Abstract:
Objective To compare the monosaccharide composition and molar ratio of GL-PPT2, GL-PPT3, and GL-PPT4, which are three polysaccharide peptides isolated from the fruit body of Ganoderma lucidum. Methods The polysaccharide peptides were hydrolyzed by triflouroacetic acid, then derivatized by trichloro-aldehyde-1-pheny-3-methyl-5-pyrazolone (PMP), and determined by HPLC method with the 245 nm detection wavelength. Gradient elution with the solution of KH2PO4 (pH 5.0)-acetonitrile (83.5∶16.5) resulted in baseline separation of nine monosaccharides, of which the chromatographic peaks were very clear. Results GL-PPT2, GL-PPT3, and GL-PPT4 comprise the nine monosaccharides of mannose, ribose, rhamnose, glucose, galactose, arabinose, xylose, galactose, and glucuronic acid. Conclusion The ribose in polysaccharide peptides of G. lucidum is first reported.
