Антиоксидантную активность определяли спектрофотометрически, с использованием реактива 2,2-дифенил-1- пикрилгидразилоа. Установлено, что накопление водорастворимых веществ-антиоксидантов в листьях сливы в период с июня по август меняется в пределах 63,46-84,79%. Максимальное содержание спирторастворимых веществ - антиоксидантов в листьях отмечено в июле (94,6%). В июне и августе - минимальное (93,28%). Это может быть связано с активным созреванием плодов. Также возможно, что антиокислительные свойства листьев сливы обусловлены синтезом соединений различной полярности. Зависимости между величиной антиоксидантной активности листьев и устойчивостью к клястероспориозу не установлено.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of studies of changes in the antioxidant activity of aqueous and alcohol leaf extracts of 12 accessions of three species of plums (Prunus domestica L., Prunus salicina L., Prunus rossica Erem.) аnd complex hybrids. The antioxidant activity was determined spectrophotometrically using a 2,2-diphenyl-1-picrylhydrazyloa reagent. It is established that the accumulation of water-soluble antioxidant substances in the leaves of the plum varies between 63 and 46-84,79 (%) in the period from June to August. The maximum content of alcohol-soluble substances - antioxidants in the leaves was noted in July (94,6%). In June and August it was noted the minimum (93,28%). This may be due to active ripening of the fruit. It is also possible that the antioxidant properties of plum leaves are due to the synthesis of compounds of different polarity. Dependence between the value of antioxidant activity of the leaves and resistance to the clasterosporium is not established.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лист</kwd><kwd>антиоксидантная активность</kwd><kwd>устойчивость к клястро- спориозу</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Prunus L</kwd><kwd>Prunus L</kwd><kwd>leaf</kwd><kwd>antioxidant activity</kwd><kwd>resistance to clasterosporium</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">Yu M.
