Figure 2. Effects of RC and berberine on 16SrRNA gene relative expressions of (a) Bacteroides/total bacteria and (b) Firmicutes/total bacteria in feces of HFD mice.

“Normal”, normal chow diet-fed mice; “HFD”, high-fat diet-fed control mice; “berberine”, berberine-treated HFD mice; “RC”, Rhizoma coptidis-treated HFD mice. Data were expressed as Mean±S.D. (n = 6), *P<0.05, **P<0.01 vs. HFD controls.
