Última Antioxidant properties of some filamentous green algae (Chaetomorpha Genus) BABT Farasat,Massoumeh; Khavari-Nejad,Ramazan-Ali; Nabavi,Seyed Mohammad Bagher; Namjooyan,Foroogh. The antioxidant activity and the contents of total phenolics and flavonoids were quantified in the methanolic extracts of four Chaetomorpha species including C. aerea, C. crassa, C. linum and C. brachygona. Eight samples of Chaetomorpha plants were collected from five locations along the northern coasts of the Persian Gulf in south of Iran from December 2010 until October 2011. Methanolic extracts of the seaweeds were assessed for their antioxidant activity using DPPH radical scavenging assay. C. linum showed highest antioxidant potential with a relatively low IC50 (1.484 ± 0.168 mg mL-1), the highest flavonoid content (18.177 ± 2.238 mg RE g-1 ) and a relatively high content of phenolics (2.895 ± 0.415 mg GAE g-1) in comparison with the other species.

Abstract Melanogenesis is a biological process which led to the synthesis of melanin pigment. Abnormal melanin production results in melasma, solar lentigo, post inflammatory melanoderma, etc. In this study, we examined the potential inhibitory effects of 17 brown macroalgae from Persian Gulf on melanogenesis. The effects of various concentrations (100, 250 and 500 µg/mL) of methanolic extracts of macroalgae belonging to four genera (including: Padina, Colpomonia, Cystoseira and Sargassum) were studied on oxidation of L-Dopa by mushroom tyrosinase. Subsequently, the activity of macroalgae with high inhibitory effect on monophenolase activity of mushroom tyrosinase and zebrafish was investigated using L-tyrosine as a substrate. Anti-melanogenesis effects of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Algae; Persian Gulf; Melanogenesis; Mushroom tyrosinase; Zebrafish.
