담색국화잎지의류 추출물의 폴리페놀, 플라보노이드 함량 및 항산화 활성 탐색

Abstract

Lichens are complex microorganisms in which fungi (mycobionts) and algae (photobionts) live in symbiosis by forming limbs. Most of the fungi that make up lichens, such as the Burleighi, are asymptomatic fungi, accounting for almost 99% of all known lichen species. In this study, polyphenol content, flavoid content, and antioxidant activity were investigated to inquire the possibility of Xanthoparmelia meximcana as a cosmetic material. Total polyphenol contents were calculated to be 500 μg/mL and four antioxidant assays whereas DPPH, ABTS, and hydroxyl radical scavenging were performed resulting in the range of 50-500 μg/mL (IC50). All four fractions showed no cytotoxicity up to the concentration of 100 μg/mL by MTT assay. The Xanthoparmelia meximcana would be a valuable asset for many applications, including cosmetic products.
