Examining gut microbiota and metabolites to clarify mechanisms of Dimocarpus longan Lour leaf components against type 2 diabetes

Figure 2 Impact of Dimocarpus longan Lour leaf components on gut microbial diversity in type 2 diabetes mellitus rats. A: Venn diagram; B: Observed-amplicon sequence variant index; C: Chao1 index; D: Shannon index; E: Simpson index; F: Bray Curtis-based principal component analysis; G: Bray Curtis-based nonparametric multidimensional scaling. Results were expressed as mean ± SD (n = 6). All variations were assessed via one-way ANOVA with Tukey-Kramer post hoc analysis; multiple comparisons were adjusted using the Benjamini–Hochberg false discovery rate method. Con: Control group; Mod: The model group; Met: The metformin group; HDLC: The high-dose group; ASV: Amplicon sequence variant.
