• Monosaccharide composition

A simple, rapid and sensitive analytical method for the determination of monosaccharide composition in Cyclocarya paliurus polysaccharide was developed and validated. This method was based on hydrolysis of the polysaccharides followed by high-performance anion-exchange chromatography analysis. The effects of sodium hydroxide concentration and column temperature on retention and separation of the monosaccharide were investigated with Carbo PAC (TM) PA10 analytical column. The established method was validated and the results showed that this method had good linearity (R-2,0.9987-0.9999), adequate accuracy (98.53-102.13% recovery), high precision (relative standard deviation <3.8%) and sensitive detection limits (2.57-7.86 nM), with a simple preparation of the samples (no need to derivatize the samples) and short run time (20 min). The results showed that the C paliurus polysaccharide consisted of rhamnose, arabinose, galactose, glucose, mannose and xylose in the molar ratio of 1.00:1.85:3.26:3.12:0.85:0.29.
