| 摘要: |
| 于1990—1991年，运用13C－NMR和化学分析方法研究中国南方产和移植北方养殖的不同生长发育阶段坛紫菜多糖的组分变化。结果表明，随着藻体生长发育，坛紫菜琼放中3，6-内醚-L-半乳精和6-OCH3-D-半乳精的含量逐渐增加，而硫酸基的含量呈现先增加后减少的规律；北移坛紫菜琼腔中3，6-内醚-L-半乳精的含量高于南方坛紫菜，而硫酸基和6-OCH3-D-半乳糖的含量低于南方坛紫菜。 |

| Abstract: |
| The variation in components of agar polysaccharides from Porphyra haitanensis grown in south China (Zhejiang Province) and transplanted to the north was investigated by chemical analysis and 13C-NMR spectroscopy from 1990 to 1991. The content of 3, 6-anhydro-L-galactopyranose and 6-methoxyl-D-galactopyranose increased with the growth ages, while the content of sulfate increased at first and then decreased. The content of 3, 6-anhydro-L-galactopyranose in the agar polysaccharides from P. haitanensis in the north was higher than that from the south, and the contents of sulfate and 6-methoxyl-D-galactopyranose were lower than those from the south. |
