Determination of biologically active substances in Black Sea algae//Определяне на биологично активни вещества в черноморски водорасли

[EN] Marine organisms, especially marine algae are one of the most complete and natural food sources rich in a number of vital biologically active compounds, including polyunsaturated fatty acids, sterols, proteins, polysaccharides, antioxidants, pigments among others. Various biologically active substances in algae and valuable applications of algae in practice are described in the literature review. Among the biologically active substances lipids, in particular basic and essential fatty acids, phospholipids, sterols, fat-soluble vitamins and macro- and trace elements contents in macroalgae are discussed. The aim of the thesis is to study different species of Black Sea macroalgae as sources of various biologically active substances and nutrients in relation to their use for the production of food, pharmaceutical and cosmetic products. Taxonomy of the seaweeds is described. Results were obtained for the fatty acid profile of total lipids, individual phospholipids and sterol esters. This thesis incestigates the content of fat-soluble vitamins and carotenoids (?-tocopherol, ?-carotene and astaxanthin) in the Black Sea algae selected. The final step is to perform an evaluation of the potential of the Black Sea algae as raw materials for food, pharmaceutical and cosmetic industries, showing that they are a very good source of the biologically active substances and essential nutrients investigated.
