[Objective] To screen the extraction method of rose polysaccharides,and to provide theoretical foundation for the reuse of residues after extracting the essential oils from rose. [Methods]Rose polysaccharides were extracted by enzyme method. Pre-column derivation HPLC was used to analyze the contents. [Results]The polysaccharides extracted from dry rose and rose residues by normal method were 98. 65 and50. 87 mg /g,respectively. After pretreated by enzyme,the polysaccharides were 124. 87 and 75. 99 mg /g. The monosaccharides in rose polysaccharides were analyzed by pre-column derivation HPLC. And the rose polysaccharides were mainly composed by mannose,rhamnose,galacturonic acid,glucose,galactose and arabinose. And their molar ratio was 1∶ 2. 2∶ 6. 0∶ 2∶ 7. 9∶ 8. 0. The sugar composition of primary structure of rose polysaccharides extracted by enzyme method was the same as that extracted by normal method(not adding enzyme). [Conclusions]Useful rose polysaccharides could be extracted from the residues by enzyme method.
