Abstract

is a Chinese herbal medicine with various bioactivities. Three fractions (GUPS-I, GUPS-II and GUPS-III) of polysaccharides (GUPS) were obtained with molecular weights of 1.06, 29.1, and 14.9 kDa, respectively. The monosaccharide compositions of GUPS-II and GUPS-III were similar, while that of GUPS-I was distinctively different. The results of scanning electron microscopy, FT-IR, and NMR suggested that GUPS-II and GUPS-III were flaky with a smooth surface and contained α- and β-glycosidic linkages, while GUPS-I was granulated and contained only α-glycosidic linkages. Moreover, GUPS-II and GUPS-III exhibited better bioactivities on the maturation and cytokine production of dendritic cells (DCs) in vitro than that of GUPS-I. An in vivo experiment showed that only GUPS-II significantly enhanced the maturation of DCs. These results indicate that GUPS-II has the potential to be used in combination with cancer immunotherapy to enhance the therapeutic effect.

摘要

是一种具有多种生物活性的中草药。获得了多糖（GUPS）的三个级分（GUPS-I、GUPS-II和GUPS-III），分子量分别为1.06、29.1和14.9 kDa。GUPS-II和GUPS-III的单糖组成相似，而GUPS-I的单糖组成明显不同。扫描电子显微镜、傅里叶变换红外光谱和核磁共振的结果表明，GUPS-II和GUPS-III呈片状，表面光滑，含有α-和β-糖苷键，而GUPS-I呈颗粒状，仅含有α-糖苷键。此外，在体外，GUPS-II和GUPS-III对树突状细胞（DCs）的成熟和细胞因子产生表现出比GUPS-I更好的生物活性。体内实验表明，只有GUPS-II显著增强了DCs的成熟。这些结果表明，GUPS-II有潜力与癌症免疫疗法联合使用以提高治疗效果。
