Gas-Mediated Intestinal Microbiome Regulation Prompts the Methanol Extract ofto Relieve Colitis.

Abstract

Intestinal dysbiosis plays an important role in the pathogenesis of colitis (UC).can achieve anti-inflammatory effects as a medicine and food homologous vegetable. Luteolin, eriodictyol, fisetin, and kaempferol are the main anti-inflammatory active compounds obtained through mass spectrometry from the methanol extract of(JJSM). JJSM intervention resulted in attenuated weight loss, high disease-activity-index score, colon length shortening and colonic pathological damage in DSS-induced colitis mice. Interestingly, hydrogen sulfide (HS) was inhibited remarkably, which is helpful to elucidate the relationship between active substance and intestinal flora. Furthermore, JJSM administration improved intestinal flora with down-regulating the abundance of harmful bacteria such asandand up-regulating the abundance of beneficial bacteria such asandand enhanced the production of SCFAs. It is worth noticing thatis related to the production of intestinal gas HS. The elevated levels ofand HS will hasten the onset of colitis, which is a crucial risk factor for colitis. The results displayed that JJSM could considerably ameliorate colitis by rebuilding HS-related intestinal flora, which provides a new therapeutic strategy forto be utilized as a functional food and considered as an emerging candidate for intestinal inflammation.
