The authenticity of genotypes of white cabbage (Brassica oleracea var. capitata f. alba) cultivar ‘Varaždinski’, which originate from three eco-geographical regions, has been evaluated using ...molecular (RAPD) and chemometric approach. RAPD analyses confirmed intra-cultivar variability depending on the seed origin. At least three clusters were distinguished and organized in two groups and one subgroup (groups I and HR with subgroup SLO), which are mainly in agreement with eco-geographical location of the seed producers. Phytochemical analysis showed statistically significant variations in pigment and polyphenolic contents as well as in antioxidant capacities of the selected genotypes. The principle component analysis (PCA) visualized relationship among genotypes, phytochemical contents and antioxidant capacity. It revealed that the first two components represented 87% of the total variability in investigated parameters. Accordingly, genotypes were clustered in agreement with eco-geographical regions of seed producers. Analysis of seed storage proteins did not show significant differences among genotypes of interest. The authenticity of selected genotypes of white cabbage cv. ‘Varaždinski’ was discussed based on the molecular and phytochemical diversity.
•6 cabbage genotypes cv. Varaždinski were analyzed by genetic and chemometric approach.•RAPD revealed 3 clusters correlating with geographical location of seed origin.•PCA visualized correlation between phytochemical parameters and genotypes.•Results confirmed intra-cultivar diversity of cv. Varaždinski considering seed origin.
Brassica oleracea var. capitata f. alba (white cabbage) is a cruciferous vegetable used as a vegetable and traditional medicine all over the world. Different preparation from several parts of the ...plant- roots, shoots, leaves, and the whole plant are used to treat a wide range of diseases, including diabetes, cancer, gastric, inflammation, hypertension, hypercholesterolemia, bacterial, oxidation, and obesity.
The aim of the current review is to evaluate the botany, distribution, traditional uses, phytochemistry, and pharmacological activities of B. oleracea var. capitata. Moreover, this review will guide to fill the existing gaps in information and highlight additional research prospects in the field of phytochemistry and pharmacology.
Various resources, including research papers, review papers, books, and reports, were collected to obtain overall information on Brassica oleracea var. capitata, which were obtained by an online search of worldwide-accepted scientific databases. Phytochemical constituents' structures were drawn by ChemDraw software.
About 72 isolated phytochemical compounds of B. oleracea var. capitata have been collected from different articles, which included different types of compounds such as alkaloids, flavonoids, organic acids, glucosinolates, steroids, hydrocarbons, etc. Crude extracts and phytoconstituents of B. oleracea var. capitata have various pharmacological effects, including antidiabetic, anticancer, antihypertensive, anticholesterolemic, antioxidant, anti-inflammatory, antibacterial, anti-obesity, anticoagulant, and hepatoprotective. We have enlisted all these pharmacological data along with all the phytochemical constituents of Brassica oleracea var. capitata.
The study was focused on the traditional uses, pharmacological activities, and phytochemistry of Brassica oleracea var. capitata, and the findings indicated that B. oleracea var. capitata is an important medicinal plant that shows several pharmacological effects. We hope our review of this plant will provide more basic and useful information and fill some research gaps for further investigation and drug design. Although we found some important traditional uses and pharmacological activities of Brassica oleracea var. capitata, there is insufficient work in the field of phytochemical activities.
Context: There have been no reports of the extraction of essential oil (EO) from white cabbage Brassica oleracea L. var. capitata (L.) Alef. f. alba DC. (Brassicaceae) (Bocfal) or its chemical ...composition, antioxidant activity, or hepatoprotective effects.
Objective: To extract Bocfal EO, to identify and quantify its chemical components, to assess their antioxidant capacity, and to evaluate the hepatoprotective properties of Bocfal EO.
Materials and methods: Bocfal EO was obtained using hydrodistillation (200 mm Hg/58 °C). The chemical composition was analyzed using GC-MS and was quantified using GC-FID. The antioxidant activity of Bocfal EO and its main constituents was evaluated using TBARS in rat brain homogenates. A Bocfal EO hepatoprotective effect (192 mg/kg) on acute carbon tetrachloride (CT)-induced liver damage was determined in rats using biochemical markers and histological analysis. Diallyl disulphide (DADS) (1 mmol/kg) was used as a control for comparison.
Results: Bocfal EO contained organic polysulphides (OPSs), such as dimethyl trisulphide (DMTS) 65.43 ± 4.92% and dimethyl disulphide (DMDS) 19.29 ± 2.16% as major constituents. Bocfal EO and DMTS were found to be potent TBARS inhibitors with IC
50
values of 0.51 and 3 mg/L, respectively. Bocfal EO demonstrated better hepatoprotective properties than did DADS (p < 0.05), although both slightly affected the hepatic parenchyma per se, as observed using histopathology.
Discussion and conclusion: The antioxidant properties of Bocfal EO and DMTS may be the mechanism of hepatoprotective action; the parenchymal disturbances by Bocfal EO or DADS alone may be related to the high doses used.
Productivity and growth of vegetables planted as intercrops were investigated in a three-year experiment (2007-2009) according to organic farming rules in the northeast of Slovenia. White cabbage ...(Brassica oleracea var. capitata f. alba) as the main crop was planted together with intercrops: head lettuce (Lactuca sativa var. capitata), bush bean (Phaseolus vulgaris), red beet (Beta vulgaris ssp. rubra), tomato (Lycopersicum esculentum), leek (Allium porrum), and celery (Apium graveolens). The market yield of cabbage as a sole crop (41.07 t ha-1) did not differ to intercropping production with salad and red beet; yields of cabbage in intercropping with celery, leek, beans and tomato were significantly lower. All intercrops had land equivalent ratios (LER) >1.00 and the highest LER (1.62) was reached in cabbage and tomato intercropping due to the same density of tomato as an intercrop and as a sole crop. The intercropping production of white cabbage with the studied vegetables is more productive than sole cropping in terms of land use efficiency.
As the importance of information about food quality dependent on agriculture production methods has increased among many consumers, some internal quality parameters of white cabbage were investigated ...on samples from a field experiment carried out in the northeast of Slovenia. In 2008, sensory properties, mineral composition, and content of vitamin C were investigated in the samples from the control treatment and from conventional, integrated, organic, and bio-dynamic farming systems. Farming system significantly influenced the content of iron, zinc, phosphorous, potassium, manganese, and ash in fresh and dry samples, magnesium only in fresh and sodium only in dry samples. The content of ascorbic acid was higher in samples from control and biodynamic treatments compared to other three treatments. Untrained evaluators scored their preference for four characteristics (colour, odour, taste, and overall acceptability) using a nine-point hedonic scale. Statistically significant differences were shown for all characteristics. According to the overall acceptability, samples were ranked control = integrated = organic > conventional = biodynamic.
