Gut microbiota diversity analysis of mice feces. (a) α-Diversity of bacteria communities measured by the Shannon index (A) and the Simpson index (B); (b) the principal coordinate analysis (PCoA) plot visualizing the data based on Bray–Curtis dissimilarities. A, normal group with middle-dose aqueous Cistanche tubulosa (CT) extract added; B, normal group; C, model group; D, model group with high-dose CT aqueous extract added; E, model group with middle-dose CT aqueous extract added; F, model group with low-dose CT aqueous extract added.
