Extraction, characterization and antioxidant activities of polysaccharides from E. corneum gigeriae galli

Characterization, antioxidant and antitumor activities of polysaccharides from purple sweet potato

“…The strong and broad absorption peaks at 3422.0/3421.0/3412.4 cm −1 are attributed to the stretching vibration of O H which indicate hydroxyl groups exist in PSPP1-1, PSPP2-1 and PSPP3-1 (Li & Shah, 2014;Sun et al, 2014c). The absorption peaks at 2920.4/2927.0/2927.7 cm −1 are due to the stretching vibration of C-H in PSPP1-1, PSPP2-1 and PSPP3-1 (Li & Shah, 2014;Xiong et al, 2014). The absorption peaks at 1789-1791 cm −1 in PSPP1-1and PSPP2-1 are due to the stretching vibration of carbonyl group (Zha et al, 2014).…”

“…The EC 50 value of PSPP2-1 is determined to be 1063 g/ml. Although the Fe 2+ chelating capability of PSPP2-1 is lower than that of EDTA (EC 50 = 200 g/ml) (Xiong et al, 2014), its Fe 2+ chelating capability is higher than that of CLP-1 (EC 50 = 3190 g/ml), CLP-2 (EC 50 = 2210 g/ml) and CLP-3 (EC 50 = 2150 g/ml) from Camellia oleifera leaves (Feng et al, 2014).…”

“…The antioxidant properties of polysaccharides are due to their free radical scavenging, metal ion chelating and reducing capacities (Wang et al, 2014b;Xiong et al, 2014). In this study, the DPPH radical scavenging assay, reducing power assay and ferrous ions chelating assay were used to evaluate the antioxidant activities of PSPP1-1, PSPP2-1 and PSPP3-1 (Fig.…”

An economical and efficient technology for the extraction of resveratrol from peanut (Arachis hypogaea) sprouts by multi-stage countercurrent extraction

“…The shapes of the contour plots, circular or elliptical, indicate whether the Fig. 3 (continued) mutual interactions between variables are significant or not (Xiong, Li, et al, 2014;. A circular contour plot indicates that the interaction between related variables is negligible, while an elliptical contour plot indicates that the interaction between related variables is significant (Muralidhar, Chirumamila, Marchant, & Nigam, 2001;Zhang, Li, Xiong, Jiang, & Lai, 2013).…”

Characterization and bioactivities of a novel purified polysaccharide from Endothelium corneum gigeriae Galli

“…EC has strong effects in promoting blood circulation, removing blood stasis, relieving stagnated food, strengthening the spleen and stomach and can be used for the treatment of diarrhea, dyspepsia, infantile malnutrition and mammary gland proliferation [6,7]. In previously study, for the first time, we successfully extracted a newly identified water-soluble polysaccharide (PECG) from EC [8]. On that basis, a novel purified polysaccharide (PECGp) from Endothelium corneum gigeriae Galli was obtained by chromatography of DEAE-52 and Sephadex G-100.…”
