Antioxidative activities of a mycosporine-like amino acid, porphyra-334

Antioxidative activities of porphyra-334, a mycosporine-like amino acid extracted from laver were evaluated. Oxidation of linoleic acid induced by an alkyl-radical 2,2′-azobis (2-amidinopropane) dihydrochloride (AAPH) was successfully suppressed by porphyra-334 (0–200 μM). The simultaneous applicati...

Description
Summary:Antioxidative activities of porphyra-334, a mycosporine-like amino acid extracted from laver were evaluated. Oxidation of linoleic acid induced by an alkyl-radical 2,2′-azobis (2-amidinopropane) dihydrochloride (AAPH) was successfully suppressed by porphyra-334 (0–200 μM). The simultaneous application of 0.02 μM α-tocopherol and 50 μM porphyra-334 effectively suppressed the AAPH induced oxidation level to approximately 40% of a single application of porphyra-334 after 10 min reaction. Porphyra-334 (0–200 μM) efficiently suppressed the lipid peroxidation induced by singlet oxygen although the antioxidative effect observed was relatively moderate at the initial stage of oxidation. These results suggested that porphyra-334 may function as an antioxidant which influences the storage stability of laver.
