(айвы китайской) являются ценным источником биологически активных соединений. Целью данного исследования было оценить антиоксидантную активность, общее содержание полифенолов, флавоноидов и фенольных кислот в плодах Pseudocydonia sinensis (кожура и мякоть) коллекции Национального ботанического сада им. Н. Н. Гришко (г. Киев, Украина). Все исследуемые образцы (кожура и мякоть) проявляли активность по удалению радикалов DPPH со значениями от 9,31 до 10,23 и от 5,39 до 6,85 мг ТЭ/г (тролокс эквивалент), соответственно. Антиоксидантная активность, определяемая методом антиоксидантного восстановления молибдена, варьировала от 122,0 до 219,31 (кожура) и от 62,19 до 95,44 (мякоть) мг ТЭ/г сухого вещества.</p><p>Общее содержание полифенолов в кожуре и мякоти составляло от 53,17 до 78,67 и от 32,31 до 47,41 мг ГКЭ/г (эквивалент галловой кислоты), соответственно. Общее содержание флавоноидов варьировало от 9,15 до 26,18 (кожура) и от 0,55 до 0,87 (мякоть) мг КЭ/г (эквивалент кверцетина). Содержание фенольных кислот в кожуре и мякоти плодов составляло от 4,40 до 8,39 и от 1,12 до 3,97 мг ККЭ/г (эквивалент кофейной кислоты), соответственно. Результаты показали, что экстракты кожуры имели самое высокое содержание биологически активных соединений по сравнению с экстрактами мякоти. Различия между генотипами были значительными по всем наблюдаемым параметрам. Содержание полифенолов имеет высокую положительную корреляцию между антиоксидантной активностью и содержанием фенолов, флавоноидов и фенольной кислоты. Этот вид является потенциальным для размножения и практического использования на Украине.</p></abstract><trans-abstract xml:lang="en"><p>Pseudocydonia sinensis Schneid. (Chinese quince) fruits are an excellent source of bioactive compounds. The objective of this study was to evaluate the antioxidant activity, total polyphenol, ﬂavonoid, and phenolic acid content of dry Pseudocydonia sinensis fruits (peel and pulp) of collection fromM.M.GryshkoNationalBotanical Garden (Kyiv,Ukraine). All tested samples (peel and pulp) exhibited DPPH radical scavenging activities with values from 9.31 to 10.23 and from 5.39 to 6.85 mg TEAC/g (trolox equivalent), respectively. Antioxidant activity determined by the molybdenum reducing antioxidant power method was ranged from 122.0 to 219.31 (peel) and from 62.19 to 95.44 (pulp) mg TEAC/g of dry matter (DM). The total polyphenol content of peel and pulp was ranged from 53.17 to 78.67 and from 32.31 to 47.41 mg GAE/g (gallic acid equivalent), respectively. The total ﬂavonoid content was ranged from 9.15 to 26.18 (peel) and from 0.55 to 0.87 mg QE/g (pulp) (equivalent to quercetin). The phenolic acids content of peel and pulp fruits was ranged from 4.40 to 8.39 and from 1.12 to 3.97 mg CAE/g (caffeic acid equivalent), respectively. The results showed that peel extracts had the highest content of bioactive compounds compared with pulp extracts. Differences between the genotypes were signiﬁcant in all observed parameters. The polyphenol content presents high positive correlations between antioxidant activity and phenolic content, ﬂavonoid, and phenolic acid. This species is potential for propagation and practice use inUkraine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Pseudocydonia sinensis</kwd><kwd>плоды</kwd><kwd>антиоксиданты</kwd><kwd>полифенолы</kwd><kwd>флавоноиды</kwd><kwd>фенольные кислоты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pseudocydonia sinensis</kwd><kwd>fruits</kwd><kwd>antioxidants</kwd><kwd>polyphenols</kwd><kwd>ﬂavonoids</kwd><kwd>phenolic acids</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Materials are published in the framework of the event, held with the ﬁnancial support of the Russian Foundation for Fundamental Research, project No.19-01-20005».
