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 · 6,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolyherbal EMSA ERITIN Blocks Nuclear Factor-Kappa B (NF-κB) and Proinflammatory Cytokines in Irradiated MiceYuyun Ika Christina, Mansur Ibrahim, Muhaimin Rifa’iRadiation therapy is commonly used in cancer treatment that produce deleterious effects, such as normal cell death (apoptotic or necrotic) and suppression of hematopoietic stem cells. This effect was caused by ion rays that can rise to high of free radical. The high of free radical trigger the inflammation of cells. EMSA ERITIN is medicinal herb used as preventative agents … …American Journal of Immunology, Vol. 11, Issue 1 · 29 May 2015 · 7,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Inflammatory, Analgesic and Antioxidant Activities of Allophylus Cobbe LeavesPreeti Jain, Md. Selim Hossain, Kaniz Fatema et al.Allophylus cobbe L. Raeuschel (Family-Sapindaceae) is a medicinal plant used traditionally for the treatment of various health risks like pain, inflammation, ulcers and wounds in Bangladesh. This study determined the polyphenolic compounds and evaluated the analgesic, anti-inflammatory and antioxidant effects of the ethanol extract of Allophylus cobbe leaves. High Performance Liquid Chromatography (HPLC) analysis was used to determine the polyphenolic … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 4 · 27 Jan 2015 · 8,155 accessesView PDFCite
EditorialOpen accessIn the abstractGLUTATHIONE: A POSSIBLE LINK TO AUTOPHAGY IN SYSTEMIC LUPUS ERYTHEMATOSUSDilip Shah, Swapan K. NathIncreased free radical formation and altered redox state are of fundamental importance in the pathogenesis of autoimmune diseases including Systemic Lupus Erythematos (SLE). Free radicals are mainly derived from oxygen (Reactive Oxygen Species/ROS) and nitrogen (Reactive Nitrogen Species/RNS) at mitochondria, cellular membranes and the endoplasmic reticulum membrane as physiological responses to a variety of internal and external stress (Shah et … …American Journal of Immunology, Vol. 10, Issue 3 · 3 Sep 2014 · 12,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Oxidant and Enzyme-Inhibitory Potential of Marine StreptomycesT. Revathy, M. A. Jayasri, K. SuthindhiranMarine actinomycetes are potential source for the discovery of novel compounds and enzymes. Though extensive research on marine actinomycetes is underway globally, the actinomycetes research from Indian marine ecosystem is unexplored and understudied. Hence, the present research is focussed on the screening of bioactive compounds from marine actinomycetes isolated from Indian coastal region. This study is designed to determine the … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant and Antimutagenic Activities of Taif Grape (Vitis vinifera) CultivarsAbdelmegid Ibrahim Fahmi, Mohamed Ahmed Nagaty, Ahmed Mohamed El-ShehawiExtract of grape Vitis vinifera has been reported to exhibit antioxidant and antimutagenic activities and the phenolic compounds play a vital role in determining these activities. Therefore; the objective of the present study was to evaluate the antioxidant and anti-mutagenic activities as well as the phenolic composition of different grape cultivar extracts collected from Taif region. The grape cultivars namely; … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 8,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Potential in Lipophilic and Hydrophilic Extracts from Medicinal Herbs (Salvia officinalis and Echinacea angustifolia). A Comparison Between Assays Based on Electron Paramagnetic Resonance and SpectrophotometryFlavia Navari-Izzo, Riccardo Izzo, Mike F. Quartacci et al.Recently, detection of antioxidant activity of plant extracts has caught the attention of researchers. Determination of antioxidant activity is usually performed using stable free radicals. A number of assays is available for screening the antioxidant activity of food constituents, but few of these methods are applicable to lipophilic substances. EPR is the analytical technique that directly measures free radicals making … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 6 Nov 2012 · 9,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractGermination Time Dependence of Bioactive Compounds and Antioxidant Activity in Germinated Rough Rice (Oryza sativa L.)Anuchita Moongngarm, Ekkalak KhomphiphatkulProblem statement: Germinated rice has been recognized as a functional food and its health benefits. However, most related studies were on germinated brown rice but our previous study indicated that germination of rough rice was an effective method to obtain high concentrations of bioactive compounds. Germination time is one of the most important factors affecting the level of biochemical compositions … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Activity of Leaves of Calophyllum rubiginosumMuhammad Taher, Nissad Attoumani, Deny Susanti et al.Problem statement: Calophyllum species have been used in traditional medicine for their therapeutic values for many years. This use was explained by several previous studies where antimicrobial, antifungal, anti-HIV and anti-cancer and antioxidant compounds were isolated from several Calophyllum species. Approach: The leaves were extracted with n-hexane (hexane), dichloromethane (DCM) and methanol using soxhlet apparatus. Total phenolic contents of each … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,630 accessesView PDFCite
