Research ArticleOpen accessIn the abstractImportance of Soil and Mineral Characteristics in Supporting Sustainable AgricultureIda Suryani, Marliana Sjuaib Palad, Nur Fitriani et al.Soil consists of four main components: Minerals, organic matter, air, and water, which are arranged in the space to form the soil body. Inorganic minerals in the soil come from rock fragments and other primary minerals. Sustainable soil fertility is supported by the nutrient content contained in the minerals. The research objectives were: 1) to observe the physical and chemical … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 25 Mar 2025 · 5,945 accessesView PDFCite
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
