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.

Safety evaluation and effects of dietary phlorotannins on the growth, health, and intestinal microbiota of Litopenaeus vannamei.

Fish and Shellfish Immunology
Phlorotannins are phenolic compounds with diverse biological activities, yet their efficacy in aquatic animals currently remains unclear. This investigation scrutinized the influence of phlorotannins on the growth, immunity, antioxidant capacity, and ...

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.

The New Products from Brown Seaweeds: Fucoxanthin and Phlorotannins

2022
The brown seaweed industry has been established to produce three major traditional products including alginate, mannitol and iodine, however, is facing challenges to expand more product profiles. The innovation of the brown seaweed industry has been extended to minor bioactive compounds, such as fucoxanthin and phlorotannins, by using integrated ...

Phlorotannins in Ecklonia cava extract inhibit matrix metalloproteinase activity

Life Sciences, 2006
Matrix metalloproteinase (MMP) inhibitors have been identified as potential therapeutic candidates for metastasis, arthritis, chronic inflammation and wrinkle formation. For the first time here we report a detailed study on the inhibitory effects of phlorotannins in brown algae, Ecklonia cava (EC) on MMP activities in cultured human cell lines. A novel

Phlorotannins from the brown alga Cystophora torulosa

Phytochemistry, 1997
Abstract A number of phlorotannins were isolated at their peracetyl derivatives and identified by means of spectral analysis. The new compounds belong to the class of hydroxylated branched fucophlorethols and bisfucophlorethols lacking a 1,2,3-triphenoxy-5-acetoxybenzene moiety.

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.

Nutritional Significance of seaweed phlorotannins

Polyphenols, which are bioactive substances produced through acetate malonate pathway are present in significant amounts in brown algae. The phloroglucinol based polymers can be classified into different categories based on their bonding patterns and display a wide variety of structural complexities.
