바위꽃탱자나무지의류 추출물의 항산화 활성 및 염모제 소재 탐색

Abstract

Lichen refers to a group of organisms in which two organisms, an alga and a fungus, live together as a single organism. Algae photosynthesize and supply sugars to fungi, and fungi provide a place to live and inorganic nutrients for the algae. In this study, antioxidant activity, polyphenol content, and flavonoid content were investigated to determine the possibility of using extracts of Ramalina yasudae Rasanen as a hair cosmetic material. DPPH and ABTS radical antioxidant assays were performed and the results showed a range of 50-500 μg/mL (IC50). In the ABTS assay results for R. yasudae the IC50 values were confirmed to be 399 μg/mL for the water extract, 371 μg/mL for the methanol extract, and 250 μg/mL for the alkali extract. In an MTT assay, the R. yasudae alkali extract showed no cytotoxicity up to a concentration of 500 μg/mL. Accordingly, the R. yasudae extracts have the potential to be useful material for cosmetics and edible food.
