Overview of polyphenols and pigments from ten different organizams from the Adriatic sea

Marine environment has been known as a rich source of bioactive compounds, such as proteins, amino acids, polysaccharides, fatty acids, vitamins, minerals, dietary fibers, sterols, pigments and polyphenols (Mišurcová et al., 2014), that have a huge functional and nutraceutical potential. Among these compounds, polysaccharides are recognized as one of the most promising sources of anti inflammatory, antioxidant, antimicrobial, antiviral, anti-coagulant, and antitumor activities. Polysaccharides extraction is preceded by pretreatment with acetone and ethanol in order to remove compounds like polyphenols and pigments that are considered undesirable in polysaccharides extraction so those extracts are usually discarded. However, polyphenols and pigments are valuable biological resources of high exploitation potential. They are produced when these organisms are adapting to extreme environmental conditions (high salt concentration, low light, lower temperatures) they live in (Freile-Pelegrín and Robledo, 2013). This study aimed to characterize and quantify polyphenols and pigments (spectrophotometric and HPLC analysis) in acetone and ethanol extracts from 10 different marine species from the Croatian coast of the Adriatic Sea: 2 green algae (Ulva lactuca and Codium bursa), 5 brown algae (Fucus virsoides, Padina pavonica, Cystoseira barbata, Halopteris scoparia, and Cystoseira compressa), 1 coral (Eunicella cavolini), 1 sea squirt (Aplidium conicum) and 1 sponge (Chondrosia reniformis).
