摘要
为选择一种准确快捷的方法测定银耳多糖的单糖组成,对薄层色谱法(TLC)、气相色谱法(GC)、高效液相色谱法(HPLC)三种色谱方法进行比较。结果表明,前两种方法的测定结果均不理想,而HPLC法,操作简便,灵敏度高,分离效果好,信息完整。测定结果为由葡萄糖、甘露糖、葡萄糖醛酸、木糖、岩藻糖组成,其摩尔比为0.24∶1.00∶0.06∶0.29∶0.25。HPLC法对酸性杂多糖组成糖分析是一种比较理想的选择。
To find an accurate and fast method to determine the monosaccharide composition of Tremella polysaccharide, thin layer chromatography （ TLC）, gas chromatography （GC） and high performance liquid chromatography （HPLC） were compared. The results of TLC and GC were not ideal. However, HPLC was a simple method with high sensitivity, good resolution and integrity information. The result of HPLC analysis showed that the monosaccharide compositions were Glc,Man,GlcA,Xyl and Fuc,with the mole percentage of 0.24： 1.00： 0.06： 0.29： 0.25. Consequently, HPLC is the most suitable method for mon^saccharide composition analysis.
