The inconsistent methods of harvest, identification, and preparation of brown algae samples make it difficult to compare the results of certain measurements across different studies, such as total phenolic contents (TPC), total flavonoid contents (TFC), and total antioxidant capacities (TAC). Therefore, this study aims to systematically measure and compare TPC, TFC, and TAC in 10 types of standardized brown algae extracts provided by the Bio-Resource Information System of Korea. Among the ten brown algae extracts, Ishige foliacea exhibited the highest levels of TPC and TAC, followed by Sargassum nigrifolium. TAC was measured by the following four assays: ABTS, DPPH, superoxide radical scavenging activities, and ferric reducing antioxidant power. TAC was found to be positively correlated with TPC (p<0.05) but not TFC, indicating that Ishige foliacea and Sargassum nigrifolium have potential use as marine antioxidative food material.

본 연구는 해양자원정보시스템의 '해양갈조식물자원'에서 표준화된 갈조류 10종을 분양 받아 총 폴리페놀, 총 플라보노이드 및 총 항산화능력을 비교한 연구이다. 10종의 갈조류 중 총 폴리페놀이 높은 갈조류는 넓패, 개미역쇠, 그리고 검둥모자반이였으며, 이들 중 넓패와 검둥모자반은 총 플라보노이드 및 항산화능력도 다른 갈조류와 비교하여 유의적으로 높은 능력을 보였다. 또한, 총 폴리페놀 함량, 총 플라보노이드 함량, 총 항산화능력 간의 상관관계 조사를 통하여 총 플라보노이드보다 총 폴리페놀 함량이 해조류의 총 항산화능력에 연관성이 있음을 확인하였다. 이를 바탕으로 넓패 및 검둥모자반은 높은 총 폴리페놀 및 플라보노이드를 함유하는 갈조류 기능성 식품 소재로의 가능성을 보여주었다. 또한, 이 연구의 자료는 국내 자생하는 갈조류의 생리활성물질과 기능성연구에 기초자료로 활용이 가능할 것이다.
