Abstract:
Objective: To develop a method for determination of monosaccharide composition of Polygonatum cyrtonema polysaccharides (PCR) by high performance anion-exchange chromatography with pulsed amperometric detection (HPAEC- PAD). Methods: The water-soluble crude polysaccharides were extracted from the P. cyrtonema Hua, then the polysaccharides were hydrolyzed with sulfuric acid, then separated by CarboPac PA1 column (250 mm × 4 mm, 10.0 μm) and with gradient elution, determination of monosaccharide composition in PCP by HPAEC-PAD. Results: The results showed that within the range of 1-100 mg/L it has good linearity (r > 0.999), The detection limitation was 0.015-0.025 mg/L, 1.35%-2.80% RSD, the recovery rates were 88.36%-111.3%. The results showed that the polysaccharides in P. cyrtonema Hua from different regions were composed of rhamnose, arabinose, galactose, glucose, mannose, and fructose. Conclusion: The proposed method has good separation effect and high sensitivity, which can be used for the study on monosaccharide composition and content determination of PCP.
