The method was used for the extraction of bioactive phenolic compounds from two freshwater microalgae (Anabaena doliolum, Spongiochloris spongiosa) and from food products of marine macroalgae Porphyra tenera (nori) and Undaria pinnatifida (wakame). The analyses showed that the freshwater algae and marine algal products contained sub-microgram or microgram level of phenolics per gram of lyophilized sample. In addition, the total phenol content (Folin–Ciocalteu assay) and antioxidant activity (TEAC assay, Trolox equivalent antioxidant capacity assay) of the PLE–SPE extracts were determined and discussed Pracoviště Mikrobiologický ústav Kontakt Eliška Spurná, eliska.spurna@biomed.cas.cz, Tel.: 241 062 231 Rok sběru 2010
