【 摘 要 】

Several studies have suggested that the gut microbiota affect the health of the host. For example, the Firmicutes/Bacteroidetes (F/B) ratio and the proportion of Akkermansia muciniphila in the microbiota have been closely linked to obesity. In this study, we evaluated the effects of an anti-obesity lignan compound, arctigenin (AG), and burdock sprout extract (GSE), which contains AG, on the gut microbiota of an obese mouse model. C57BL/6J mice were fed high-fat, high-sucrose (HFHS) diets containing AG, GSE, or metformin (MF) for 8 weeks. The composition of the gut microbiota and the cecal content of short-chain fatty acids (SCFAs) were determined using 16S rRNA gene sequencing and high-performance liquid chromatography, respectively. Body weight gain was significantly suppressed in mice treated with AG, GSE, and MF. Analysis of the gut microbiota revealed that the F/B ratio was significantly reduced in the AG- and GSE-treated groups. Furthermore, the copy number of A. muciniphila in the feces was significantly increased in obese mice treated with AG and GSE. In addition, the amount of SCFAs (acetic, propionic, and butyric acids) in the cecal content and their fecal excretions were also significantly increased following AG and GSE treatment. Taken together, these results suggest that AG and GSE prevent obesity by improving the composition of the gut microbiota. Moreover, AG promoted the growth of A. muciniphila in vitro. Thus, AG and GSE may function as novel prebiotic supplements to ameliorate obesity, constipation, and intestinal disorders.
