| 中文摘要: |
| 从海湾扇贝中提取分离出糖胺聚糖，分子中除含有氨基己糖和己糖醛酸外，还含有中性糖基。样品经盐酸－甲醇试剂醇解成单糖，用六甲基二硅胺烷和三甲基硅烷硅醚化成三甲基硅醚衍生物，于气相色谱仪中测定，并与标准单糖比较分析，结果发现，扇贝糖胺聚糖含有５种中性糖基，即葡萄糖，半乳糖，木糖，岩藻糖和鼠李糖。 |
| English Summary: |
| The glycosaminoglycan (GAG), isolated from Bay scallop Argopecten
irradians, contains neutral monosaccharides besides hexosamines and hexosuronic acids. The monosaccharides obtained by alcoholysis with HCI-methylalcohol from the sample of GAG was trimethylsilanized with hexamethyldisilan and chlortrimethylsilan (HMDS ' TMCS = 2 : 1). And the trimethylsilyl derivatives of monosaccharides was determined by gas chro-matography. Compared the gas chromatography of the sample with that of standard monosaccharides, it was found that the GAG of the Bay scallop contains five neutral monosaccharides, viz glucose, galactose, xylose, fucose and rhamnose. |
