摘要:

油松花粉经热水提取,Sevag 法除蛋白,乙醇沉淀得多糖。采用Sephadex G-100 柱层析对多糖进行初步分离纯化,用红外光谱、紫外- 可见光谱、气相色谱分析对花粉多糖的结构进行初步研究。结果表明:纯化的油松花粉多糖为杂多糖,至少由鼠李糖、阿拉伯糖、木糖、甘露糖、葡萄糖及半乳糖6 种单糖组成。另外,GC图谱显示油松花粉多糖还含有一个未知的单糖,峰面积非常小,含量比较低。UV 检测显示油松花粉多糖在波长260nm 与280nm 处未见有核酸和蛋白特征吸收峰,经IR 检测证实油松花粉多糖具有多糖类物质的特征吸收峰。

Abstract:

A polysaccharide from Chinese pine pollen was obtained through hot water extraction, ethanol precipitation, Sevag deproteinization and Sephadex G-100 chromatography and was analyzed structurally by IR spectroscopy, UV-vis spectroscopy and gas chromatography (GC). The polysaccharide was highly heterogeneous and was mainly composed of rhamnose arabinose, xylose,mannose,glucose and galactose. Besides, GC analysis revealed that the polysaccharide contained an unknown monosaccharide with a small peak area suggesting low content. No characteristic absorption of nucleic acid or protein in the polysaccharide was observed in its UV-vis spectrum and it exhibited characteristic IR absorption of polysaccharide.

Key words: Chinese pine pollen, polysaccharide, speration and purification, structural analysis
