Differences in Leaf Color and Stage of Development at Harvest Influenced Phytochemical Content in Three Cultivars of Kale (Brassica oleracea L. and B. napus)

Abstract: Microgreens and red colored plants have been suggested to contain higher level of health promoting phytochemicals. Kale (Brassica oleracea L. and other species) is regarded as a ‘superfood’ due to its antioxidant properties. In our study, three kale cultivars (B. oleracea L. ‘Dwarf Blue Curled’ and ‘Scarlet’, and B. napus ‘Red Russian’) differing in leaf pigmentation were harvested at five different leaf developmental stages and th… Show more

“…Supernatants were combined and stored at −80 • C until analysis. TPC was determined with modifications for a 96-well microplate according to Waterland et al (2019). In brief, 18.2 µL of sample extract or gallic acid standard was plated in duplicates, followed by 90.9 µL of 0.5 N Folin-Ciocalteau reagent (Sigma-Aldrich, St. Louis, MO).…”

“…Существенной разницы в содержании фенольных соединений у зеленых сортов не было, однако, из красных сортов самым высоким количеством растворимых фенольных соединений характеризовался сорт «Scarlet». В исследовании (Waterland et al, 2019), которые изучали содержание полифенолов в трех разных сортах капусты кейл 'Dwarf Blue Curled' 'Scarlet' и 'Red Russian', было показано, что содержание полифенолов составляло от 145до 284 мг/100 г сырого веса [11]. В работе (Sikora, Bodziarczyk., 2012) общее содержание фенолов в листьях (B. oleracea L. convar.…”

“…Согласно их данным количество флавноидов в капусте кейл было 97,4-298,5 мг/100г сырого веса [10]. Одной из причин высокого уровня флавоноидов у сортов красной капусты может быть то, что они содержат очень большое количество антоцианов, по сравнению с зелеными сортами [11].…”
