxicity evaluation using Raw 264.7, no cytotoxicity was observed at concentrations below 100 ㎍/mL. Third, as a result of measuring the inhibitory effect of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in LPS-induced Raw 264.7 cells, the production of all cytokines decreased in proportion to the concentration, and 100 ㎍/mL It was confirmed that the concentrations were 73.76±2.6%, 84.8±2.42%, and 91.91±0.47%, respectively, showing excellent anti-inflammatory properties. According to these research results, it appears that the extract of the Chaetomorpha torta can be valuable as a raw material for cosmetics with anti-inflammatory properties, and if research on antioxidant, antibacterial, and anti-inflammatory activities related to green algae is conducted more actively, marine resources can be used as useful basic data. It is believed that it will be.

본 연구에서는 꼬불염주말 추출물이 화장품 원료 소재로서의 가능성을 확인하고자 하였다. 이에 에탄올 농도별 꼬불염주말의 최적추출조건을 찾고, 전염증성 사이토카인(TNF-α, IL-1β, IL-6)의 억제 효과를 확인하여 항염 효과가 있는지 살펴보고자 하였다. 실험 결과의 주요 내용은 다음과 같다. 첫째, 꼬불염주말의 최적추출조건 기준을 DPPH 라디칼 소거능과 폴리페놀 수율로 하였을 때, 70% 농도의 에탄올 추출물이 가장 적합하였다. 둘째, Raw 264.7을 이용한 세포 독성 평가를 진행한 결과, 100 ㎍/mL 이하의 농도에서는 세포 독성을 나타내지 않았다. 셋째, LPS로 유도된 Raw 264.7 세포에서 전염증성 사이토카인인 TNF-α, IL-1β, IL-6의 억제 효과를 측정한 결과, 모든 사이토카인 생성이 농도에 비례하게 감소하였으며, 100 ㎍/mL 농도에서 각각 73.76±2.6%, 84.8±2.42%, 91.91±0.47%를 보여 매우 뛰어난 항염능이 있음을 확인하였다. 이와 같은 연구 결과에 따라 꼬불염주말 추출물은 항염 특성을 가진 화장품 원료 소재로서 활용 가치가 있을 것으로 보이며, 녹조류와 관련된 항산화, 항균, 항염 활성 등에 관한 연구가 더 활발하게 이루어진다면 해양 자원의 유용한 기초 자료가 될 것으로 사료된다.
