   <abstract xml:lang="ru">
    <p>Цель исследования – определение качественного и количественного состава стильбенов в молодых весенних проростках растения горца японского (Reynoutria japonica). Исследование про-водилось в Федеральном научном центре биоразнообразия наземной биоты Восточной Азии ДВО РАН (Россия). Объекты исследования – весенние проростки R. japonica, собранные весной в 2025 г. на территории дендрария Горнотаежной станции – филиала ФНЦ Биоразнообразия ДВО РАН (Приморский край, Россия). Отбор материала проводили в фазе активного роста пророст-ков, что позволяло минимизировать влияние онтогенетической неоднородности на химический состав образцов. Всего было собрано по три проростка с каждого из восьми материнских рас-тений; объединенные пробы от каждого растения рассматривались как независимые биологи-ческие повторности. В качестве основного метода исследования использовалась высокоэф-фективная жидкостная хроматография с ультрафиолетовым и масс-спектрометрическим де-тектированием (ВЭЖХ-УФ-МС/МС). Для анализа методом ВЭЖХ-УФ-МС/МС побеги R. japonica высушивали при 60 °C в течение 48 ч и измельчали на лабораторной мельнице IKA A 10 basic. Были оптимизированы условия экстракции стильбенов, включая подбор растворителя (метанол, этанол, вода), температуры (20, 40, 60 °C) и продолжительности процесса (2, 4, 6 ч). Молодые проростки характеризовались исключительно высоким содержанием стильбенов. Основными идентифицированными соединениями стали ресвератролозид, транс-полидатин и транс-ресвератрол. Наибольшая эффективность экстракции была достигнута при использовании 70 % метанола и 70 % этанола (до 78 и 86,6 мг/г сухой массы соответственно) в течении 2 ч, а оптимальными параметрами являлись температура 60 °C и время экстракции 6 ч. При опти-мальных условиях суммарное содержание стильбенов из проростков R. japonica достигало 95 мг/г сухой массы, что сопоставимо с показателями, ранее зарегистрированными для этого и других видов растений. Весенние проростки горца японского (R. japonica) являются одним из са-мых богатых известных природных источников стильбенов.</p>

    <p>The aim of the study is to investigate the qualitative and quantitative composition of stilbenes in young spring seedlings of Japanese knotweed (Reynoutria japonica). Research was conducted at the Federal Scientific Center for Biodiversity of Terrestrial Biota of East Asia, Far Eastern Branch of the Russian Academy of Sciences (Russia). The objects of the study were spring seedlings of R. japonica, collected in the spring of 2025 from the arboretum of the Gornotaezhnaya Station, a branch of the Federal Scientific Center for Biodiversity, Far Eastern Branch of the Russian Academy of Sciences (Primorsky Region, Russia). The material was collected during the active growth phase of the seedlings, which minimized the influence of ontogenetic heterogeneity on the chemical composition of the samples. A total of three seedlings were collected from each of the eight maternal plants; the combined samples from each plant were considered independent biological replicates. High-performance liquid chromatography with ultraviolet and mass spectrometric detection (HPLC-UV-MS/MS) was used as the primary research method. For HPLC-UV-MS/MS analysis, R. japonica shoots were dried at 60 °C for 48 h and ground in an IKA A 10 basic laboratory mill. Stilbenes extraction conditions were optimized, including solvent selection (methanol, ethanol, water), temperature (20, 40, 60 °C), and process duration (2, 4, 6 h). Young seedlings were characterized by exceptionally high stilbenes content. The main identified compounds were resveratrol, trans-polydatin, and trans-resveratrol. The highest extraction efficiency was achieved using 70 % methanol and 70 % ethanol (up to 78 and 86.6 mg/g dry weight, respectively) for 2 h, and the optimal parameters were a temperature of 60 °C and an extraction time of 6 h. Under optimal conditions, the total stilbenes content from R. japonica seedlings reached 95 mg/g dry weight, which is comparable to values previously recorded for this and other plant species. Spring sprouts of Japanese knotweed (R. japonica) are one of the richest known natural sources of stilbenes.</p>
