Gas chromatography-mass spectrography was used to analyze the monosaccharide composition of water extracts and alkali-extracted polysaccharides from various Rhodiola Crenulata.The results showed that ST-Ⅰ,ST-Ⅱ and ST-Ⅲ were composed of rhamnose,arabinose,mannose,glucose and galactose with a ratio of 1:2.86:0.43:2.12:0.63,1:2.81:0.28:1.72:0.37,1:3.37:0.58:2.36:0.66 respectively.JT-Ⅰ and JT-Ⅱ were composed of mannose,glucose and galactose with a ratio of 1:0.93:2.90,1:2.01:2.92 respectively.JT-Ⅲ was different from JT-Ⅰ and JT-Ⅱ and contained rhamnose,fucose,arabinose,mannose,glucose and galactose with a ratio of 5.60:1.02:13.20:1:9.27:0.92.
