Антоцианы относятся к фенольным соединениям, которые обладают высокой химической активностью и способны вступать в реакции с АФК, в том числе Н<sub>2</sub>О<sub>2</sub>. На примере листьев растений <italic>La</italic><italic>с</italic><italic>tuca</italic><italic> </italic><italic>sativa</italic> L. и <italic>Ajuga</italic><italic> </italic><italic>reptans</italic> L. с высоким содержанием антоцианов установлено, что для удаления фенольных соединений из экстрактов листьев необходима их предварительная обработка поливинилполипирролидоном (ПВПП) в количестве не менее 7.5% от объема экстракта. Оценен оптимальный временной диапазон экспозиции растительных экстрактов с ПВПП. Удаление фенольных соединений из анализируемых растворов позволяет минимизировать влияние антоцианов на разложение Н<sub>2</sub>О<sub>2</sub>, что повышает репрезентативность данных о содержании Н<sub>2</sub>О<sub>2</sub> в растительных образцах.</p></abstract><trans-abstract xml:lang="en"><p/></trans-abstract><kwd-group xml:lang="ru"><kwd>антоцианы</kwd><kwd>количественный анализ пероксид водорода</kwd><kwd>поливинилполипирролидон</kwd><kwd>хемилюминесценция</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>075-00360-25-00</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Asada K.
