Research ArticleOpen accessIn the abstractTotal Phenolic Composition and Antioxidant Activity of Silver Nanoparticles using Aqueous Extract of Chilca Leaves (Baccharis latifolia)Fernanda Pilaquinga, Camila Granja, Eliza Jara et al.The importance of studying polyphenols as natural antioxidants has encouraged the search for new methods of rapid, simple analysis. The synthesis of silver Nanoparticles (Ag NPs) using plant extracts has been presented as an alternative to determine the presence of polyphenolic compounds. In this study, aqueous extract of chilca (Baccharis latifolia), an endemic plant species from South America known for … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 16 Apr 2021 · 8,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlavonoids from the Zizania latifolia Bracts: Extraction Optimization, Antioxidant Activity and Exploration in Strawberry PreservationTong Wang, Yuzhu Zhang, Lijie Ben et al.Zizania latifolia bracts are Z. latifolia-based agricultural waste materials, distributed in various parts of the world. In the current study, the Response Surface Method (RSM) was used to optimize the cellulase-assisted extraction of Total Flavonoids from Z. latifolia bracts (TFZB). Then, the in vitro antioxidant capacity and the potential effect on strawberry preservation were assessed. The results showed that the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcetylation Process and Antioxidant Activity of a Polysaccharide from Loquat (Eriobotrya japonica) LeavesYiting Xue, Xiao Ding, Ze Zhang et al.Chemical modifications of polysaccharides can provide an opportunity to obtain new agents with possible therapeutic uses. In this study, a water-soluble polysaccharide extracted from Loquat Leaves (coded LLPs) was purified by the column chromatography, which was used to investigate its acetylation process by the acetic anhydride method. The Degree of Substitution (DS) was used as the index, the effect of … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 1 Jan 2021 · 7,056 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Oak Chip Treatments on Quality of Dry White Wines During AgingRongbin Li, Xiaofang Liang, Chunhua Song et al.The objective of the research was to evaluate the effect of different oak chip treatments on quality of Longyan dry white wine during aging. Phenolic substances, antioxidant activity and Cu2+ reduction force were measured. The results showed that wines treated with French oak chips (6 g/L) had significantly higher contents of total phenols (0.083 mg/mL) and flavonoids (0.063 mg/mL), also … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 26 Feb 2020 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractExocellular (1→6)-β-D-Glucan (Lasiodiplodan): Carboxymethylation, Thermal Behavior, Antioxidant and Antimicrobial ActivityThais Vanessa Theis, Gabrielle Cristina Calegari, Vidiany Aparecida Queiroz Santos et al.β-Glucans are biomacromolecules of industrial interest for its biological and technological properties, including ability to modify the rheology of food systems and different biological functionalities. In this study, lasiodiplodan an exocellular polysaccharide of the (1→6)-β-D-glucan type produced by the fungus Lasiodiplodia theobromae MMPI was obtained in a bench-scale bioreactor operated in discontinuous mode. Lasiodiplodan produced was derivatized by carboxymethylation and … …American Journal of Immunology, Vol. 13, Issue 1 · 29 Mar 2017 · 8,326 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractOxidative Status of Boar Semen during StorageEraldo Zanella, Ricardo Zanella, Márcia Rósula Poetini et al.The intensification of the use of artificial insemination in the swine industry has increased the interest to develop proper conditions to store semen better for longer periods of time without affecting its fertility. Trolox is a vitamin E analog with antioxidant property to prevent oxidative stress.
