Alzheimer's disease affects nearly 36.5 million people worldwide, and acetylcholinesterase inhibition is currently considered the Main therapeutic strategy against it. Seaweed biodiversity in Brazil represents one of the most important sources of-biologically active Compounds for applications in phytotherapy. Accordingly, this study aimed to carry out a quantitative and qualitative assessment, of Hypnea musciformis (Wulfen) J.V. Lamouroux, Ochtodes secundiramea (Montagne) M.A. Howe, and Pterocladiella capillacea (S.G. Gmelin) Santelices & Hommersand (Rhodophyta) in order to determine the AChE effects from their extracts. As a matter of fact, the O. secundiramea extract showed 48% acetylcholinesterase inhibition at 400 mu g/ml. The chemical composition of the bioactive fraction was determined by gas chromatography-mass spectrometry (GC-MS); this fraction is solely composed of halogenated monoterpenes, therefore allowing assignment of acetylcholinesterase inhibition activity to them. 2015 (C) Sociedade Brasileira de Farmacognosia.
