The basic materials were: a ground plant raw material of Helichrysi arenarii flowers. water solutions of ethanol (26, 43, 59, 72, 81, 97±1% v/v.), methanol, 1-propanol, 2-propanol, acetone and ethyl acetate. The extracts were obtained from the plant raw materials / solvent at the ratio of 1:5 (wt./vol.) by maceration for 24 hours at the temperature of 24±1°С.

A dependence of isosalipurposide concentration in ethanol-water extracts on ethanol concentration in the solution was studied. It has been found out that maximum concentration of isosalipurposide is observed in the solutions with ethanol concentration of 75±5% v/v. This range of ethanol concentrations corresponds to solvent’s dielectric constant value of 38±3 units. The regression equation of dependence between isosalipurposide concentration in the extract and dielectric constant of ethanol-water solution has been obtained. Optimal concentration of the solvent has been theoretically predicted and experimentally verified as in the case of   water solutions of methanol, acetone, 1-propanol, and 2-propanol.</p></sec><sec><title>Conclusion</title><p>Conclusion. It has been determined that solvent’s dielectric constant has the most significant influence on the extraction process of phytocompound from the plant raw material. A mathematical model for description of the dependence of isosalipurposide concentration on dielectric constant of ethanol-water solutions has been substantiated theoretically and tested. The optimal range of solvent’s dielectric constant to obtain maximum concentration of isosalipurposide in the extract has been found.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Бессмертника песчаного цветки</kwd><kwd>растворители</kwd><kwd>ВЭЖХ анализ</kwd><kwd>диэлектрическая константа</kwd><kwd>изосалипурпозид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helichrysi arenarii flowers</kwd><kwd>solvents</kwd><kwd>HPLC analysis</kwd><kwd>dielectric constant</kwd><kwd>isosalipurposide</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Fayaz M., Bhat M.H., Kumar A., Jain A.K.
