Influence of supercritical fluid extraction on lignocellulosic plant matrix and extractive substance yield
Natural substances of plant origin are widely used in pharmacies. However, the quantitative content of biologically active substances in plant cells is insignificant and the currently available extraction methods do not allow for the complete extraction of biologically active substances as a result...

Natural substances of plant origin are widely used in pharmacies. However, the quantitative content of biologically active substances in plant cells is insignificant and the currently available extraction methods do not allow for the complete extraction of biologically active substances as a result of the strong lignocellulose matrix of the cell. Therefore, it is necessary to look for new extraction methods that increase the yield of extractive substances from plant raw materials. This paper is devoted to the effect of supercritical fluid extraction on the quantitative content of extractives contained in a plant cell. The study aims to establish the effect of supercritical fluid extraction on the lignocellulose matrix and the yield of extractive substances. The plant biomass of the vegetative part of the narrow-leaved cypress ( Chamaenerion angustifolium L., Scop., 1771); roots and rhizomes of the stinky bug ( Actaea cimicifuga Schipcz., J Compton); roots and rhizomes of the golden root ( Rhodiola rosea L., 1753) were used as research objects.
