| 摘 要： | 采用热水浸提和乙醇沉淀的方法提取粗江蓠多糖(gracilaria gigas harvey polysacchrides,GHPS),用苯酚-硫酸法测定糖含量,等离子体原子发射光谱(ICP)测多糖中矿物元素的含量,傅里叶红外光谱仪(FTIR)分析糖类官能团.结果表明:采用热水浸提和乙醇沉淀的方法提取粗江蓠多糖提取率达14.98%,苯酚-硫酸法测得提取物多糖含量为78.2%;ICP测得粗江蓠多糖含Ca,Fe,Mg和S等矿物元素;FTIR分析GHPS有一般糖类物质的特征吸收峰,是一种酸性多糖,同时存在呋喃环和吡喃环.

| Abstract: | Gracilaria Gigas Harvey Polysaccharides(GHPS) were extracted with hot water and sedimentated with ethanol.The amount of polysaccharides was determined by phenol-H_2SO_4 method.The mineral elements and molecular configuration were(analysed) by inductively coupled plasma(ICP) and infrared absorption spectrum(IR).The rate of distillation was 14.98%,the amount of polysaccharides was 78.2%, and GHPS contained manifold mineral elements(Ca,Fe,Mg and S).The IR spectra manifested that the extraction was a compound of polysaccharides,i.e.acidic polysaccharides. |
