Abstract

The aqueous leaf extract of Moringa oleifera Lam. (LM-A) is reported to have many health beneficial bioactivities and no obvious toxicity, but have mild adverse effects. Little is known about the mechanism of these reported adverse effects. Notably, there has been no report about the influence of LM-A on intestinal microecology. In this study, animal experiments were performed to explore the relationships between metabolic adaptation to an LM-A-supplemented diet and gut microbiota changes. After 8-week feeding with normal chow diet, the body weight of mice entered a stable period, and one of the group received daily doses of 750-mg/kg body weight LM-A by gavage for 4 weeks (assigned as LM); the other group received the vehicle (assigned as NCD). The liver weight to body weight ratio was enhanced, and the ceca were enlarged in the LM group compared with the NCD group. LM-A-supplemented-diet mice elicited a uniform metabolic adaptation, including slightly influenced fasting glucose and blood lipid profiles, significantly reduced liver triglycerides content, enhanced serum lipopolysaccharide level, activated inflammatory responses in the intestine and liver, compromised gut barrier function, and broken intestinal homeostasis. Many metabolic changes in mice were significantly correlated with altered specific gut bacteria. Changes in Firmicutes, Eubacterium rectale/Clostridium coccoides group, Faecalibacterium prausnitzii, Akkermansia muciniphila, segmented filamentous bacteria, Enterococcus spp., and Sutterella spp. may play an important role in the process of host metabolic adaptation to LM-A administration. Our research provides an explanation of the adverse effects of LM-A administration on normal adult individuals in the perspective of microecology.
