Abstract The common bean (Phaseolus vulgaris L.) is a source of nutrients and contains phenolic compounds that act as antioxidants. The aim of the present study was to determine the phenolic compounds and tannins in two bean cultivars (Phaseolus vulgaris L.): the biofortified carioca bean (Pontal) and the common bean (commercial). The antioxidant activity of the phenolic compounds and their fractions was also measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) methods. The thermal processing decreased the phenolic compounds, tannins and the antioxidant activity of beans. The Pontal cultivar exhibited higher levels of phenolic compounds even after cooking. For cooked beans, higher antioxidant activity was observed in the commercial beans by the DPPH method. Regarding to the fractions, in general, lower values of antioxidant activity by DPPH were observed for beans after cooking, except for fraction 6 of the Pontal bean and fraction 3 of the commercial bean. For fraction 4 no significant differences were observed by the ABTS method for both cultivars after thermal processing.

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 objective of this work was to evaluate the efficiency of nitrogen fixing inoculum associated with Co + Mo leaf spray on the common bean grain yield and grain nutrients, cv. FT Nobre. Three dosages of the inoculant (0, 200 and 400 g/50 kg seeds), combined with four Co + Mo leaf spray levels (T0=0,0; T1=4.9,49; T2=7.3,73; and T3=9.7,97 g ha-1 of Co and Mo, respectively) were tested. The grain yield with the use of the inoculant (400 g / 5O kg seed-1) associated with the higher level of Co+Mo (T2 and T3) was very similar to the mineral nitrogen condition fertilizer recommended for the bean (70 kg ha-1 of N). With the increased inoculant dosage, an increase of the protein content and of P and Mg in the grain was also observed. The results indicated that the mineral nitrogen source could be replaced by inoculation of the seeds with Rhizobium tropici combined with Co + Mo leaf spray.
