Research ArticleOpen accessEvery word in the titleEffect of Ultra-High-Pressure Treatment on the Chemical Composition and Aroma of Flue-Cured Tobacco Leaves for Heated Tobacco ProductsXinbo Lu, Jie Yin, Ying Yuan et al.The influences of different Ultra-High-Pressure (UHP) treatments on the chemical composition and the low-temperature pyrolysis products of Flue Cured Tobacco Leaves (FCTL) that applied in heated tobacco products were investigated in this study. Results indicated that UHP treatment reduced total alkaloids content significantly (p<0.05), especially 500-600 MPa treatment group (2.34±0.00%, 2.34±0.01%). Increase in sugars and potassium content were observed after … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 19 Oct 2025 · 2,154 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeparation, 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 accessEvery word in the titleDiversity of the Rhizosphere Soil Culture-Dependent Fungi of Mature TobaccoXiaolin Li, Xinzhu Li, Kewei Zhao et al.Problem statement: The maturation of tobacco is a very important period of tobacco production. Until recently, there are no many reports on tobacco rhizospheric culturable fungi, especially at the mature stage. Approach: Five rhizosphere soils of tobacco and five non-rhizosphere soils of tobacco were collected in Yanbian county, Panzhihua. Sixty-one fungal strains isolated from these soil samples were analyzed by … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 9,881 accessesView PDFCite

M. Eltayeb, Guo-An Zhang, Jiu-Gao Xie, Feng-Yu MiProblem statement: The toxicity of seven of Allylisothiocyanate (AITC) formulations, AITC pure and in mixture with cypermethrin and chlorpyrifos, was evaluated using spray application and fumigation method against the diamondback moth, Plutella xylostella (L.), the small cabbage white butterfly, Pieris rapae (L.) and the tobacco cut worm, Spodoptera litura Fabr. Approach: Response varied according to insect species, specific formulation and … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 6,993 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConcentration and Physicochemical Properties of Chitosan Derivatives Determine the Induction of Defense Responses in Roots and Leaves of Tobacco (Nicotiana tabacum) PlantsAlejandro B. Falcón-Rodríguez, Juan C. Cabrera, Eduardo Ortega, Miguel Ángel Martínez-TéllezProblem statement: The chitosan derivatives promote diverse defensive responses in plants, which are affected by chitosan chemical features and concentration. Glucanase (EC 3.2.1.6), Phenylalanine Ammonia-Lyase (PAL, EC 4.3.1.5) and peroxidase (POD, EC 1.11.1.6) are key enzymes in tobacco defense responses. Thus, the aim of this study was to know the behavior of their enzymatic activity in leaves and roots of … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,270 accessesView PDFCite
