There are two major global morbidity and mortality problems in the health sector: inflammation, which is the physiological process that, in acute and chronic conditions, gradually causes the loss of the body’s functionality, leading to severe damage to health; and microbial diseases, which are caused by pathogenic microorganisms such as bacteria. In the present study, the anti-inflammatory effects of three extracts of mesquite (Prosopis laevigata)n-hexane (PH), dichloromethane (PD), and methanol (PM)—were assessed in a mouse model of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ear oedema, and the antimicrobial effects against 14 microorganisms were assessed using the broth microdilution method. The extracts inhibited ear oedema by 60.81% (PH), 75.96% (PD), and 60.29% (PM). The most active anti-inflammatory extract (PD) was fractionated through chromatography, and three fractions (PDR3, PDR6, and PDR7) were evaluated. One of the most active fractions (PDR7) was purified via column chromatography, and ethyl veratrate (VE, 1) was isolated and identified. VE inhibited ear oedema by 85.1%. The anti-inflammatory effect is evidenced by the quantification of two pro-inflammatory cytokines (IL-10 and TNF-α). The PD extract, the PDR7 fraction, and the compound present an IL-10 concentration of 11.8, 18.9, and 36.5 pg/mg of protein, values significantly higher than the group that received only phorbol ester (* p < 0.05). These treatments also significantly decreased the concentration of TNF-α (* p < 0.05) to 197.6, 241.9, and 247.0 pg/mg protein, respectively. The PM extract showed the most pronounced antimicrobial effect, with a minimum inhibitory concentration (MIC) of <12.5 µg/mL for almost all the 14 tested strains, followed by the PD and PH extracts. Chromatographic fractionation of the PM extract yielded the PMR6, PMR7, and PMR10 fractions that inhibited all tested microorganisms with a MIC between 6.25 and 200 µg/mL. Compound 1 was active on five strains, with a concentration between 2 and 8 µg/mL. High-performance liquid chromatography analysis and comparison with commercial standards allowed for the identification of rutin (2) and quercetin 3-O-glucoside (3). Gas chromatography–mass spectrometry analysis of the PH and PD extracts allowed for the identification of fatty acids, terpenes, and phenols. Full article

The increasing emission of greenhouse gases that comes with the rise in industrialization is harmful to the environment. Thus, finding new renewable energy sources is becoming increasingly important in the energy field. One such renewable energy source is biomass, which provides valuable energy carriers—for example, biofuels. The objective of this work was to evaluate the release of total reducing sugars (TRSs) from mesquite pod seed hulls by chemical and enzymatic hydrolysis. The husks were crushed and separated by screens (#16, #30 and #50). The effect of hydrolysis time (10, 20, and 30 min) and sulfuric acid concentration (0, 0.25, and 0.5 N) was analyzed. The #50 mesh showed the highest TRS release, increasing from 3.19 to 17.49 g/L as the reaction time was extended. Additionally, enzymatic hydrolysis with endo-1, 4-β-xylanase and β-glucanase enzymes was evaluated on the solid and liquid fractions obtained. Statistical analysis with Design Expert showed that, for the solid fractions, after 31 h there were no significant differences, reaching 79.46 g/L TRS. In the liquid fractions, the TRS released reached 113.37 g/L after 54 h of enzymatic treatment. The release of TRS by chemical hydrolysis was also modeled with artificial neural networks, considering the particle size, the hydrolysis time, and the sulfuric acid concentration. The coefficient of determination (r2) indicates that the ANNs present a better data fit (r2 > 0.99) to predict the experimental conditions that maximize the study variables. Full article

Mesquite (Prosopis spp.) is one of the main plant representatives in regions with a dry climate, and is a fundamental part of the flora of the Mexican arid, with an indisputable importance from ecological, economic and industrial points of view. However, the restrictive factors of dry climates, as well as genetic variability, are sources of the great diversity of mesquite, so its taxonomy is not yet well defined. The present study seeks to determine the diversity of mesquite in the Mexican semi-desert based on the morphometric characterization of its leaves. Methods: Different leaf parameters such as the number, length and width of the leaflets were recorded in 31 well-marked sites in the area, to obtain measures of central tendency and dispersion, and to determine the differences and similarities between the sites, as well as the groups of homogeneous and heterogeneous taxa. Results: Five taxa were identified, of which there were two varieties (Prosopis glandulosa var. glandulosa and Prosopis reptans var. cinerascens), a pure or typical species (Prosopis laevigata) and two hybrids (Prosopis glandulosa var. glandulosa x Prosopis laevigata and Prosopis laevigata x Prosopis glandulosa var. glandulosa). The discriminant analysis indicated that five variables presented the highest percentage of separation or best separated the taxa, so the study was based on the phenogram with the combination of these five variables: (a) length of middle leaflets, (b) length of upper leaflets, (c) spacing of middle leaflets, (d) length/width relationship of middle leaflets and (e) length/width relationship of middle leaflets. Conclusions: Both the traditional taxonomic classification and the cluster and discriminant analyses reflected the same taxa (Prosopis glandulosa var. glandulosa, Prosopis laevigata and Prosopis reptans var. cinerascens) and the existence of hybridization between Prosopis glandulosa var. glandulosa and Prosopis laevigata.

Mesquite (Prosopis laevigata) is a legume tree widely distributed in Aridoamerica. The mature fruit of this legume is a pod, which is currently underutilized and has high nutritional potential. In the present work, mesquite seed flour is described in terms of its nutritional value, as well as the effect of extrusion cooking on its bioactive components. Mesquite seed flour is rich in fiber (7.73 g/100 g) and protein (36.51 g/100 g), with valine as the only limiting amino acid. Total phenolic compound contents in raw and extruded seed flour were 6.68 and 6.46 mg of gallic acid equivalents/g (mg GAE/g), respectively. 2-2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity values in raw and extruded seed flour were 9.11 and 9.32 mg of ascorbic acid equivalent/g (mg AAE/g), respectively. The absorbance at 290 nm, as an indicator of generation of Maillard reaction product (MRP), was the same for raw and extruded samples. Apigenin was the only flavonoid found in mesquite seed flour (41.6 mg/kg) and was stable in the extrusion process. The water absorption index (WAI) and water solubility index (WSI) were changed significantly during extrusion. The expansion of mesquite seed flour extrudates was null due to the high protein and fiber content in the sample. Extrusion cooking of mesquite seed flour is a useful form of technology for the industrialization of this underutilized and nutritionally valuable legume. Full article
