Optimization of polysaccharides extraction from Gynostemma pentaphyllum Makino using Uniform Design

Antioxidant and immunobiological activity of water-soluble polysaccharide fractions purified from Acanthopanax senticosu

“…In recent years, polysaccharides extracted from plants, animals and microorganisms have attracted increasing attention due to their unique biological activities (Forabosco et al, 2006;Wang, Luo, & Ena, 2007), such as antioxidant activity (Qiao et al, 2009), antitumor activity (Chen, Meng, Liu, Chen, & Zhang, 2010), immunobiological activity (Sun et al, 2008), interferon inducing activity (Kojima, Inaba, Kobayashi, & Kimura, 1996), and anticoagulant (Nagumo & Nishino, 1996). Many studies have shown that polysaccharides can improve the activity of antioxidant enzymes, scavenge free radicals, and inhibit lipid oxidation (Xu et al, 2009a).…”

A comparison study on microwave-assisted extraction of Artemisia sphaerocephala polysaccharides with conventional method: Molecule structure and antioxidant activities evaluation

“…Many papers aimed at investigating the influence of extraction parameters, such as particle size, ratio of solvent to raw material, extraction time, extraction temperature, pH value and number of extraction [1][2][3][4][5]. Initially classical hot water extraction (HWE) of polysaccharides has been carried out just to compare with microwave-assisted extraction (MAE).…”

Effects of Polysaccharide Elicitors from Endophytic Fusarium oxysporium Dzf17 on Growth and Diosgenin Production in Cell Suspension Culture of Dioscorea zingiberensis

“…Polysaccharide mixture with molecular weight greater than 8,000–14,000 Da was kept in dialysis tube. The carbohydrate content of EPS was measured spectrophotometerically by the method of anthrone-sulfuric acid [34], which involved sulfuric acid hydrolysis of the sample in the presence of anthrone agent at 100 °C. The absorbance at 620 nm was measured and calibrated to carbohydrate content using glucose as a reference.…”
