It is well known that biomass of plant origin contains a wide range of substances highly promising for the use in practice. In particular, waxes, lipids, carotenoids, flavonoids, antioxidants, vitamins, biologically active substances, pigments, etc. For the isolation of valuable substances from specific parts of plants, it is necessary to find suitable extraction conditions, a plant material pre-treatment and a selection of a suitable solvent system with sufficient selectivity to extract the desired ingredients from raw biomaterial. Regarding the subsequent application of the substances obtained in areas beneficial to human health, it is also necessary to choose a solvent not only harmless to health but also having no negative impact on the environment. Furthermore, it is desirable to determine the optimum operating ratio of the plant drug to the extraction agent, operating temperature, and to design the particular technological process, i.e.\nto determine the conditions of the solid phase interaction and the extraction agent.\n
