PW2 are completely hydrolyzed catalyzed by acid, to have the bond of indicant broken entirely and get the contents of sugar, measured by HPLC. PW2 are mainly made up of D-Glc and D-Gal by 1. 77:1 in molar.

多糖PW2经过完全酸水解后，用高效液相色谱分析结果表明该多糖是由葡萄糖和半乳糖两种单糖组成，摩尔比例为1.77：1。

However, there is a little change in its invert sugar and sucrose content from near ripe to full ripe.

果实愈趋成熟含酸量愈低；而还元糖与蔗糖之含量在荔枝近熟与完熟期间则不大变化。

Moreover,no difference was observed between trace elements added and not added into the medium,which proved that the trace elements contained in Jerusalem artichoke tubers are sufficient for 2,3-BD production.On the basis of the results,separate hydrolysis and fermentation and simultaneous saccharification and fermentation were performed,respectively.

通过摇瓶发酵实验考察了不同底物、不同水解方式以及微量元素对发酵的影响，结果表明，菊芋是良好的发酵生产2，3-丁二醇的底物，采用酸水解或酶水解两种方式制得的糖液发酵效果基本一致，菊芋中含有的微量元素完全能够满足发酵的需要，发酵过程中无需添加微量元素。

In this paper,a high efficient procedure was studied to extract crude sodium alginate, fucoidin and laminarin simultaneously.
