Research ArticleOpen accessIn the abstractEvaluation of Antioxidant and Antibacterial Activities of the Polysaccharides from Mycelium and the Culture Medium of Pleurotus Eryngii Strain UN-1Qing Liu, Haodong Wu, Ying Wu et al.Pleurotus eryngii was one of the most precious and ordinary edible mushrooms, and its polysaccharides were the major active substances. In this study, P. eryngii strain UN-1 was cultured in a liquid medium at 25℃ under a shaking of 80 rpm for 7 days. Two crude polysaccharides named CPN and CPNM were obtained from the mycelium of P. eryngii UN-1 … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 19 Jul 2022 · 6,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractCell Longevity of Yeast Saccharomyces cerevisiae by Clove Bud Extract Treatment May Occur in Sirtuin-Independent PathwayZahrah Qolbaina Ariybah, Rika Indri Astuti, Sri ListiyowatiAccumulation of free radicals causes cell damage that leads to a phenomenon called aging. Antioxidant application is one potential strategy to avoid the damage of free radical accumulation. Many reports resume that clove, one of Indonesia’s spices, contain high amount of antioxidant. Our previous research had proven that clove extract could extend longevity in yeast Saccharomyces cerevisiae. However, cellular mechanism … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 3 Aug 2021 · 6,659 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 abstractOptimization of Chelating Process of Polysaccharides of Lyophyllum decastes with Zinc and Its Antioxidant ActivityBing Xu, Yi Dai, Jing Hong, Yiyong ChenIn this study, polysaccharides of Lyophyllum decastes (LDS) were used as raw material. The chelating rate was set as the index, the effect of chelating time, mass ratio and initial mass concentration on chelating rate was investigated. Response surface method was used to optimize the preparation technology of LDS and Zinc (Ⅱ) chelate (LDS-Zn) based on single factor experiments. LDS-Zn … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 26 Aug 2020 · 11,761 accessesView PDFCite
Review ArticleOpen accessIn the abstractBioactive Functional Foods for Cardiovascular DiseasesKiren Mustafa, Iqra Ajmal, Tahira Naz et al.Cardiovascular Disease (CVD) is a chronic pathological disorder regarded as a serious health concern round the globe. It is a multifactorial disease, with a range of various causative agents, among that dietary factor is considered the most important and may to a large degree determine CVD risk. Unfortunately, it has been less widely investigated. This review outlines the general aspects … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 17 Aug 2020 · 7,831 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 abstractOptimization for the Extraction of Polysaccharide from Walnut (Juglans regia L.) Leaves: Antioxidant Activities in VitroShuqing Yang, Haifang Xiao, Shuyan Yu et al.Cellulase-assisted extraction of Walnut Leaf Polysaccharide (WLP) was studied. Single factor test and response surface design were employed to optimize the technological conditions. The consequences indicated that the highest WLP yield of 5.21% was achieved with raw material ratio of 50 mL/g, cellulase dose of 41488.52 U/g, enzymolysis pH of 5.88, enzymolysis time of 29.74 min and enzymolysis temperature of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 23 Oct 2019 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractModulation of Aging in Yeast Saccharomyces cerevisiae by Roselle Petal Extract (Hibiscus sabdariffa L.)Sarima, Rika Indri Astuti, Anja MeryandiniCellular aging drives diseases. Free radicals are called the main cause of cellular aging. Antioxidants can protect the body from free radical attack by reducing its negative effects. An antioxidant source can be obtained from plants, such as roselle (Hibiscus sabdariffa. L). This research was conducted to analyze the ability of roselle petals extract to increase the life span of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 1 · 6 Apr 2019 · 9,646 accessesView PDFCite
