Bioactive Compounds from Three Green Algae Species along Romanian Black Sea Coast with Therapeutically Properties

Abstract

During the past years, it became obvious that the ecosystem presents a marine algae excedent, which should be utilized in one way or another. In the marine world, algae have been intensely studied, but the Black Sea seaweeds are not sufficiently harnessed. To survive in such various diverse and extreme environments, macroalgae produce a variety of natural bioactive compounds and metabolites, such as polysaccharides, polyunsaturated fatty acids, and phlorotannins. In the Black Sea there are three species of green algae: Ulvae lactuca sp., Enteromorpha intestinalis and Cladophora sp. The superior exploitation of the marine biomass represents a highly important resource for the pharmaceutical industry, supplying raw material for the extraction of bioactive substances (vitamins, polysaccharides, sterols, phenols and amino-acids) and various other substances. The purity of this compounds is strongly connected to the state of the marine ecosystem. In the present paper are presented the main bioactive compounds existing in the chemical composition of the green algae in the Black Sea studied. The details of the therapeutic properties of the green algae generated by their chemical compositions.
