The optical properties and radiation stability of the alcoholic (ethanol) and acetone extracts from brown algae Laminaria Japonica Jemo (D) and Jenit (M) were studied using the method of UV- VIS spectrophotometry. The spectra of optical absorption of the original extracts and their changes at different dilution solvents was registered. It is shown that the nature of algae, the method of cultivation, nature of the solvent effect on the efficiency of extraction of valuable biologically active compounds, including the most important ones are carotenoids and chlorophylls. In this work the special attention was devoted to the study of radiation-chemical transformations of alcohol (ethanol), acetone, water-ethanol (50%) and water-acetone (50%) solutions of extracts of algae under various conditions of simulation of redox reactions due to saturation of the irradiated solutions of different gases: oxygen, argon, or nitrous oxide. The radiation-chemical stability of chlorophyll fractions in different species of algae depending on the conditions of radiolysis was determined. It is known that the chlorophylls are often used in pharmacology as a food colorant, and in the present time as components of photosensitive layers in the nanophotonics. The obtained results on radiation sensitivity of biological compounds from algae can be used to assess their stability under radiation sterilization of raw materials and medicines.
