The Effects of Saposhnikovia divaricata Aqueous Extracts on the Inflammation and Intestinal Microflora in Allergic Rhinitis Mice

Figure 5

The effects of SD treatment on the intestinal microbial diversity of AR mice ((n) = 5). (a) The statistics of microbial taxa at phylum, class, order, family, genus, and species levels. There was large species abundance at the family and genus level. (b) The relative species abundance histograms on the genus. (c) The boxplots of the alpha diversity index. The Chao1 and observed species indexes are used to analyze the abundance, Shannon and Simpson are used to analyze diversity, the faith’s PD index is used to characterize evolution-based diversity, Pielou’s evenness index is used to characterize evenness, and Good’s coverage index represents coverage. (d) The beta diversity was analyzed by PCoA that was based on the Bray–Curtis, Jaccard, unweighted UniFrac, and weighted UniFrac. All error bars represent the mean ± standard deviation.
