【摘要】 从我国沿海红藻中提取的粗多糖，经ＤＥＡＥ－纤维素柱层析得到红藻多糖ＲＰ_１，实验证实有明显抗病毒作用。通过气相色谱、红外光谱、Ｙａｐｈｅ测定方法，证明红藻多糖ＲＰ_１含硫酸基是一种硫酸酯化多糖，其单糖组成为半乳糖和３，６－内醚半乳糖，定量分析含量分别为：半乳糖７０．０４％、３，６－内醚半乳糖９．５６％、硫酸基１７．３０％。更多还原

【Abstract】 A rhodophyta polysaccharide （RP₁） was extracted and purified from red alga, Halymemin sinensis Tseng et. C. F.. Its chromatographic behavior and chemical properties suggested that it is a sulfated polysaccharide composed of galactose 70. 44%, sulfonate 17. 30% and 3, 6--anhydrogalactose 9. 56%. Pharmacological screening proved that RP₁ is a virus inhibitor.更多还原
