Сосновую пыльцу собирали в июне 2021 года в местах естественного произрастания на юго-восточном побережье озера Байкал. Массовую долю сырого протеина определяли по методу Къельдаля; состав белка и содержание отдельных аминокислот – методом высокоэффективной жидкостной хроматографии с постколоночной модификацией нингидрином на автоматическом анализаторе LA8080 (Hitachi, Япония). Содержание сырого протеина в пыльце составило 14,38–15,94%. Установлено, что в состав белка сосновой пыльцы входят 17 аминокислот, в том числе 9 незаменимых: валин, изолейцин, лейцин, треонин, метионин, фенилаланин, лизин, а также гистидин и аргинин. Содержание суммы аминокислот составило 141,4–156,5 мг/г, в том числе незаменимых аминокислот 45,9–48,4%. Доминирующими в пыльце Pinus sylvestris и Pinus sibirica являются (мг/г): моноаминодикарбоновые кислоты – глутаминовая (21,3–24,2) и аспарагиновая (13,0–14,2), диаминокарбоновая кислота аргинин (17,0–17,4) и гетероциклическая аминокислота пролин (14,7–16,2). Полученные результаты могут быть полезны при разработке лекарственных средств и биологически активных добавок на основе пыльцы Pinus sylvestris и Pinus sibirica, обладающих ввиду наличия вышеуказанных аминокислот ноотропным, иммуномодулирующим, кардиостимулирующим, детоксикационным действием.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study was to determine the qualitative and quantitative amino acid composition of pollen Pinus sylvestris L. and Pinus sibirica Du Tour. Pine pollen was collected in June 2021 at natural sites on the southeastern coast of Lake Baikal. The mass fraction of crude protein was determined by the Kjeldahl method; the protein composition and individual amino acid content were determined by high-performance liquid chromatography with post-column modification of ninhydrin on an LA8080 automatic analyser (Hitachi, Japan). The crude protein content of the pollen was 14.38–15.94%. Pine pollen protein is shown to contain 17 amino acids, including 9 essential amino acids: valine, isoleucine, leucine, threonine, methionine, phenylalanine, lysine, histidine, and arginine. The content of the sum of amino acids was 141.4–156.5 mg/g, including essential amino acids 45.9-48.4%. The following amino acids are dominant in Pinus sylvestris and Pinus sibirica pollens (mg/g): monoaminodicarboxylic acids – glutamic (21.3–24.2) and aspartic (13.0–14.2), diaminocarboxylic acid arginine (17.0–17.4) and heterocyclic amino acid proline (14.7–16.2). The obtained results can be useful in the development of drugs and biologically active additives based on pollen Pinus sylvestris and Pinus sibirica, which, due to the presence of the above amino acids, have a nootropic, immunomodulatory, cardiac stimulating, and detoxifying effect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сосновая пыльца</kwd><kwd>аминокислоты</kwd><kwd>Pinus sylvestris</kwd><kwd>Pinus sibirica</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pine pollen</kwd><kwd>amino acids</kwd><kwd>Pinus sylvestris</kwd><kwd>Pinus sibirica</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках госзадания Байкальского института природопользования СО РАН (АААА-А21-121011890027-0) и при частичной финансовой поддержке гранта Бурятского государственного университета на проведение инициативных исследований № 23-10-0502.</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the state task of the Baikal Institute of Nature Management of the Siberian Branch of the Russian Academy of Sciences (АААА-А21-121011890027-0) and partly supported by grant of Banzarov Buryat State University no. 23-10-0502.</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">Stanley R.G., Linskens H.F.
