The distribution and profile of nutrients and catechins of some Indonesian seaweeds

Total phenolic compounds, radical scavenging and metal chelation of extracts from Icelandic seaweeds

“…A series of polyphenolic compounds such as catechins (e.g. gallocatechin, epicatechin and catechin gallate), flavonols and flavonol glycosides have been identified from methanol extracts of red and brown algae (Santoso, Yoshie, & Suzuki, 2002;Yoshie, Wang, Petillo, & Suzuki, 2000;Yoshie-Stark, Hsieh, & Suzuki, 2003). Phlorotannins, a group of phenolic compounds which are restricted to polymers of phloroglucinol, have been identified from several brown algal families such as Alariaceae, Fucaceae and Sargassaceae.…”

Functional and Nutraceutical Ingredients from Marine Macroalgae

“…A series of phenolic compounds such as catechins (e.g. gallocatechin, epicatechin, and catechin gallate), flavonols, and flavonol glycosides have been identified from methanol extracts of red and brown algae [2][3][4]. Phlorotannins, the largest group of polyphenols in marine brown algae, exhibit many interesting physiological activities ( Based on the type of structural linkages between the phloroglucinol sub-units (diphenylethers or biphenyls) and on the number of additional hydroxyl groups, phlorotannins can be systematically classified into six major subclasses: phlorethols, fucols, fuhalols, fucophlorethols, isofuhalols, and eckols [5,6].…”

Antioxidant Activity of Seaweed Extracts: In Vitro Assays, Evaluation in 5 % Fish Oil‐in‐Water Emulsions and Characterization

“…Marine macroalgae are reported to be rich sources of various natural antioxidants such as catechins (e.g. gallocatechin, epicatechin and catechingallate), flavonols and flavonol glycosides, which have been identified from methanol extracts of red and brown algae [11][12][13]. A group of phenolic compounds found in brown algae called phlorotannins, which are polymers of phloroglucinol, have been reported to possess strong antioxidant activity and their free radical potential is more potent than that of other polyphenols derived from terrestrial plants [14].…”
