Abstract
The polysaccharide from purple sweet potato (PPSP) was extracted. The structure was characterized and partial physicochemical properties were described of PPSP via UV, IR, NMR, XRD, DSC-TGA, LDS, and Congo red assay. This study provided a theoretical basis for the in-depth structural analysis of PPSP and the study of its biological activity.
摘要
紫薯多糖（PPSP）被提取出来。通过紫外光谱、红外光谱、核磁共振、X 射线衍射、差示扫描量热-热重分析、激光散射和刚果红试验对 PPSP 的结构进行了表征，并描述了其部分物理化学性质。本研究为深入分析 PPSP 的结构和研究其生物活性提供了理论依据。
