Potential Anti-Aging Substances Derived from Seaweeds

WebbPhlorotannins are found mainly in marine organisms such as brown algae and they are structurally perhaps the most simple tannin group. Individual phlorotannins are composed of two or more phloroglucinol (Fig. 1a) units that are attached to each other via C-C or C-O-C bonds, thus yielding oligomers such as the tetrameric phlorotannin (Fig. 1b ...

Phlorotannins are a type of tannins found in brown algae such as kelps and rockweeds or sargassacean species, and in a lower amount also in some red algae. Contrary to hydrolysable or condensed tannins, these compounds are oligomers of phloroglucinol (polyphloroglucinols). As they are called tannins, … Visa mer Most of the phlorotannins' biosynthesis is still unknown, but it appears they are formed from phloroglucinols via the acetate-malonate pathway. They are found within the cell in small vesicles called … Visa mer In many studies where individual phlorotannins are isolated, extracted phlorotannins are acetylated with acetic anhydride-pyridine to protect them from oxidation. Both … Visa mer The functions of phlorotannins are still an actual research subject (2012). They show primary and secondary roles, at both cellular and organismic scale. Primary roles Structural The structural role of … Visa mer The nomenclature system for the marine phlorotannins was originally introduced by Glombitza. Phlorotannins are … Visa mer It has demonstrated that phlorotannins can have anti-diabetic, anti-cancer, anti-oxidation, antibacterial, radioprotective and anti-HIV … Visa mer • Riitta Koivikko. 2008.
