Материалы и методы. В качестве объектов исследования использовались извлечения листьев Elaeagnus argentea, полученные в соотношении 1 : 5 путем настаивания на водяной бане при температуре 60 °С в течение 2 ч при периодическом перемешивании. В качестве экстрагентов использовали воду очищенную и спирт этиловый в концентрациях 40, 50, 60, 80 и 96 %. Полноту выхода биологически активных веществ оценивали по показателю «сухой остаток» и количество флавоноидов и сапонинов в перерасчете на лютеолин-7-глюкозид (CAS № 5373-11-5, чистота основного вещества более 98 %) и олеаноловую кислоту (CAS № 508-02-1, чистота основного вещества более 99 %) соответственно. Результаты. Установлено, что наибольший показатель сухого остатка, количество флавоноидов и сапонинов определены в извлечении, где в качестве экстрагента использовали спирт этиловый 60 % концентрации. Заключение. При получении извлечения на основе листьев Elaeagnus argentea установлено, что оптимальным экстрагентом является спирт этиловый 60 %, при применении которого отмечается наибольшая величина показателя «сухой остаток» и количество флавоноидов и сапонинов.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to study the effect of the extractant on the completeness of the yield of biologically active substances in the development of an extraction form based on the leaves of Elaeagnus argentea. Materials and methods. The objects of the study were extracts of Elaeagnus argentea leaves obtained in a ratio of 1:5 by infusing in a water bath at a temperature of 60 °C for 2 hours with periodic stirring. Purified water and ethyl alcohol in concentrations of 40, 50, 60, 80 and 96 % were used as extractants. The completeness of the BAS yield was estimated by the “dry residue” indicator and the amount of flavonoids and saponins in terms of luteolin-7-glucoside (CAS No. 5373-11-5, purity of the base substance more than 98 %) and oleanolic acid (CAS No. 508-02-1, purity of the base substance more than 99 %), respectively. Results. As a result of the study, it was found that the highest dry residue index, the amount of scrip of flavonoids and saponins were determined in the extraction, where ethyl alcohol of 60% concentration was used as an extractant. Conclusion. Thus, when extracting based on the leaves of Elaeagnus argentea, it was found that the optimal extractant is ethyl alcohol 60 %, when used, the highest value of the "dry residue" indicator and the amount of flavonoids and saponins are noted.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>извлечение</kwd><kwd>экстрагент</kwd><kwd>биологически активные вещества</kwd><kwd>сухой остаток</kwd><kwd>Elaeagnus argentea</kwd></kwd-group><kwd-group xml:lang="en"><kwd>extraction</kwd><kwd>extractant</kwd><kwd>biologically active substances</kwd><kwd>dry residue</kwd><kwd>Elaeagnus argentea</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">Кароматов И.
