Abstract
Bagasse is a byproduct generated during the process of making the traditional Andean drink named “chicha de jora” in Peru, which is a potential source for the extraction of ferulated arabinoxylan (FAX). The aim of this study was to extract and characterize the FAX from bagasse and determine its antioxidant and antihyperglycemic capacity in vitro. As a result, FAX of molecular weight ≥3.5 kDa presented moisture content, pH, total ash, proteins, and total phenolic content with values of 8.00%, 5.81, 2.68%, 3.78%, and 5.72 mg EAG/g, respectively. Thin-layer chromatography identified the monosaccharides L-arabinose and D-xylose. HPLC-MS/MS analysis of FAX confirmed the presence of methyl-pentofuranosides or methyl-pentopyranosides. The FT-IR spectrum presented characteristic bands of FAX. The FAX showed antioxidant capacity determined by the DPPH assay (IC50 = 6.59 mg/mL and TEAC = 7.7844 μmol/g sample), ABTS (IC50 = 6.50 mg/mL and TEAC 35.34 μmol/g sample), and FRAP (14.08 μmol AA/g and 36.63 μmol FeSO4/g). On the other hand, FAX showed glucose adsorption capacity, inhibition of glucose diffusion, and inhibition of the enzyme α-amylase (IC50 = 4.73 mg/mL). The results showed that the FAX extracted from the bagasse generated during the production of the “chicha de jora” has in vitro antioxidant and antihyperglycemic capacity.

Impact of LFGD (Ar+O 2) plasma on seed surface, germination, plant growth, productivity and nutritional composition of maize ( Zea mays L.). Heliyon 2021; 7:e06458. [PMID: 33768173 PMCID: PMC7980070 DOI: 10.1016/j.heliyon.2021.e06458] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 12/31/2020] [Accepted: 03/04/2021] [Indexed: 12/20/2022] Open
Abstract
In this present study conducted with the LFGD (Low-Frequency Glow Discharge) (Ar + O2) plasma treated maize seeds, to inspect the effect on seed surface modifications, seed germination, growth, development, productivity and nutritional compositions of maize plants. This study reported that LFGD (Ar + O2) plasma treated maize seeds have a potential effect to change its smooth seed surfaces and, it becomes rougher. It also enhances the seed germination rate up to (15.88%), which might help to increase the shoot length (33.42%), root length (10.67%), stem diameter (13.37%), total chlorophyll content (46.93%), total soluble protein (52.48%), total soluble phenol (21.68%) and sugar (1.62%) concentrations in respect controls of our experimental plants. For this reason, the acceptable treatment duration for maize seeds were 30sec, 60sec, 90sec and 120sec. After treatment, the plants exhibited a significant increase in CAT, SOD, APX and GR activities in the leaves and roots, and also significantly changes in H2O2 (208.33 ± 5.87μ molg-1 FW) in the leaves and (61.13 ± 1.72μ molg-1 FW) in the roots, NO was (369.24 ± 213.19μ molg-1FW) and (1094.23 ± 135.44μ molg-1FW) in the leaves and roots. LFGD plasma treatment also contributed to enhancement of productivity (1.27%), nutritional (moisture, ash, fat, and crude fiber) compositions, and iron and zinc micro-nutrition concentrations of maize. From this research, LFGD (Ar + O2) plasma treatment showed a potential impact on the maize cultivation system, which is very effective tools and both in nationally and internationally alter the conventional cultivation system of maize. Because it promotes seed surface modification, improved germination rate, shoot length, root length, chlorophyll content, some of the growths related enzymatic activity, nutrient composition, iron, and zinc micro-nutrients and the productivity of maize.

Abstract
Salicornia neei halophyte extends in Argentina seashores. To envisage potential applications, cell wall sequential extraction performed on dry plant yielded 1.1, 2.4, 0.3 and 0.9% of pectin fractions respectively extracted by room temperature water, 90 °C-water, CDTA and Na2CO3. They contained 21-33% uronic acids (UA) with low degree of methylation and 0.5-1.2 M ratios of neutral sugars to UA. High arabinose level suggests that long arabinan side-chains maintain cell wall flexibility in water deficit. Fractions also contained 10-36% of proteins. The KOH-soluble fractions (4.3%) were mainly arabinoxylans. At 2.0% w/v, pectin fractions developed "weak gel"-type networks with Ca2+, while arabinoxylans generated "dilute solutions". Cellulose (28%) and lignin (45.1%) were the main biopolymers in the final residue, which showed low water swelling capacity (3.6 mL/g) due to lignin, increasing when arabinoxylans were also present. Phenolics (9.8%) were mainly water-extractable. Salicornia is a source of biopolymers and antioxidants potentially useful for food applications.
