摘要: 采用热水提取法从大叶金花草中提取大叶金花草多糖,用酶法和Seveg法去除蛋白质,H2O2脱色,经DEAE-纤维素(Cl-)柱层析纯化后,纸层析和Sephadex G-100 凝胶柱层析证实为单一组分,并用凝胶色谱法、薄层层析、乙酰化GC-MS、紫外光谱和红外光谱等对其组成和结构进行了研究。大叶金花草多糖平均分子质量为8.6×104u,由阿拉伯糖、葡萄糖和糖醛酸组成,在260和280nm处有多糖无核酸和蛋白质的吸收峰。大叶金花草多糖是含有β-吡喃葡萄糖的非蛋白类单一多糖。

Abstract: Water-soluble polysaccharide in Stenoloma chusanum(Linn.)Ching is extracted by means of hot water. Polysaccharide is purified by enzyme treatment and Seveg method to remove protein, then decolorized by 10% H2O2 to remove pigment, followed by DEAE-cellulose column chromatography. Polysaccharide is shown to be a single homogeneous component by PC and Sephadex G-100 column chromatography, and their structural composition was studied by means of permeation chromatography (GPC),TLC, GC-MS, UV, IR, etc.. The average molecular mass of polysaccharide is 8.6×104u. Polysaccharide is composed of glucose, arabinose and uronic acid. There is no absorption peak of protein and nucleic acid at 280 and 260nm. Polysaccharide of this plant is a non-proteinous single polysaccharide containing β-glucopyranose.
