Background. The search for new plant raw material as a potential source of antioxidants is still ongoing. This study aimed to evaluate the antioxidant and antimicrobial capacity of the plant raw material of Crambe spp. during vegetation. Materials and methods. The free radical scavenging activity and molybdenum reducing power of the extracts were used to determine antioxidant activity. The quantification of polyphenol compounds was conducted with Folin-Ciocalteu reagent. Flavonoids and phenolic acids were also determined. The disc diffusion method was used to determine antimicrobial activity. Results. It was determined that the free radical scavenging activity, assessed using the DPPH-method, was 4.38-8.20 mg TE/g DW, the molybdenum reducing power of the extracts was 40.07-129.12 mg TE/g DW, total polyphenol content was 20.24-70.88 mg GAE/g DW, total flavonoid content was 5.73-29.92 mg QE/g DW, and phenolic acid content was 3.00-10.63 mg CAE/g DW. Antimicrobial activity depended on the stage of growth and the part of the plant used. Conclusion. Crambe spp. possess the antioxidant and antimicrobial potential to mean that they could be used in pharmaceutical studies and the food industry.

“…In the early and late experimental period (seven weeks of treatment), biometrics was performed to collect data. Animals fasted for 24 h, were anesthetized using Eugenol 20 mg.L -1 in the water and crambe meal were obtained in our laboratory using the methodology described by Smith et al (1946), with modifications purpose of Lovatto et al (2017).…”

“…To precipitate the protein, the pH of the liquid was then reduced to 4.5 with 1 N HCl. The solution was conditioned under refrigeration (8ºC) over night to promote decantation of the dispersed protein fraction, followed by discarding the supernatant and drying the concentrated protein fraction in an air recirculation oven at 50ºC for approximately 24 hours (Lovatto et al 2017).…”

The objective of this study was to evaluate growth and metabolic parameters of silver catfish fed with protein concentrates of sunflower meal (SMPC) and crambe meal (CrMPC). The study evaluated two levels of substitution, where 25 or 50% of animal protein was replaced with plant-based protein. A total of 300 silver catfish (14 ± 0.26 g) were used in five treatments and three replications, in fifteen 280-liter experimental units. The results were submitted to analysis of variance and the means of the control diet was compared to the remaining treatments by Dunnett's test at 5% significance level. At the end of the trial, no differences were observed for the variables final weight and daily weight gain. However, minor feed conversion was observed in the groups Control and SMPC-25%. Metabolic parameters were analyzed in the plasma and liver, where no significant differences were found for any of the blood parameters analyzed. In the analyzed liver parameters (ammonia, protein, amino acids and ALAT), the liver protein content was lower in fish consuming SMPC-50%, CrMPC-50% and 25% CrMPC diets. The amino acids content was higher in fish receiving the SMPC-25% diet. It can be concluded that sunflower meal protein concentrate is better utilized by fish and more efficient metabolically than crambe meal. This study demonstrated that a newly developed protein concentrate SMPC and CrMPC can effectively replace 25% and 50% the animal protein in a diet free of FM.

“…A great amount of work has been done upon different species of Crambe in order to evaluate their industrial and pharmaceutical importance [17]. For example, Crambe abissinica is the most known species due to the content of oil and amino acids, protein, phenolic compounds [18]. Also, Crambe abyssinica seed oil contains erucic acid (similar to 59 % of C22:1) which is an important building material for the oleochemical industry [19].…”

Objective: The aim of our study was to establish the content of some primary metabolites, such as amino acids in Crambe cordifolia and Crambe koktebelica. The lack of experimental data induced us to determine these compounds. Methods: Crambe cordifolia and Crambe koktebelica leaves were selected as the objects of the study. The amino acids in the raw materials were determined by the HPLC method. Results: The results of the research revealed that the leaves of Crambe cordifolia and Crambe koktebelica contain fifteen and sixteen free amino acids respectively. Among the free amino acids L-histidine was presented in Crambe cordifolia leaves in the greatest amount, its content was 12.19 µg/mg. The content of free L-arginine, L-valine, L-phenylalanine, L-isoleucine was the greatest in Crambe koktebelica leaves, it was 2.23 µg/mg, 2.04 µg/mg, 1.74 µg/mg, 1.50 µg/mg respectively. The content of bound L-glutamic acid, Glycine, L-arginine, L-leucine was the highest in Crambe cordifolia and Crambe koktebelica leaves. Conclusion: The results of the study showed that Crambe cordifolia and Crambe koktebelica can be considered as a source of highly digestible amino acids that can be used to treat some diseases.
