Composition analysis and antioxidant activity of polysaccharide from Dendrobium denneanum

Purification, composition analysis and antioxidant activity of the polysaccharides from Dendrobium nobile Lindl.

“…In recent years, studies on Dendrobium have attracted more attention due to the potential inhibition and prevention of cancer functions, immunostimulatory and antioxidant activity. Polysaccharides have been isolated from some Dendrobium species (Fan et al, 2009;Hua, Zhang, Fu, Chen, & Chan, 2004;Wang, Zheng, & He, 1988;Zha, Luo, Luo, & Jiang, 2007;Zhao, 1994). However, the polysaccharides from D. nobile have not been investigated.…”

Immune stimulating activity of water-soluble polysaccharide fractions from Dendrobium nobile Lindl.

“…little information was obtained . Most polysaccharides derived from higher plants are relatively nontoxic and do not cause significant side effects, which is a major problem associated with immunomodulatory and antioxidant polysaccharides Fan et al, 2009). Thus, plant polysaccharides are ideal candidates for therapeutics with immunomodulatory and antitumor effects and low toxicity (Schepetkin et al, 2006).…”

Effect of carbon source on production, characterization and bioactivity of exopolysaccharide produced by Phellinus vaninii Ljup

“…Many investigators have attempted to obtain the optimal submerged culture for EPS from several fungi (Tang et al 2008, Xiong et al 2012. It is demonstrated that the yields and compositions of the EPS were affected by culturing conditions, especially when using different carbon sources which might also affect 2034 CHUNPING XU et al the antioxidant property (Fan et al 2009, Xiong et al 2012). However, no data are currently available concerning the effect of carbon sources on the change in chemical characterization and bioactivity of exopolysaccharide of fungal polysaccharides.…”
