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 · 5,103 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrasound-Assisted Enzymatic Extraction of Polysaccharides from Waste Corn Bract: Process Optimization, Characterization, Antioxidant and Anti-Diabetic PotentialsYihui Liu, Yayi Li, Na Niu et al.Corn bract is the main agricultural waste of corn production and processing. Little information is focused on its value-added utilization. In the present study, the Ultrasound-Assisted Enzymatic Extraction (UAEE) was used for the first time to extract Corn Bract Polysaccharides (CBPs). The optimum conditions of UAEE for CBPs extraction were: Cellulase amount of 0.7%, enzymolysis for 58 min, and ultrasound … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 28 Jun 2022 · 6,126 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Deproteinization, Antioxidant Acticities and Inhibitory Effect on α-Amylase of Polysaccharides from Corn SilkYaping Li, Songbiao Shi, Xiudong Yang, Hongli ZhouAn approach of deproteinization of polysaccharides from corn silk (CSPs) was established to improve the purity and activities of CSPs by investigating Sevag method, trichloroacetic acid (TCA) method and HCl method. Deproteinization rate, polysaccharide retention rate, antioxidant activities and inhibition α-amylase effects were used as indicative mark to select suitable deproteinization method of CSPs.
