“…60 Another study on the protein content of spinach leaves treated with ZnO NPs showed a significant increase at higher concentrations in comparison with control. 39 It is important to note that in this study the average protein content found in treated seeds is slightly higher (∼3−6%) than that reported by Danlami et al 53 Nutritional properties of seed oil depend on the fatty acid composition, mainly the quantity of oleic, linoleic, and erucic acids, which in turn has great importance in human nutrition. 61,62 Among them, erucic acid is the most vital fatty acid present in the genus Brassica.…”

Black mustard (Brassica nigra) was grown in pots amended with 41 nm ZnO (200–600 mg/kg soil) and 47 nm CuO (12.5–50 mg/kg soil) nanoparticles (NPs) to analyze growth response and yield characteristics. B. nigra seed germination was not affected by CuO NPs, but significant toxicity was observed by ZnO NP treatment. Both NPs significantly increased the growth profile of B. nigra, i.e., the stem height, number of leaves, average leaf area, number of branches, and number of nodes per plant. Application of ZnO and CuO NPs brought a significant dose-dependent decrease in primary root length; however, the number of secondary roots increased in the presence of CuO NPs. The average number of flowers and pods per plant significantly increased in the presence of CuO NPs. The seed yield, average seed weight per plant, and seed diameter parameters were observed to be better in the presence of CuO NPs as compared with ZnO NPs. Total protein contents and glucosinolates increased in the seeds grown in the NP-amended soil, while total oil contents decreased. Oil analysis depicted that oleic acid and linolenic acid percentage decreased while erucic acid percentage increased in seeds in the presence of both NPs in the soil. An atomic absorption spectrophotometer showed accumulation of Cu and Zn in B. nigra in the following order: root > stem > leaves > seeds. The study concludes that CuO and ZnO NPs have detrimental effect on the B. nigra plant and yield. The release of NPs and type of metal in NPs might also have a positive effect on the plant; however, their concentration in the soil also matters.

“…However, DSMs contain other substances (proteins, residual oils, and phenolic compounds), which normally the bee assumes by feeding on the pollen with positive effects on health, learning and other cognitive functions and that may contribute to the global effect of the formulation [ 70 , 71 , 72 ]. In the case of E. sativa and B. nigra DSMs, the protein component is rich in sulfur-containing amino acids while the erucic acid, a compound recognized as toxic for the humans [ 73 , 74 , 75 ], but of unknown effects on the bees, is the most represented fatty acid in the residual oil. Nevertheless, oils from E. sativa and B. nigra showed respectively antifungal and antibacterial activity [ 76 , 77 ], which may complete the ITC effect.…”

Seed Meals from Brassica nigra and Eruca sativa Control Artificial Nosema ceranae Infections in Apis mellifera

et al. 2021

Nosema ceranae is a widespread parasite responsible for nosemosis Type C in Apis mellifera honey bees, reducing colony survival. The antibiotic fumagillin is the only commercial treatment available, but concerns are emerging about its persistence, safety, and pathogen resistance. The use of natural substances from Brassicaceae defatted seed meals (DSMs) with known antimicrobial and antioxidant properties was explored. Artificially infected bees were fed for 8 days with candies enriched with two concentrations, 2% and 4%, of two DSMs from Brassica nigra and Eruca sativa, containing a known amount of different glucosinolates (GSLs). The food palatability, GSL intake, bee survival, and treatment effects on N. ceranae spore counts were evaluated. Food consumption was higher for the two 2% DSM patties, for both B. nigra and E. sativa, but the GSL intake did not increase by increasing DSM to 4%, due to the resulting lower palatability. The 2% B. nigra patty decreased the bee mortality, while the higher concentration had a toxic effect. The N. ceranae control was significant for all formulates with respect to the untreated control (312,192.6 +/− 14,443.4 s.e.), and was higher for 4% B. nigra (120,366.3 +/− 13,307.1 s.e.). GSL hydrolysis products, the isothiocyanates, were detected and quantified in bee gut tissues. Brassicaceae DSMs showed promising results for their nutraceutical and protective effects on bees artificially infected with N. ceranae spores at the laboratory level. Trials in the field should confirm these results.

“…The phytochemical properties and antioxidant potential of Brassica plants make them the preferred candidates for nutritional and pharmaceutical applications. Due to the presence of these compounds, Brassica plants show biological activities against various diseases and have been found to be effective in treating various diseases in human [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] .…”

To find out different qualitative and quantitative phytochemical properties, it's in-vitro antioxidant properties and peroxidase activity of Brassica juncea var. Rugosa (record tro-50197928) with fresh and sequential solvent extracts. Methods: The leaf sample of Brassica juncea var. rugosa was collected from Manipur and the sample was dried. The dried powder was extracted using Soxhlet with the sequential solvent of non-polar to polar. Preliminary phytochemical analysis for proteins, carbohydrates, phenols, alkaloids, flavonoids, tannins, saponins, steroids, terpenoids, and quantitative estimation for total proteins, carbohydrates, alkaloids, phenols, flavonoids, and tannins. In-vitro, antioxidant activity was analyzed by using DPPH assay. Peroxidase activity was also checked. Results: The plant extracts showed the presence of a considerable amount of total alkaloids, total phenols, total flavonoids, total tannins, total proteins, total carbohydrates. The plant extracts also showed high antioxidant and peroxidase activity. Conclusions: From the study, we can conclude that the plant Brassica juncea var. rugosa has many important secondary metabolites and it has a potential for strong antioxidants. INTRODUCTION: The giant-leafed mustard, also known as "Japanese mustard" or 'Head mustard'', (B. juncea var. rugosa) belonging to the family Cruciferae has broad reddish-purple variegated leaves. It is an essential vegetable crop in Manipur. It is commonly known as 'Hangam' in Manipur. It is mainly grown in winter season as kitchen garden crops in most of the houses of Manipur, India. Usually the plant grows up to 60 cm in height. The plant requires cold climatic conditions and welldrained moist soil. It can grow in semi-shade or no shade 1 .
