| 摘 要： | 分别采用碱处理水提法和KCl分级提取蜈蚣藻多糖,研究不同提取方法对蜈蚣藻多糖中3,6-内醚半乳糖、D-半乳糖、硫酸根及其总糖含量的影响。结果表明:粗多糖KCl分级为不溶胶多糖和可溶胶多糖,不溶胶多糖占0.68%,可溶胶多糖占86.25%;不溶胶多糖中硫酸根含量、总糖含量、3,6-内醚半乳糖含量和D-半乳糖含量分别为17.94%、21.27%、29.97%和20.65%,可溶胶多糖中硫酸根含量、总糖含量、3,6-内醚半乳糖含量和D-半乳糖含量分别为29.24%、53.76%、53.70%和32.78%。碱处理后多糖中硫酸根含量降低,3,6-内醚半乳糖含量增加,总糖含量无显著变化。体外细胞毒性测试结果表明,蜈蚣藻多糖对癌细胞株ECA-109具有较强的抑制作用。

| Abstract: | The polysaccharides were extracted from Grateloupia filicina with hot water extraction,alkali extraction and the KCl classification extraction,and the properties were also studied,including the contents of the sulfate radical,the total sugar,3,6-anhydro galactose,and D-galactose in the samples.The results indicated that the Grateloupia filicina polysaccharides could be fractionated to two kinds of polysaccharides,the KCl-insoluble section and the KCl-soluble section.The contents of the KCl-insoluble polysac... |
