Abstract

In this study, the antioxidant ability, anti-inflammatory ability and whitening effect of the extracted Grateloupia filicina under optimal conditions were confirmed. The useful substances of Grateloupia filicina were extracted with various ethanol aqueous solutions to measure DPPH, ABTS, and nitrite radical elimination capabilities, and the polyphenol and flavonoid contents were analyzed. When extracted with a 20% ethanol aqueous solution, the radical elimination ability was the best, and the content of polyphenol and flavonoids was also the highest. From this, it was confirmed that the 20% ethanol aqueous solution efficiently extracted the antioxidant and anti-inflammatory substances of Grateloupia filicina. Meanwhile, the cytotoxicity and anti-inflammatory properties of the Grateloupia filicina extract were confirmed using RAW 264.7 cell lines. Grateloupia filicina extract did not show toxicity at a concentration of 200 ㎍/mL, and showed NO production inhibitory capacity of 50% or more at this concentration. As a result, it was confirmed that the Grateloupia filicina extract can be used as a functional cosmetic raw material having antioxidant and anti-inflammatory properties.

본 연구에서는 최적의 조건에서 추출된 지누아리 추출물의 항산화능과 항염능을 확인하였다. 다양한 ethanol 수용액으로 지누아리의 유용물질을 추출하여 DPPH, ABTS, nitrite 라디컬 소거능을 측정하고, 폴리페놀 및 플라보노이드 함량을 분석하였다. 20% ethanol 수용액으로 추출한 경우에 라디컬 소거능이 가장 우수하였고, 폴리페놀과 플라보노이드의 함량 또한 가장 높았다. 이로부터 20% ethanol 수용액이 지누아리의 항산화 및 항염 물질을 효율적으로 추출하였음을 확인하였다. 한편, RAW 264.7 세포주를 이용하여 지누아리 추출물의 세포독성과 항염능을 확인하였다. 지누아리 추출물은 200 ㎍/mL의 농도에서 독성을 나타내지 않았고, 이 농도에서 50% 이상의 NO 생성 억제능을 나타냈다. 이러한 결과로 지누아리 추출물은 항산화 및 항염 특성을 지니는 기능성 화장품 원료로 사용 가능함을 확인하였다.
