南柴胡多糖分离与组成的初步研究

Studies on the Composition of Polysaccharide from Bupleurum scorzonerifolium

南柴胡粗多糖经糖腈乙酰酯化后采用高分辨毛细管气相色谱分析 ,发现南柴胡粗多糖主要由 L -阿拉伯糖、核糖、D-木糖、D-甘露糖、D-葡萄糖、D-半乳糖等单糖组成 ,校正因子法测得它们的摩尔比为 0 .10 6∶ 2 .6 5 2∶4.0 70∶ 0 .5 19∶ 0 .930∶ 2 .5

Composition of the polysaccharide from Bupleurum scorzonerifolium Willd was studied by high resolution capillary gas chromatography after hydrolysis and followed by acetylation and esterification of the hydrolysate The results showed that it is composed of arabinose, ribose, D xylose, D mannose, D glucose and D galactose, with a molar ratio of 0 106∶2 652∶4 070∶0 519∶0 930∶2 518.
