A new extraction technique based on the off-line combination of pressurized-liquid with solid-phase extraction (PLE–SPE) is described. 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
