In this study, a combined application of Polygonatum sibiricum saponin (PSS) with probiotics was developed as a new formulation that could be a candidate for a dietary supplement. The properties of nine probiotics were evaluated by principal component and heatmap analysis. And the hypoglycemic properties of compound probiotics were compared with single strains. The results showed the inhibition (%) of α-amylase was higher when L. casei ATCC393 was used synergistically with L. Bulgaricus 1.1480 compared with single strains as well as other strain combinations. And it was also found that the inhibition (%) of α-amylase was higher as 70.35 % after PSS and the compound probiotic were compounded as a ratio of 2:1. Furturemore, PSS-compound probiotics could regulate the composition of the gut microbiome of T2DM mice and enhance the metabolic capacity. In conclusion, the combination of PSS and compound probiotics has shown massive potential as management nutraceuticals of T2DM.
