Fucoidan, extracted from Ecklonia cava, has been extensively studied because of its wide biological activities. However, antioxidative activities have not been yet examined. Therefore we evaluated in vitro and in vivo studies on antioxidative activities of E. cava fucoidan (ECF). ECF exhibited more prominent effects in peroxyl radical scavenging activity,(More)
Isolation of bioactive compounds and commercialization of marine microalgae sources are interesting targets in future marine biotechnology. Cultured biomass of the marine microalga, Nannochloropsis oculata, was used to purify angiotensin-I converting enzyme (ACE) inhibitory peptides using proteases including pepsin, trypsin, α-chymotrypsin, papain,(More)
In this study, we isolated and purified secondary metabolites from an edible brown seaweed, Undariopsis peterseniana, and evaluated their anti-inflammatory effects in vitro and in vivo. Apo-9′-fucoxanthinone (Apo-9′), a main anti-inflammatory compound found in the chloroform fraction of U. peterseniana extracts, was first isolated by one-step centrifugal(More)
A freshwater alga, Spirogyra sp., collected in shallow ponds in South Korea, was evaluated for its antilipid peroxidative effect against 2,2′-azobis (2-amidinopropane) dihydrochloride (AAPH)-induced in vivo zebrafish, and antioxidative compounds from the alga were efficiently identified using 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS+)(More)
