Research ArticleOpen accessEvery word in the titleCharacterization of Crude Polyphenol Oxidase Activity in Buckwheat SproutsYuedong Song, Yangfang Zhang, Yilin Wang et al.Buckwheat sprouts can not only effectively reduce the trypsin inhibitor in buckwheat grain, but also improve the content of bioactive ingredients such as flavonoids and other effective components. However, Polyphenol Oxidase (PPO) in buckwheat sprouts causes browning of food, which limits the application of buckwheat sprouts in food. In addressing this problem, studying the characteristics of PPO in buckwheat sprouts … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 25 Jun 2021 · 6,486 accessesView PDFCite

Polyphenols Cicatrizing Activity on Experimental Thermal Burns in New Zealand RabbitsSihem Khadri, Nafissa Boutefnouchet, Youcef Hadef, Zouhir DjerrouThe present study aimed to evaluate the healing properties of the medicinal plant Cytisus triflorus widely used in the traditional treatment of wound healing. The principle of study is the application of the polyphenol extract of this plant prepared with vaseline in the form of a dermal ointment on thermal burns of second deep degree (circular of 379.94 mm2 in … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 12 May 2018 · 7,524 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDistribution of Polyphenol Oxidase in some Cruciferae VegetablesAndi Nur Faidah Rahman, Februadi Bastian, Jumriah Langkong, Shuji FujitaEnzymatic oxidation of polyphenolic compounds in damaged tissue of many fruits and vegetables induced undesirable browning as results in decreased marketability of products. A new type of polyphenol oxidase (PPO) that is “Phloroglucinol Oxidase (PhO)” have been reported in turnip and cabbage, and the purified enzymes also had strong peroxidase (POD) activity. Distribution of PPO from different plant source of … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 31 Jan 2016 · 8,093 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRESPONSE SURFACE METHODOLOGY ANALYSIS OF POLYPHENOL RECOVERY FROM ARTICHOKE WASTEAntonio ZuorroLarge amounts of a solid waste consisting mainly of outer bracts and stems are produced from the industrial processing of artichokes. In this study, the recovery of polyphenols from the two waste components was investigated. Extraction experiments were carried outby an environmentally friendly procedure using aqueous ethanol as solvent. The total polyphenol content, expressed as mg of GAE per g … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 3 Jul 2014 · 7,189 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Heirloom Tomato Polyphenol Extracts on Expression of Inflammation Genes in BovineKwaku Gyenai, Nona Mikiashvili, Hamid Ismail, Mulumebet WorkuThe effect of tomato on diseases of economic importance continues to be of broad interest. To evaluate these relationships, the effect of crude extracts of Cherokee purple tomato on pro-inflammatory genes and cytokines were evaluated. Neutrophils from three Holstein Fresian cows were treated with Phosphate Buffered Saline (PBS) or E. coli O111-B4 Lipopolysaccharide (LPS). Treated cells were exposed to different … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 3 · 25 Aug 2012 · 8,377 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOverview of Membrane Processes for the Recovery of Polyphenols from Olive Mill WastewaterOmpe Aime Mudimu, Martin Peters, Florian Brauner, Gerd BraunProblem statement: Olive Mill Wastewater (OMW) is an ambivalent by-product of the olive oil production, which appears in huge amounts every year after the olive-harvest in the production countries, mainly in the Mediterranean region. OMW is characterized by a high organic load and i.a. contains considerable amounts of phytotoxical polyphenols, which cause important environmental problems. Approach: Due to their antioxidant … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 27 Mar 2012 · 8,544 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparative Extraction of Pectic and Polyphenols from Mexican Lime Pomace and BagasseDaniela Sanchez-Aldana, Cristobal Noe Aguilar, Guadalupe Virginia Nevarez-Moorillon, Juan Carlos Contreras EsquivelMexican lime bagasse and pomace are rich in pectin and they also represent an important source of value-added compounds such as polyphenols. Two different options for the combined recovery of pectin and phenolic compounds from Mexican lime bagasse and pomace, two byproducts of industrial lime processing, were developed. Conventional and microwave-assisted extraction methods were used. All pectic extracts presented a … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 29 Oct 2013 · 7,804 accessesView PDFCite
Research ArticleOpen accessIn the keywordsWhat is Xenohormesis?Joseph A. Baur, David A. SinclairPolyphenols such as resveratrol and quercetin, which are produced by stressed plants, activate sirtuin enzymes and extend the lifespan of fungi and animals, ostensibly by mimicking the beneficial effects of caloric restriction. This observation raises an interesting question: Why should foreign molecules that are non-nutritive and seemingly unrelated to any endogenous molecule modulate the same biochemical pathways that mediate the … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 10,386 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQualitative Analysis of the Chemical Composition of Cinnamomum tamala leaves and Biological ActivityQianwen Gong, Pin Chen, Linyang Wang, Shuge TianCinnamomum tamala (Buch.-Ham.) Nees and Ebermaier. (Lauraceae) is a less explored medicinal plant in Uyghur medicine, with limited knowledge about its non-volatile compounds. We utilized chemical pre-screening in conjunction with UPLC-Q-Orbitrap-MS to analyze the phytochemical makeup of C. tamala leaves. Total polyphenols were measured using the Folin-Ciocalteu method, while total flavonoids were quantified through NaNO2-Al (NO3)3 colorimetric analysis across four … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 659 accessesView PDFCite
