Показаны возможности практического использования растительного сырья в лекарственных целях. Отражены места произрастания вида в Казахстане как по гербарным образцам, так и по материалам собственных исследований. В результате обследований выявлены точки произрастания N. candida на территории государственного национального природного парка «Кокшетау» (Северный Казахстан). Ими являются водоемы - водопад «Өмір суы» филиала «Орманды булак» и Урочище «Уварово» Нижне-Бурлукского лесничества Арыкбалыкского филиала. Площадь популяций не превышает 0,2 га для каждого водоема. Показана фитоценотическая роль вида как важного компонента водных экосистем региона и даны предложения по его сохранению.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of scientific data on biological characteristics, stages of development, chemical properties of individual organs (leaves, roots, flowers, etc.), biological activity of compounds isolated from the pure white water lily (Nymphaea candida J.Presl &amp; C.Presl). The possibilities of practical use of plant raw materials for medicinal purposes are shown. The places of growth of the species in Kazakhstan are reflected both according to herbarium samples and according to the materials of their own research. As a result of the surveys, the growth places of N. candida were found on the territory of the State National Natural park "Kokshetau" (Northern Kazakhstan). They are reservoirs - the Omir Suiy waterfall of the Ormandy Bulak branch and the Uvarovo urochishche of the Nizhne-Burluk forestry district of the Arykbalyk branch. The population area does not exceed 0.2 ha for each reservoir. The phytocenotic role of the species as an important component of the aquatic ecosystems of the region is shown and suggestions for its conservation are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Nymphaea candida</kwd><kwd>биологические особенности вида</kwd><kwd>химический состав</kwd><kwd>распространение</kwd><kwd>применение</kwd><kwd>биологические активные вещества</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Nymphaea candida</kwd><kwd>biological features of the species</kwd><kwd>chemical composition</kwd><kwd>distribution</kwd><kwd>practical use</kwd><kwd>biological active compounds</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">Nowak A., Nobis M., Dajdok Z., Zalewska-Gałosz J., Nowak S., Nobis A., Czerniawska-Kusza I., Kozak M., Stebel A., Bula R., Sugier P., Szlachetka A., Bena W., Trojecka A., Piwowarczyk R., Adamiec A., Krawczyk R.
