Antimicrobial effect of phlorotannins from marine brown algae

Food and Chemical Toxicology, 2012
Marine organisms exhibit a rich chemical content that possess unique structural features as compared to terrestrial metabolites. Among marine resources, marine algae are a rich source of chemically diverse compounds with the possibility of their potential use as a novel class of artificial food ingredients and antimicrobial agents.

Characterization of Phlorotannins from Brown Algae by LC-HRMS

2015
Phlorotannins are a class of polyphenols found in brown seaweeds that have significant potential for use as therapeutics, owing to their wide range of bioactivities. Molecular characterization of phlorotannin-enriched extracts is challenging due to the extreme sample complexity and the wide range of molecular weights observed.

Allocation Patterns of Phlorotannins in Antarctic Brown Algae

Phycologia, 2007
Abstract Brown algae from tropical and temperate regions of the world's oceans have been shown to contain phlorotannins as typical primary and secondary metabolites. Here, phlorotannin contents of nine abundant Antarctic brown algal species were determined, which ranged between 0.5 and 9% DW.

Sulphated phlorotannins from the brown algaPleurophycus gardneri

Phytochemistry, 1992
Abstract Eight phlorotannins were isolated and identified from an aqueous extract of the Pacific brown alga Pleurophycus gardneri . All compounds are composed of one or two phloroglucinol units, and six of them are conjugated with at least one sulphate group.

Antioxidant activities of crude phlorotannins from Sargassum hemiphyllum

Journal of Huazhong University of Science and Technology [Medical Sciences], 2016
Brown algae are well known as a source of biologically active compounds, especially those having antioxidant activities, such as phlorotannins. In this study we examined the antioxidant activities of crude phlorotannins extracts (CPEs) obtained from Sargassum hemiphyllum (SH) and fractionated according to the molecular weights.

Medicinal Effects of Phlorotannins from Marine Brown Algae

2011
Brown seaweeds are popular and abundant food in East Asia and also well known for their medicinal effects due to presence of active phenolic constituents. Phlorotannins, the major phenolic group of brown algae, have extensively investigated for their vast array of bioactivities such as antioxidant, anti-inflammatory, anticancer, and antidiabetic.

Stimulating phlorotannin production in seaweed

This thesis aims to determine the abiotic factors influencing the phenolic content of the intertidal species Fucus serratus, then stimulate and maximise phenolic synthesis under controlled laboratory conditions for application in seaweed nurseries.
