Marine organisms have been increasingly regarded as good sources of new drugs for human therapeutics and also as nutrients for human diet. The amino acids, fatty acids and sterols profiles of the widely consumed echinoderms Paracentrotus lividus Lamarck (sea urchin), Holothuria forskali Chiaje (sea cucumber), the gastropod molluscs Aplysia fasciata Poiret and Aplysia punctata Cuvier (sea hares), from...
In this work a fast and simple multi-target gas chromatography–mass spectrometry (GC–MS) method for the simultaneous detection and absolute quantification of amino acids, fatty acids, sterols and lupanes in marine organisms is proposed. The methodology was applied to the characterization of the echinoderm Marthasterias glacialis Linnaeus spiny sea star extracts. The main factors influencing the extraction...
Catharanthus roseus is nowadays one of the most studied medicinal plants. In this work, further knowledge on different parts of this species (leaves, stems, seeds and petals) was achieved, namely phenolics by HPLC-DAD and organic acids and amino acids by HPLC-UV. Also, the biological potential, expressed as acetylcholinesterase inhibitory activity was accessed and, in some parts, an acetylcholinesterase...
