Research ArticleOpen accessIn the abstractSeparation, Purification and Anti-aging Activity of Tobacco PolysaccharidesMengyue Huang, Jingwu Song, Shuaishuai Chang et al.To separate tobacco polysaccharides and investigate their antioxidant and anti-aging properties, crude tobacco polysaccharides were extracted from raw tobacco using hot water, followed by purification through DEAE-52 cellulose column chromatography. The molecular weight and monosaccharide composition of the isolated polysaccharides were analyzed using HPGPC and HPLC. The antioxidant activities of these tobacco polysaccharides were tested using DPPH, ABTS, hydroxyl radicals … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 15 Jan 2025 · 5,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractCultivation of Antioxidant-Producing Endophytic Fungus in Rhizophora apiculata Mangrove PlantsAnthoni Agustien, Putra Santoso, Siti Zaharani Zalamah et al.West Sumatra is known as one of the largest areas of mangrove forests in Indonesia, dominated by Rhizophora. Therefore, there will be huge opportunities to discover new types or strains of endophytes and antioxidant compounds, which play an important role in protecting cells caused by free radicals, preventing oxidation, and protecting the human body from ROS. This study aims to … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 4 Aug 2024 · 5,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Activity of Trilobatin and Its Inhibitory Effects on Oxidative Damage of Biological MacromoleculesYuhan Zhai, Yuqing Zhang, Yaping Li et al.Excessive levels of free radicals in the body cause oxidative damage to macromolecules by injuring DNA, proteins, and lipids, which leads to structural and functional defects and ultimately results in a number of illnesses. The antioxidation of trilobatin and its inhibitory activity of trilobatin on oxidative damage of biological macromolecules have not been thoroughly investigated. In this research, the effects … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 28 Oct 2023 · 5,470 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Rose Vinegar Rich in Gamma-Linolenic Acid and Analysis of its Nutritional Composition and Antioxidant ActivityYao Zhang, Qing Liu et al.Despite the rapid development of various types of fruit vinegar or nutrient-fortified vinegar, the weakened functions or high cost is still the main limiting factor for healthy vinegar. In the present study, a new type of rose vinegar was obtained from raw grain supplemented with natural extract of roses through the cooperative fermentation of multiple microorganisms by adding Mucor circinelloides … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 8 Aug 2023 · 6,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractTo Optimize the Brewing Process of Leaf Tea from Hippophae Rhamnoides Linn by the Antioxidant Activity and to Explore its Anticoagulant ActivityYunwen Zhu, Limei Ran, Hongli ZhouToimprove the edible value of Hippophae RhamnoidesLinn. Leaf (HRLL), investigates the optimal brewing conditions and changespeople's brewing habits, and makes better use of resources. The effects ofdifferent parameters (brewing times, brewing time, temperature, andsolid-liquid ratio) on the brewing process of HRLL tea were optimized byresponse surface methodology with antioxidant activity as an indicator.The optimal process was as follows: The brewing … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 14 Nov 2022 · 5,615 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhosphorylation, Characterization, and Antioxidant Activity of Polysaccharides from Flammulina Velutipes ScrapsYingyun Peng, Xue Bai, Hanwen Xu et al.In this study, polysaccharides from Flammulina velutipes Scraps(FVSP) were extracted. The preparation conditions of the Phosphorylated derivativeof FVSP (Ph-FVSP) were optimized based on single experiments and responsesurface analysis. Characterization and antioxidant properties of FVSP andPh-FVSP were investigated. The optimum phosphorylation modification process ofFVSP obtained was as follows: The mass ratio of STPP/STMP was 1:2, the reaction temperature was 70℃, the … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 16 Aug 2022 · 6,015 accessesView PDFCite
