Caulerpa cupressoides var. lycopodium (Chlorophyta) contains three SPs fractions (Cc-SP1, Cc- SP2 and Cc-SP3). Cc-SP1 and Cc-SP2 had anticoagulant (in vitro) and anti- and prothrombotic, antinociceptive and/or anti-inflammatory (in vivo) effects. However, their structural features have not yet been investigated. This study analyzed the chemical composition, elemental microanalysis and structural features by infrared (IR) and nuclear magnetic resonance (1H NMR) spectroscopy of Cc-SPs. Fractionation of SPs by DEAE-cellulose yielded Cc-SP1, Cc-SP2 and CcSP3 containing differences among the relative proportions of sulfate (14.67-26.72%), total sugars (34.92-49.73%) and uronic acid (7.15-7.22%). Carbon (21.76-29.62%), sulfate (2.16-4.55%), nitrogen (0.85-1.57%) and hydrogen (4.57-5.86%) contents were obtained using a CHN equipment. Data from IR indicated occurrence of sulfate ester, galactose-6-sulfate, uronic acid and glycoside linkages. For 1H NMR spectrum of the soluble Cc-SP1 fraction, it was mainly found β-galactopyranose residues and CH3 group. The results showed that Cc-SPs fractions have some structural features similar to others studied Caulerpaceae SPs. 2014 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303230170002 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
