Chemical Characterization And Structure Of Exopolysaccharides From Submerged Culture Of New Medicinal Mushroom From China, Phellinus Mori (Higher Basidiomycetes)
INTERNATIONAL JOURNAL OF MEDICINAL MUSHROOMS(2013)
摘要
Two different exopolysaccharides (EPSs) were first time-fractionated from submerged mycelia culture of Phellinus mori (PM) by gel-filtration chromatography: PM-EPS1 and PM-EPS3. Results of compositional analysis using high-performance anion exchange chromatography indicated that both PM-BPS1 and PM-EPS3 were heteropolysaccharides consisting of mannose, glucose, galactose, and rhamnose. Gel permeation chromatography analysis showed that the weight-average molecular mass of PM-BPS1 and PM-EPS3 were 4,990 g/mol and 27,890 g/mol, respectively. Fourier transform infrared spectral analysis of PM-BPS1 and PM-ESP3 revealed prominent characteristic groups corresponding to carbohydrates. H-1 and C-13 nuclear magnetic resonance spectroscopy analysis indicated that PM-EPS3 had a (1 -> 4)-linked mannopyranosyl backbone, with branches of (1 -> 4)-linked glucosyl residues and (1 -> 3, 4)-linked galactopyranosyl residues. Preliminary activity tests in vitro revealed that the hydroxyl radical scavenging activity and total superoxide dismutase activities of PM-EPS3 obviously increased with an increase in concentration at the range 0.1-2.5 mg/mL.
