The purpose of this work is to investigate the influence of supercritical fluid extraction parameters and the quality of the feedstock on the yields of pigments from the Led Flyweed. As a method of extracting the target components, supercritical fluid extraction was used. To quantify the target components, spectrophotometric and chromatographic methods were used, antioxidant activity was determined on the anti-oxidant activity analyzer «Blizar». Comparison of the conditions for the isolation of chlorophylls and carotenoids of Ledum palustre (Ledum palustre) when using supercritical carbon dioxide and ethyl alcohol as extractants is compared. The parameters of supercritical fluid extraction for obtaining extracts enriched with one or both pigments are determined. It is established that the variation of the pressure and temperature of the fluid, the duration of processing and the moisture content of the raw material allows one to extract extracts enriched with one or both extractable pigments. The optimum amount of ethanol used as cosolvent is 5 volume% and is necessary and sufficient for efficient extraction of pigments by supercritical CO2. The data obtained are significant for the pharmaceutical, food and perfume and cosmetic industries, where natural dyes and antioxidants are required. The problem of developing their production and isolation is solved. Technologies are being developed for obtaining pigments from plants, which were previously widely used for the manufacture of medicines.
