'Розовое облако' в фазу массового цветения, полученного методом гидродистилляции. Идентифицировано 50 компонентов, среди которых основными были: розфуран (47,49±1,93%), розфуранэпоксид (19,00±3,30%) и β-кариофиллен (11,04±1,79%). На основании проведенного анализа существующих литературных данных по компонентному составу эфирного масла E. stauntonii из различных мест произрастания выявлено наличие 7 хемотипов: метилгексагидроазуленово-тимольный; цинеольно-розфурановый; цинеольно-розфуранэпоксид-кариофилленовый; кариофиллен-цинеольный; куминол-кариофилленовый; цинерон-розфуран эпоксидный и розфуран-розфуранэпоксидный. Установлено, что по своему химическому составу эфирное масло E. stauntonii 'Розовое облако', полученное в условиях Южного берега Крыма сходно с образцом из США. Наличие основных компонентов розфурана и розфуранэпоксида свидетельствует о возможности использования данной культуры в парфюмерно-косметической и пищевой промышленности.</p></abstract><trans-abstract xml:lang="en"><p>The article provides data on the mass fraction and component composition of essential oil from the aboveground mass of Elsholtzia stauntonii Benth. 'Rozovoe oblako' in the phase of mass flowering obtained by hydrodistillation. 50 components were identified, among which the main ones were: rosfuran (47,49±1,93%), rosfuran epoxide (19,00±3,30%) and β-caryophyllene (11,04±1,79%). Based on the analysis of existing literature data on the component composition of E. stauntonii essential oil from various growing areas, the presence of 7 chemotypes was revealed: methylhexahydroazulene-thymol; cineol-rosfuran; cineol-rosfuranepoxide-caryophyllene; caryophyllene-cineol; cuminol-caryophyllene; cineron-rosfuran epoxy and rosfuran-rosfuran epoxide. It has been established that the essential oil of E. stauntonii 'Rozovoe oblako', cultivated in the conditions of the Southern Coast of the Crimea, is similar in its chemical composition to the sample from the USA. The presence of the main components of rosfuran and rosfuran epoxide indicates the possibility of using this culture in the perfumery, cosmetics and food industries.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Elsholtzia stauntonii Benth</kwd><kwd>эфирное масло</kwd><kwd>массовая доля</kwd><kwd>компонентный состав</kwd><kwd>хемотипическое разнообразие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Elsholtzia stauntonii Benth</kwd><kwd>essential oil</kwd><kwd>mass fraction</kwd><kwd>component composition</kwd><kwd>chemotypic diversity</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">Дмитриев Л.Б., Бакова Н.Н., Клюев Н.А., Машанов В.И.
