“…Phytochemical screening results of broccoli extract indicate that positive broccoli plants contain alkaloids, saponins, tannins, and flavonoids. These results are in line with several previous studies which showed the existence of the compound class (Chauhan et al, 2016;Hussain et al, 2019;Mageney et al, 2017;Raiola et al, 2017). The complete phytochemical screening results are presented in Table I.…”

Cessation of bleeding is influenced by many factors including the type of medication used. The use of drugs to stop bleeding can be done in various ways, one of which is the use of traditional medicine. One of the traditional plants that can be used as a stop bleeding is broccoli (Brassica oleracea L. var. italica) which has a fairly high vitamin K content, where is efficacious as hemostatic. This study aims to determine the effect of broccoli on the bleeding time of mice tail cuts. The first group was negative control (Na-CMC), the second group was positive control (tranexamic acid), while groups three, four, and five were broccoli extract dose of 20, 40, and 60 mg/kg BW, respectively. All treatments were given orally for seven days. Bleeding time was calculated from the initial blood loss until the blood stopped (tail bleeding I method) and the data were analyzed with the ANOVA one way test and the post hoc Least Significant Difference (LSD) statistical test. The results showed that there were differences in the time to stop bleeding in the treatment control group at a dose of 20 mg/kg BW (122.60 � 29.535 seconds), 40 mg/kg BW (102.40 � 9.607 seconds) and 60 mg/kg BW (90.40 � 3.845 seconds). From these results, it can be concluded that the extract of broccoli at a dose of 60 mg/kg BW gives the best results as hemostatic, while the effect is almost similar to the positive control group.

“…Average kale total phenolic and anthocyanin content were similar to those reported for white cabbage [19,32]. As for the flavonoid content, this can be assessed in Brassica species by several quantification methods [33]. The spectrophotometric method used in this study, expressing total flavonoid content as quercetin equivalent, was previously used to estimate flavonoid content in broccoli heads, resulting in a range from 4.52 to 9.27 mg quercetin/g dw [34], and in broccoli extracts, resulting in a range from to values from 12.5 to 17.5 mg quercetin/g dw [35].…”

Genetic, Bio-Agronomic, and Nutritional Characterization of Kale (Brassica Oleracea L. var. Acephala) Diversity in Apulia, Southern Italy

Kale (Brassica oleracea L. var. acephala) is a widely appreciated vegetable with a century-old history of cultivation in Italy. The present study was addressed to the collection and characterization of kale germplasm traditionally cultivated in Apulia, Southern Italy, nowadays at risk of genetic erosion. In total, nineteen Apulian kale accessions were acquired. Genotyping by means of simple sequence repeat (SSR) DNA markers led to the identification of highly informative primer combinations and highlighted significant patterns of molecular variation among accessions. Consistently, significant differences were observed with respect to morpho-agronomic traits, including yield and harvesting time, and the content of bioactive compounds, namely total phenols, flavonoids, and anthocyanins, associated with antioxidant activity. Overall, this study led to the establishment of an ex situ collection of great importance to preserve endangered Apulian kale germplasm and to provide seed access to potential growers. Meanwhile, it offers a first characterization of Apulian kale, useful to promote its consumption and valorisation through breeding programmes.

“…Phenolic compounds in vegetables exist in both free and conjugated forms, with the latter generally present in fresh vegetables [ 13 ]. The major classes of phenolic compounds found in cruciferous vegetables are flavonols—mainly O -glycosides of quercetin, kaempferol and isorhamnetin—and hydroxycinnamic acids—mainly ferulic, caffeic, p -coumaric and sinapic acids, found in conjugation with sugars or other hydroxycinnamic acids [ 1 , 14 , 15 , 16 ] and they are used for structural and chemical plant defense strategies [ 1 , 17 ].…”

The phenolic profiles of 12 cruciferous vegetables (pakchoi, choysum, Chinese cabbage, kailan, Brussels sprout, cabbage, cauliflower, broccoli, rocket salad, red cherry radish, daikon radish, and watercress) were studied with UHPLC-MS/MS. Antioxidant activity and total phenolic content (TPC) were also evaluated. A total of 74 phenolic compounds were identified, including 16 hydroxycinnamic acids and derivatives, and 58 flavonoids and derivatives. The main flavonoids identified were glycosylated quercetin, kaempferol and isorhamnetin, and the main hydroxycinnamic acids were ferulic, sinapic, caffeic and p-coumaric acids. Principal component analysis (PCA) revealed that the distribution of phenolic compounds in different genera of cruciferous vegetables was in accordance with their conventional taxonomy. The DPPH, ORAC and TPC values ranged from 1.11 to 9.54 µmoles Trolox equivalent/g FW, 5.34 to 32.92 µmoles Trolox equivalent/g FW, and 0.16 to 1.93 mg gallic acid equivalent/g FW respectively. Spearman’s correlation showed significant (p < 0.05) positive correlations between TPC, flavonoids and antioxidant activity.
