摘要
目的研究岩藻多糖的提取工艺。方法采用正交优化法,以海带为原料,最佳组合为料液比(1 g:20 mL),温度80℃,提取3次,提取时间10 h。结果岩藻多糖得率25%,经柱层析纯化,纯度达93%。结论此工艺操作简便,成本较低。
Objective To study the extraction technology of fucoidin. Methods With kelp as the material, the optimum extraction conditions with orthogonal optimization method were as follows： solid-liquid ration（1 g：20 mL）, extracting for 3 times at 80 ℃, each for 10 h. Results The yield rate of fucoidin was 25 %. The purity could reach 93% after being refined by colunm chromatography. Conclusion This extraction technology is easily controlled and cost-saving.
