В настоящее время остро стоит проблема повышения эффективности использования лесных ресурсов. Одним из таких ресурсов являются шишки сосны обыкновенной, которые остаются на местах рубки леса. Полисахариды сосны обыкновенной шишек обладают выраженной сорбционной активностью, однако остается не ясным влияет ли на сорбционную активность, в каком месяце проводилась заготовка сырья.</p></sec><sec><title>Цель</title><p>Цель. Исследование содержания, сорбционной активности и молекулярной массы водорастворимых полисахаридов сосны обыкновенной шишек в разные сезоны года.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Водорастворимый полисахаридный комплекс (ВРПК) сосны обыкновенной шишек получали по методике, основанной на известной схеме разделения углеводов по Бэйли с соавторами. ВРПК получали из образцов сосны обыкновенной шишек, заготовленных с июля по март. Определение содержания ВРПК сосны обыкновенной шишек проводили спектрофотометрически, модифицированным антрон-серным методом Дрейвуда. Определение сорбционной активности полисахаридов проводили по метиленовому синему. Молекулярную массу полисахаридов определяли вискозиметрическим методом.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Определено содержание ВРПК в шишках сосны обыкновенной с июля по март. Самый высокий выход ВРПК отмечен в зимний период (3,24 ± 0,31 %), а наименьший – в летний (0,46 ± 0,01 %). Исследована сорбционная активность ВРПК шишек сосны обыкновенной по метиленовому синему с июля по март in vitro. Установлено, что наибольшей сорбционной активностью ВРПК обладает в октябре (230,69 ± 4,18 %) и ноябре (243,30 ± 9,43 %). Сорбционная активность ВРПК превышает активность препаратов сравнения угля активированного (230,9 ± 2,34 мг/г) и диоксида кремния коллоидного («Полисорб МП») (211,5 ± 1,87 мг/г). Определена средняя молекулярная масса ВРПК шишек сосны обыкновенной с июля по март. Средняя молекулярная масса ВРПК находится в пределах от 6 872,27 до 21 598,06. Установлена зависимость сорбционной активности ВРПК сосны обыкновенной шишек от молекулярной массы.</p></sec><sec><title>Заключение</title><p>Заключение. Водорастворимый полисахаридный комплекс сосны обыкновенной шишек, полученный в разное время года, обладает разной сорбционной активностью, которая зависит от молекулярной массы полисахарида. Наибольшее содержание и сорбционная активность ВРПК шишек сосны обыкновенной совпадает с периодом заготовки древесины, что обуславливает практическое применение шишек и перспективу дальнейших исследований.  </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Currently, there is much tension around the issue of increasing the efficiency of use of forest resources. One of these resources are scotch pine cones, which remain at the felling areas. Polysaccharides of scotch pine cones have a significant sorption activity; however, it remains unclear does the month, when raw materials were collected, affect the sorption activity.</p></sec><sec><title>Aim</title><p>Aim. The research of the content, sorption activity and molecular weight of water-soluble polysaccharides of scotch pine cones in different seasons of the year.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Water-soluble polysaccharide complex (WSPC) of scotch pine cones was obtained with a method based on the well-known scheme for the carbohydrates separation according to Bailey et al. WSPC was obtained from the samples of scotch pine cones collected from July till March. Determination of the content of scots pine cones WSPC was spectrophotometrically carried out, with the modified Draywood anthrone-sulfurous method. The sorption activity of polysaccharides was determined by the methylene blue. The molecular weight of polysaccharides was identified by the viscosimetric method.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The content of WSPC in scotch pine cones from July till March was identified. The highest yield of WSPC was registered in winter (3.24 ± 0.31 %), and the lowest in summer (0.46 ± 0.01 %). The sorption activity of scotch pine cones WSPC in terms of methylene blue from July till March was researched in vitro. It was found that WSPC has the highest sorption activity in October (230.69 ± 4.18 %) and November (243.30 ± 9.43 %). The WSPC sorption activity is above the activity of standard medications: absorbent carbon (230.9 ± 2.34 mg/g) and colloidal silicon dioxide ("Рolisorb MP") (211.5 ± 1.87 mg/g). The average molecular weight of scotch pine cones WSPC from July till March was determined. The average molecular weight of WSPC is in the range from 6 872,27 to 21 598,06. The dependence of the scotch pine cones WSPC sorption activity on the molecular weight was registered.</p></sec><sec><title>Conclusion</title><p>Conclusion. The water-soluble polysaccharide complex of scotch pine cones, obtained at different seasons, has different sorption activity, which depends on a polysaccharide molecular weight. The highest content and sorption activity of scotch pine cones WSPC matches with the period of wood production, which stipulates a practical use of cones and directions for future research.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сосна обыкновенная</kwd><kwd>сосновые</kwd><kwd>полисахариды</kwd><kwd>сорбционная активность</kwd><kwd>молекулярная масса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scotch pine</kwd><kwd>pinaceae</kwd><kwd>polysaccharides</kwd><kwd>sorption activity</kwd><kwd>molecular weight</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование проведено при финансовой поддержке Пермского научно-образовательного центра «Рациональное недропользование», 2022 год.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was carried out with the financial support of the Perm Scientific and Educational Center "Rational Subsoil Use", 2022.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lee A.
