摘　　要：将多糖水解后的单糖转化为糖腈乙酰酯衍生物，用气相色谱分析确定三种茜草多糖由鼠李糖、阿拉伯糖、木糖、甘露糖、葡萄糖和半乳糖组成。茜草多糖ＱＣ－Ⅰ、ＱＣ－Ⅱ和ＱＣ－Ⅲ组成单糖的摩尔比分别为鼠李糖－阿拉伯糖－木糖－甘露糖－葡萄糖－半乳糖＝１．０：０．３２：０．７６：０．６６：１．０４：１．４８；１．０：１．８６：１．２９：０．９９：２．９７：３．０４和１．０：０．５１：０．１３：０．１９：０．３６：１．０４。After the monosaccharides ,hydrolysates of polysaccharide QC-1,CC-Ⅱand QC-Ⅲfrom Rubia Cordifolia L. were inverted into aldononitriles acetylate derivatives , the composi tions of QC-Ⅰ,QC-Ⅱ and QC-Ⅲ were examined by GC.3 kinds of polysaccharide are allcomposed of rhamnose,arabinose,xylose,mannose,glucose and galactose. But the molar ratios of monossacharides,rhamnose:arabinose:xylose:mannose:glucose:galactose were1.0:0.32:0.76:0.66:1.04:1.48,1.0:1.86:1.29:0.99:2.97:3.04 and1.0:0.51:0.13:0.19:0.36 : 1.04 ,respectively.
