L’algue Klamath et ses propriétés nutritionnelles. Un extrait spécifique aux effets neuromodulateurs et neuroprotecteurs

Klamath algae and its nutritional properties. A specific extract with the neuromodulating and neuroprotective effects

Résumé

La Klamath (Aphanizomenon flos-aquae [AFA] Ralfs ex Born. & Flah. Var. flos aquae), microalgue unicellulaire d’eau douce du lac Klamath (états-Unis), a un profil nutritionnel très complet et à haute biodisponibilité: 20 acides aminés, plus de 60 minéraux et oligoéléments identifiés, 14 vitamines, 15 caroténoïdes, de la chlorophylle, des β-carotènes, AG omégas 3 et 6, polyphénols, ainsi que des molécules spécifiques algales telles que mycosporine-like aminoacids (MAAs) [mycosporines algales], AFA-phycocyanines (AFA-PCs), β-phényléthylamine (PEA). Les recherches menées par le Centre de recherches nutrithérapiques (Urbino, Italie) en collaboration avec l’université d’Urbino ont permis la mise au point d’un extrait spécifique breveté, ayant une importante action neuromodulatrice et neuroprotectrice. L’intérêt de cet extrait, obtenu par une méthode d’extraction mécanique sans solvant chimique (ultrafiltration), repose sur la synergie d’action de la PEA (β-PEA) avec d’autres molécules microalgales, notamment les AFA-phycocianines, les AFA-phytochrome et les MAAs, qui favorisent son action au niveau cérébral en agissant comme inhibiteurs sélectifs de la MAO-B. Cet extrait spécifique contient, donc, un complexe synergique de molécules qui apporte un effet bénéfique sur le mental, contribuant à combattre le vieillissement des fonctions neuronales.

Abstract

Klamath algae (Aphanizomenon flos-aquae [AFA] Ralfs ex Born. & Flah. Var. flos aquae), an unicellular microalgae living in the Klamath freshwater lake (USA), presents a very complete nutritional profile, with a very high bioavailabitlity level: 20 amino-acids, more than 60 minerals and trace elements, 14 vitamins, 15 carotenoids, chlorophyll, β-carotenes, omega-3 and omega-6 fatty acids, and algae specific molecules such as mycosporine-like aminoacids (MAAs) [algae mycosporins], AFA-phycocyanins (AFA-PCs), β-phenylethylamin (PEA). Research works performed by the Nutritherapeutic Research Centre (Urbino, Italy) in collaboration with the University of Urbino, allowed to develop a patented specific extract, with an important neuromodulating and neuroprotective action. The advantages of this extract, obtained via a mechanical extraction process without any chemical solvent (ultra-filtration), come from the synergistic action of PEA (β-PEA) with other microalgae molecules, especially AFA-phycocianins, AFA phytochromes and MAAs, who exert selective inhibiting effects on MAO-B and thus facilitate the action of PEA on the cerebral function. That specific extract contains a synergistic complex of molecules providing beneficial effects on the mental condition, contributing to prevent the ageing of neuronal functions.
