Antioxidant Potential of Selected Oil Plants of Brassicaceae Burnett

Abstract

The economically important species of genus Brassica L. were investigated in this study. Alcohol and water plant extracts of cultivars and varieties of Brassica campestris and B. rapa were inspected on antiradical activity by DPPH-method (with 2,2-diphenyl-2-picrylhydrazyl). Obtained extracts were measured on a spectrophotometer at wavelength 515 nm. Antiradical activity of methanol extracts was in the range from 34.29 (B. rapa subsp. rapifera Metzger (f. biennis), f. EOTRFO) to 58.09% (B. campestris f. biennis D.C., cv. Oriana). Water extracts demonstrated this activity in range from 58.18 (B. campestris f. biennis D.C., cv. Oriana) to 84.25% (B. campestris f. biennis D.C. × B. rapa L., f. EOTFVS). Antioxidant activity (AA) of extracts of investigated plants was expressed in ascorbic acid equivalent (mg g -1 AAE). The highest AA of methanol extracts was found for B. campestris f. biennis D.C. × B. rapa L., cv. Fitopal (86.07 mg g -1 AAE), the lowest one -for B. rapa subsp. rapifera Metzger (f. biennis), f. EOTRFO (52.78 mg g -1 AAE). Maximal AA of water extracts was registered for B. campestris f. biennis D.C. × B. napus f. biennis D.C., cv. Innovacia (121.77 mg g -1 AAE), minimal -for B. campestris f. biennis D.C. × B. rapa L., f. EOTFVS (85.18 mg g -1 AAE).

Separation and Determination of Chemopreventive Phytochemicals of Flavonoids from Brassicaceae Plants

“…What is notable is the presence of organosulfur sulforaphane, a representative of isothiocyanates, resulting from the decomposition of glucosinolates [ 12 ]. Brassicaceae demonstrates highly antioxidative properties [ 13 , 14 , 15 , 16 ]. The specific contents of antioxidants differ depending on the plant species, its maturity, harvest time, cultivation conditions, soil quality, storage and transport conditions, and the thermal processing used during the preparation of cabbage dishes [ 17 , 18 , 19 , 20 ].…”

The Structural Diversity of Trichomes and Pubescence of Brassicaceae Burnett of the Flora of Ukraine with an Emphasis on Ecology

“…У світовій економіці хрестоцвіті займають третє місце після злакових та бобових. Серед них багато важливих харчових, кормових, олійних, медоносних, вітамінних, лікарських, а також декоративних рослин (Sokolov, 1985;Ilyinska et al, 2007;Warwick, 2011;Anjum et al, 2018;Rakhmetov et al, 2018;Vergun et al, 2019Vergun et al, , 2020Vergun et al, , 2021Jabeen, 2020). В агропромисловому комплексі та приватному секторі України найчастіше використовують види майже 20 родів, зокрема Armoracia G.Gaertn., B.Mey.…”
