Production and biological functions of low molecular weight fucoidan

岩藻多糖，特别是低分子质量的岩藻多糖具有多种生理活性功能。

Fucoidan , in particular the low molecular weight fucoidan , possess various physiological activities .

结果表明：岩藻多糖硫酸酯可以通过诱导Hela（？）田胞发生凋亡以及自噬性程序性细胞死亡，来抑制细胞的生长。

The result revealed that fucoidan effectively inhibits the growth of Hela cells by inducing autophagy , as well as apoptosis .

形态学研究结果表明，岩藻多糖硫酸酯作用于Hela细胞还可以导致自噬体的形成，这是自噬的一个典型的特征。

In addition , the morphological study indicated a characteristic finding of autophagy , such as the formation of autophagosomes in fucoidan-treated Hela cells .

岩藻多糖经盐酸降解4h后，寡岩藻多糖糖的收率达到75%，超过4h寡糖收率开始下降。

However the percentage of fucoidan oligosaccharide output reachs about 75 % with the hydrolysis by HC1 about 4 hours , and the yield decreases after 4 hours .

研究表明，岩藻多糖的最佳提取温度为100℃，提取时间为6h，加水量为90mL/g，提取率为11.05%；

The result showed that the optimal extracting temperature and time of fucoidin are 100 ? ℃ and 6 ? h , the relative amount of water should be 90 ?
