“…As is evident from Figure 2, total polyphenols and total phenolic acid content did not differ between analyzed samples, while we noticed differences in flavonoid compounds. This observation is different than in our previous study on four-week-old white cabbages grown from different seed producers, where we noticed significant differences in total polyphenols, flavonoids, and flavanols, and moderate differences in total phenolic acid content [10]. A previous study on Polish B. oleracea var.…”

“…For determination of polyphenolic compounds, we performed extraction using 60 mg of dry samples and 2 mL of 80% methanol as we reported earlier [10]. The level of polyphenolic compounds was determinate in 2 mL reaction volumes [10]. Total phenolic content was determinate using Folin-Ciocalteu reagent [12] and results are expressed as equivalents of gallic acid per dry weight (mg GAE g −1 dw).…”

“…For total flavonoids determination, we used the method with AlCl 3 according to Zhishen et al [13], and results are expressed as catechin equivalents per dry weight (mg CE g −1 dw). The total flavanol (TFL) content was determined using the p-dimethylaminocinnamaldehyde (DMACA) method [14] with modifications [10], and results are expressed as catechin equivalents per dry weight (µg CEg −1 dw). Total proanthocyanidins (TPA) were determined using vanillin-HCl methods [15] with modification [10], and results are expressed as catechin equivalents per dry weight (mg CE g −1 dw).…”

Influence of Seed Origin on Morphological Characteristics and Phytochemicals Levels in Brassica oleracea var. acephala

Brassica oleracea var. acephala production and seed selection in the Mediterranean region is traditionally limited to private, family needs or small enterprises. In recent years it became popular, especially in the US, and known as a superfood due to the presence of specialized metabolites associated with health benefits, mainly from polyphenols, glucosinolates, and carotenoids groups. With the increasing popularity of this plant, there is a growing interest in its commercial production. Therefore, in the present work we aimed to study how seed origin influences the content of specialized metabolites in B. oleracea var. acephala. We grew plants from six different seed producers, in a hydroponic system under controlled conditions, and determined seed germination percentage, morphological characteristics, pigments, polyphenols, glucosinolates, and carotenoids content, as well as antioxidant activity. Seed origin influenced germination percentage, yield, and slightly morphological characteristic, but did not influence pigments, total polyphenols, phenolic acids, glucosinolates, and carotenoids content. However, content of flavonoids, ferulic, sinapinic, and, consequently, antioxidant activity was slightly different.

“…They possess strong antioxidant activity due to their ability to scavenge reactive oxygen species and inhibit oxidative stress (Rice-Evans et al, 1995;Pourcel et al, 2007). Variation in the amounts of these phytochemicals depends upon factors such as cultivar genotype, developmental stage, growing conditions, season, soil properties, and post-harvest storage conditions (Kurilich et al, 1999;Vallejo et al, 2002;Jeffery et al, 2003;Singh et al, 2007;Nath et al, 2011;Samec et al, 2011;Samec et al, 2013).…”

Florets, leaves, and stems of twelve commercial broccoli cultivars grown in the spring and fall seasons at the National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), Suwon, South Korea were evaluated for glucosinolates, vitamin C, total phenol, and total flavonoid contents and antioxidant activity. The levels of all phytochemicals and antioxidant activity were significantly influenced by cultivar (C), plant part (P), and growing season (S). Among the glucosinolates, glucoraphanin and glucobrassicin were the major constituents. The highest total glucosinolate content was found in the florets of plants grown in both seasons. Phenols and flavonoids were highest levels in leaves, while vitamin C was highest in stems, suggesting that broccoli leaves and stems may be good sources of such phytochemicals. The levels of all phytochemicals were generally higher in florets in the spring than in the fall, but were higher in leaves and stems during the fall than the spring. Furthermore, higher cultivar-dependent and tissue-dependent variation was observed in the spring than in the fall. Total phenol content exhibited a strong positive correlation (r = 0.674**) with antioxidant activity, followed by total flavonoid content (r = 0.497**), indicating their significant contribution to total antioxidant activity.
