From: Cordycepin reduces weight through regulating gut microbiota in high-fat diet-induced obese rats
Diversity and richness of the gut microbiota in rats. (a) Displays the rarefaction curves of samples from the NFD group, HFD group and CCS group. (b) Displays the Shannon index of samples from the NFD group, HFD group and CCS group. (c) PCoA plot. Principal component analysis (PCA) scores plot of gut microbiota based on the relative abundance of OTUs. (d) Cluster analysis, unweighted uniFrac-OTU table. NFD means that the rats were fed a normal diet (n = 3), HFD meansthe rats were fed a high-fat diet (n = 3), and CCS meansthe rats were fed a high-fat diet and received cordycepin (50 mg/kg) (n = 3) for 4 weeks continuously
