This study investigated the protective effects of an aqueous extract of Sonchus arvensisL. (SA) on DSS-induced colitis in mice by adjusting the diversity of gut microbiota. The results showed that SA extract significantly reduced ulcerative disease symptoms, such as body weight loss, diarrhea, bloody stools, disease activity index scores, and pathological changes. Moreover, SA extract also altered the composition of gut microbiota.
Sonchus arvensisL. (SA) is a traditional Chinese food and medicine termed Ju Mai Cai. The aim of this study was to investigate the protective effects of an aqueous extract of SA on dextran sulfate sodium (DSS) -induced colitis in mice by adjusting the diversity of gut microbiota. Male C57BL/6 mice were randomly divided into four groups: CL (control group); ML group (DSS only); SA group (SA extract); and MS group (SA extract + DSS). The protective effect of SA on ulcerative disease was estimated by several analyses (i.e., body weight loss, diarrhea, bloody stools, disease activity index scores, and hematoxylin and eosin staining). The effect of SA on gut microbiota was determined by analysis of the 16S ribosomal RNA gene sequences. The results indicated that MS significantly attenuated the body weight loss. The disease activity index scores were markedly lower in the MS group versus in the ML group. Moreover, the length of the colon was significantly improved in the MS groups versus in the ML group. Pathological changes were markedly improved following the administration of SA to mice with DSS-induced ulcerative disease. The results of Beta diversity analysis revealed that the composition of gut microbiota was significantly different between groups. Taken together, the results indicated that SA extract may prevent ul-cerative colitis.
