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。

The results showed that the antioxidant capacity of purple sweet potato wine (cooked sweet potato∶water=1∶1.5) was stronger than that of claret under the same alcoholicity (about 11%vol) and the antioxidant activity of purple sweet potato juice was equal to that of purple sweet potato wine before and after the fermentation.

The methods of this study were to use the heat treatments included hot air, hot water and steam to prevent decay. We measured the temperature in 5 mm depth of the surface on sweet potato in heating treatments and also used COMSOL Multiphysics to simulate the process and to predict surface temperature that was undetectable during heating process to insure the effeteness of heat treatments. After heating treatments, sweet potato were stored in cold rooms at 13~15℃ and 85~100%.

To determine the best sampling time of ipomoea lam leaves as well as the value of their resources, dynamic changes in the content of chlorogenic acid from ipomoea lam leaves in different periods and its ability of scavenging free radicals were studied.

摘 要：研究甘薯叶中绿原酸的动态变化规律以及其清除自由基的能力，从而确定甘薯叶最佳采样时期以及甘薯叶的资源价值。

Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus.

甘薯病毒病一直影响着甘薯经济发展，引起甘薯种性退化，导致严重减产(20%~57%)，是影响甘薯生产的重要病害。

Lam. and its related species are called plants of Ipomoea section batatas, which are classified into two groups based on the cross-compatibility with sweetpotato: Group I cross-compatible with sweetpotato and Group II cross-incompatible with sweetpotato.

根据同甘薯的杂交亲和性，将甘薯组植物分为两个群：同甘薯杂交亲和的第Ⅰ群和同甘薯杂交不亲和的第Ⅱ群。

With the isolated and purified PSP as test materials, the chemical model systems were used to produce and OH. resp.
