The compositions and FTIR spectral characteristics of hydrolysis product were studied using GC and FTIR. The results indicated that ASP3 is a kind of pectic polysaccharide which contained the main part of homogalacturonan fragments as "smooth regions" with galacturonic acid and rhaminose, and rhamnogalacturonan segments as "hairy regions" backbone. Galactose, arabinose, mannose and glucose were linked as arabinogalactan, galactan and arabinan, which were the mainly constitution of the branch.

实验结果表明，ASP3是一种果胶多糖，主要由光滑区和毛发区（富含中性糖侧链的鼠李半乳糖醛酸聚糖）两部分组成：GalA和Rha位于多糖分子的主链，由于Rha含量较低，大部分GalA相连形成半乳糖醛酸聚糖光滑区；Gal、Ara、Man及Glc位于多糖分子的支链，其中Gal以较高的聚合度与主链相连，Ara以还原性末端或低聚寡糖的形式与主链相连或与半乳聚糖末端相连形成阿拉伯半乳聚糖。
