Abstract Objectives The objective of this work was to evaluate the potential of common bean phenolic extract to exert anti-aging and antioxidant effect by inhibiting the collagenase, elastase, tyrosinase enzymes and free radicals. Methods 18 varieties of common bean (Phaseolus vulgaris L.) from Chiapas, Mexico, were analyzed for total phenolic content (TPC) and total anthocyanin content (ACN). Supercritical fluid (SCF) and leaching extractions were used for phenolic compounds extraction. Antioxidant capacity was evaluated using DPPH and ABTS scavenging assay. The inhibitory potential of the extract was evaluated for tyrosinase from mushroom, collagenase type-1 from Clostridium histolycum and elastase from porcine pancreas enzymes. Results The TPC ranged from 3.8–34.33 mg GAE/g coat and ACN ranged from 0.04–9.41 mg C3GE/g coat among the 18 common bean varieties (P < 0.05). The cultivar selected for this study was black bean with a TPC of 27.45 ± 0.7 mg GAE/g coat and ACN of 5.3 ± 0.1 mg C3GE/g coat. The best extraction conditions for the obtention of phenolic compounds and anthocyanins were SCF water-ethanol 50% as cosolvent, obtaining 66.60 ± 7.4 mg GAE/g coat (TPC) and 7.3 ± 0.6 mg C3GE/g coat (ACN). TPC and ACN content between each extraction process were statistically different (P < 0.05). For DPPH scavenging assay the IC50 for the black bean extract was 0.32 ± 0.01 mg GAE/g coat, and 0.40 ± 0.03 mg GAE/g coat for ABTS assay. Finally, the IC50 for the enzymatic inhibition assays of tyrosinase, collagenase and elastase were 10.44 ± 1.32, 8.33 ± 0.65 and 0.11 ± 0.02 mg GAE/g coat, respectively. Conclusions Black bean (Phaseolus vulgaris L.) extract presents high antioxidant capacity and inhibitory potential for tyrosinase and metalloproteinases such as collagenase and elastase. Black bean phenolic extracts could be used in cosmeceutical products related to preventing oxidative stress and aging.

The present study investigated angiotensin-I-converting enzyme (ACE) inhibitory and antioxidant activities of barbel muscle protein hydrolysate prepared with Alcalase. The barbel muscle protein hydrolysate displayed a high ACE inhibitory activity (CI50=0.92 mg/mL). The antioxidant activities of protein hydrolysate at different concentrations were evaluated using variousin vitroantioxidant assays, including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical method and reducing power assay. The barbel muscle protein hydrolysate exhibited an important radical scavenging effect and reducing power. These results obtained byin vitrosystems obviously established the antioxidant potency of barbel hydrolysate to donate electron or hydrogen atom to reduce the free radical. Furthermore, these bioactive substances can be exploited into functional foods or used as source of nutraceuticals.

Experimental Plots

The objective was to evaluate the minimum size of experimental plots for the common bean (Phaseolus vulgaris L.) using the modified maximum curvature method. The experiment consisted of a uniformity trial with the cultivar BRSFC-402 sown at a spacing of 0.5 m between plant rows and 10 plants per meter within the row. 20 central rows measuring 20 m in length were considered for measurements, totaling 4,000 plants on an area of 200 m2. Final bean stand (FS), mean number of pods per plant (NPP), mean number of grain per pod (NGP), mean 100-grain weight (M100), and grain yield (kg ha-1) were evaluated. At evaluations, each row with 10 plants was considered a basic unit (0.5 m2), amounting to 400 basic units whose dimensions were combined into 14 plot shapes.  The methods of relative information and modified maximum curvature were used to obtain the best shape and the most appropriate plot size, respectively, for experimental evaluation with common bean. Using these methods, and considering that the optimum plot should enable an efficient evaluation of all evaluated characteristics, the appropriate plot size was five UB (25 plants) in the format with five rows x one UB per row. Highlights Support for experimental evaluation of common beans under edaphoclimatic conditions in the northern region of Minas Gerais Experimental plots with five basic units ensure maximum precision for joint evaluation of the main phenotypic descriptors of common beans. The characteristics mass of 100 grains and productivity were associated with the smallest and the largest plot sizes, respectively.

Objective: The current investigation was conducted to evaluate phenol and flavonoid contents, antibacterial, antioxidant and antihypertensive potentials of three extracts of Margotia gummifera aerial parts. Methods: The antibacterial effect was assessed using wells agar diffusion method against 11 strains. The antioxidant effect was evaluated using different methods, 2, 2-diphenyl-1-picrylhydrazyl, total antioxidant capacity, ferric reducing ability power, cupric reducing antioxidant capacity and β-carotene/linoleic acid bleaching assay. The antihypertensive activity was performed using hippuryl-histidyl-leucine substrates. Results: The highest yield was obtained by hydro-methanolic extract, 19.801 %, however ethyl acetate extract seemed to be rich on phenolic and flavonoid compounds comparing to other extracts, 822.14±69.10 mg GAE g-1 ext. and 117.28±1.80 mg RE g-1 ext., respectively. The high free radical scavenging activity was mentioned in ethyl acetate extract with IC50 of 48.820±1.25 µg/ml. The same extract showed better antioxidant activity in all tested procedures. In antibacterial activity, the hydro-methanolic extract exhibited moderate effect against all tested bacteria except Salmonella enterica and Enterococcus faecalis which gave 18±2.0 and 16±1.0 mm of inhibition, whereas, it seemed to be inactive towards two Gram-negative bacteria. Concerning antihypertensive activity, all extracts can inhibit the Angiotensin-I Converting Enzyme, but the potential effect was given by hydro-methanolic and aqueous extracts, 97.75 % and 96.65 %, respectively. Conclusion: It can be stated that bioactive compounds of Margotia gummifera extracts had different biological activities which confirm their therapeutic uses in traditional medicine.
