The immunoregulation activity of SPG-1 mainly existed in the part of sugar chain, but keeping its molecular structure intact had some effects on its immunoregulation activity; SPG sulphation had reducing effects on the immunoregulation of SPG-1, whereas, after medium and low acetification of SPG, the immunoregulation of SPG was enhanced. Conversely after high acetification, the immunoregulation of SPG-1 decreased, that is, after introducing sulfuric and acetic acid base in SPG-1, its immunoregulation changed. All of these indicated the structure of SPG-1 was closely connected with its immune activity.⑤.

甘薯糖蛋白SPG-1的免疫调节活性主要在其糖链部分，但保持分子结构的完整性对其免疫调节的活性有一定的作用；甘薯糖蛋白硫酸化对甘薯糖蛋白SPG-1的免疫调节有降低作用，而中、低度乙酰化后，可提高甘薯糖蛋白的免疫调节作用，高度乙酰化后则降低其免疫调节作用，即甘薯糖蛋白引入乙酰基和硫酸基团后，其免疫调节活性发生了改变，这些均表明了甘薯糖蛋白的结构与其免疫调节活性有密切的关系。

In the orthogonal designable experiment ,the analysis results of zirconium source, precipitation , the sulfating agent is 1.54%, 2.27%, 5.11%,respectively. This result show that the influence of sulfating agent to the catalytic activity is the biggest. Under the same density of the sulfuric acid soaks, the effect of sulfuric acid is well compared to ammonium sulfate .The second is the precipitation, but the influence of the zirconia source is the smallest.

正交设计实验中锆源、沉淀剂、硫酸化试剂的极差分析结果分别为1.54%，2.27%，5.11%，此结果说明硫酸化试剂对催化剂的影响最大，其次是沉淀剂，锆源的影响最小，同时表明以Zr(NO3)4·5H2O为锆源、乙胺为沉淀剂、硫酸为硫酸化试剂是催化剂的最佳制备方案。
