“…The composition of saturated fatty acids is 19.7% and 19.4% with a higher proportion of palmitic acid 10.2% and 11.2%, followed by stearic acid 8.9% and 7.4%, respectively. These results are in accordance with the scientific literature where oleic, linoleic, palmitic and stearic fatty acids are the most abundant in Jatropha curcas oil, with oleic acid the highest proportion [47,48]. This composition is also presented in other varieties studied in Mexico by Martínez-Herrera et al and Sánchez-Arreola et al [20,33].…”

The objective of this study is to identify Mexican nontoxic ecotypes of Jatropha curcas with potential for a sustainable agriculture practice to produce biodiesel and food products through a methodology and criteria of sustainability. In a rural region of Morelos state in central México, nine Mexican ecotypes of Jatropha curcas were evaluated in an experimental plantation with minimal water resources and fertilization. The experimental trial was assessed in terms of (1) toxicity, (2) growth and survival of the plants, (3) yield of seed, (4) residual biomass production, (5) oil characteristics for biodiesel production, (6) nutrimental properties of the seeds, and (7) changes in the chemical properties of the soil. Finally, two outstanding nontoxic ecotypes were identified as the most suitable for the establishment of Jatropha curcas crops to produce biodiesel and, at the same time, for food products using the de-oiled endosperm cake, for energy production from the residual biomass and for improvement of soil properties in marginal lands of rural regions of Morelos state.

“…1S), a signal at 7.34 ppm characteristic of the benzyl aromatic protons could be seen. Likewise, characteristic signals of fatty acids mixtures were observed, which were compared with the data reported [32]. These are included in ▶Table 1S, in which the chemical shifts of the n-heptane extract were observed.…”

Although Tropaeolum tuberosum tubers have been consumed cooked as a folk remedy for the treatment of skin, lungs, liver and kidneys diseases, these uses have very limited scientific basis. Therefore, this article develops a phytochemical analysis of the yellow tubers of T. tuberosum with the objective to assess whether the isolated compounds have anti-inflammatory potential in the CCD-1109Sk, MRC-5 and RWPE-1 cell lines. We performed an extraction of T. tuberosum tubers using different organic solvents, followed by a bioguided chromatographic separation. Four macamides were identified by LC/MS techniques, but only N-benzyllinoleamide (1) and N-benzyloleamide (2) were isolated and elucidated by NMR/MS techniques, given that they were present in a larger proportion in the tubers. The anti-inflammatory potential of macamides was evaluated by the inhibition of NF-κB and STAT3 activation. Both compounds displayed inhibition of NF-κB activation with IC50 values of 2.28±0.54 µM; 3.66±0.34 µM and 4.48±0.29 µM for compound (1) and 6.50±0.75 µM; 7.74±0.19 µM and 8.37 ±0.09 µM for compound (2) in CCD-1109Sk, MRC-5 and RWPE-1 cell lines, respectively. Moreover, both compounds inhibited the STAT3 activation with IC50 of 0.61±0.76 µM; 1.24±0.05 µM and 2.10±0.12 µM for compound (1) and 5.49±0.31 µM; 7.73 ±0.94 µM and 7.79±0.30 µM for compound (2). Therefore, isolated macamides of T. tuberosum tubers showed promising anti-inflammatory effects, suggesting a possible beneficial use to combat inflammatory processes of skin, lung and prostate.

“…The physical and chemical properties of biofuels are similar to those of diesel made from petroleum, and can be used in pure or in mixed form without altering the operation of the diesel engine (ANDRADE et al, 2017). Biodiesel is among the principal biofuels used in the world, and Brazil has the capacity for its production using various oil species, such as the physic nut (Jatropha curcas L.) (SOUZA et al, 2018).…”

Determining the chemical composition of seeds of the physic nut (Jatropha curcas L.) is of great importance for the species due to the oil content of the seeds (the principal trait of interest). Identifying promising genotypes with selectable seed traits is one of the strategies adopted in breeding the physic nut in order to increase the yield and quality of the oil. Therefore, the aim of this study was to determine the chemical composition of seed traits in ten half-sibling progeny of the physic nut, and to identify which progeny have good genetic performance for transmission to the offspring. The experimental design was completely randomised, with ten treatments and four replications. The treatments were represented by seeds from half-sibling progeny in which the carbohydrate, protein and lipid content, and the composition of the fatty acids were evaluated. The genetic parameters and the gains from their selection were predicted for the principal seed traits using mixed-model analysis, including REML (restricted maximum likelihood) and BLUP (best linear unbiased prediction). The physic-nut seeds showed an average dry matter (DM) concentration of 60 mg g-1 carbohydrates, 42 mg g-1 protein and 142 mg g-1 total lipids. Unsaturated fatty acids represented more than 85% of the total fatty acid composition, with the oil classified as oleic-linoleic. Considering the predictions of the genetic parameters, the lipid traits can be selected for the purpose of breeding, resulting in genetic progress in the yield and quality of physic-nut oil.
