Abstract
The technology for producing an extract from tubers of stachys using water as an extractant has been developed. Proved and developed has been a process for extracting the plant raw material. A comparative analysis of the content of extractives in the obtained extracts is given. The dependence of the mass fraction of extractives on sonication duration has been studied. The chemical composition of tubers and polysaccharides in tubers and leaves of stachys has been studied. The qualitative and quantitative analysis of biologically active substances contained in the tubers of stachys has been done. The presence of a variety of biologically active substances such as proteins and carbohydrates has been established. It has been shown that the content of extractives is 28,6 % and that of polysaccharides is 6,14 %. When extracting the leaves of stachys the content of extractives is 15,6 % and that of polysaccharides is 2,52 %.Keywords
