岩藻聚糖硫酸酯 提取于海帶科植物海帶（Laminaria japonica ）

Properties

(characteristics):

性狀﹕

微黄色粉末，能溶于水

藥理﹕

1. anti-tumor: fucoidans inhibit the heparinase of cancer cells and  inhibits secretion of growth factors of cancer cells. These growth factors are attached to the sulfated heparin. Fucoidans also have strong attraction to some of those growth factors and prevent them to return to the combining to the cancer cells. The cancer cells that have combined with fucoidans become mal-nourished and  the reproduction function of the cancer cells will become weakened and exhausted.
2. anti-virus.
3. antibiotic
4. anti platelet coagulation: anti blood clot
5. lower blood lipids
6. suppresses overly active auto immune system [1]

藥理﹕

1. 抗凝作用，
2. 促進腎臟損傷的修復作用，
3. 抗氧化、
4. 抗血脂、
5. 抗凝血、
6. 岩藻聚糖硫酸酯 的抗癌作用：
   抑制癌细胞所分泌的肝素酶，使得附着硫酸類肝素的癌细胞增殖因子难以游离出来；另外，岩藻聚糖硫酸酯 對一部分的增殖因子有很强的吸附作用，所以可將從硫酸類肝素上游離出 來的增殖因子吸附，避免其回復結合到癌细胞。和岩藻聚糖硫酸酯 結合後的癌细胞由於無法獲取增殖因子，漸漸發生 營養不足、增殖能力减弱、逐漸趋向衰竭，其結果使得癌细胞向周围組織的浸潤受到抑制而 抗 腫瘤、
7. 抑制免疫作用
