Paotianxiong (PTX) is a processing product of Debx., often used as a tonic food daily. However, the structure and activity of the polysaccharide component that plays a major role still need to be determined. In our work, two new polysaccharides were purified from PTX and named PTXP-1 and PTXP-2. Structural analysis showed that PTXP-1 is a glucan with a molecular weight of 915 Da and a structure of 4)-α-D-Glcp-(1 → as the main chain. PTXP-2 is a glucose arabinoglycan with 4)-α-D-Glcp-(1 → as the main chain, containing 8 glycosidic bonds attached, and a molecular weight of 57.9KDa. In vitro probiotic experiments demonstrated that PTXP-1 could significantly promote probiotic growth and acid production. In vivo experiments demonstrated that both PTXP-1 and PTXP-2 exhibited significant effectiveness in promoting the growth of intestinal probiotics. These findings help expand the application of polysaccharide components extracted from tonic herbs as functional food ingredients.

炮天芎多糖潜在益生元：结构分析和益生元特性


泡天芎（PTX）是Debx.的加工产品，常作为日常滋补食品。然而，起主要作用的多糖成分的结构和活性仍需确定。在我们的工作中，从 PTX 中纯化出两种新的多糖，命名为 PTXP-1 和 PTXP-2。结构分析表明，PTXP-1是一种葡聚糖，分子量为915 Da，结构为4)-α-D-Glcp-(1 → 作为主链。PTXP-2是一种葡萄糖阿拉伯聚糖，具有4)-α -D-Glcp-(1 → 为主链，含有8个糖苷键，分子量为57.9KDa。体外益生菌实验表明PTXP-1能显着促进益生菌生长和产酸。体内实验表明PTXP-1和PTXP-2在促进肠道益生菌生长方面均表现出显着的功效，这些发现有助于扩大从滋补草药中提取的多糖成分作为功能性食品成分的应用。
