ABSTRACT
ObjectiveTo investigate the antidiarrheal effect and mechanism of Zingiberis Rhizoma Recens on diarrhea mice, and to provide research basis for the inhibition of intestinal peristalsis by Zingiberis Rhizoma Recens and its application in the treatment of gastrointestinal diseases. MethodThe diarrhea model of mice was established by Sennae Folium. The control group, model group, Zingiberis Rhizoma Recens low-, medium-, high-dose groups (0.1, 0.32, 1.0 g·kg-1) and loperamide group (1.6 g·kg-1) were set. The intervention effect of Zingiberis Rhizoma Recens with different doses on diarrhea mice was detected by diarrhea score, incidence rate of loose stools (LSIR), grade of average loose stools (ALSG), diarrhea index (DI), intestinal propulsion rate and intestinal pathological section. The serum metabonomics of mice was analyzed by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry (UPLC-QE-Orbitrap-MS), principal component analysisPCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). The conditions were as follows:mobile phase of 0.1% formic acid aqueous solution (A)-0.1% formic acid acetonitrile solution (B) for gradient elution (0-3.5 min, 5%-15%B; 3.5-6 min, 15%-30%B; 6-6.5 min, 30%B; 6.5-12 min, 30%-70%B; 12-12.5 min, 70%B; 12.5-18 min, 70%-100%B), flow rate of 0.4 mL·min-1, injection volume of 5 µL, electrospray ionization (ESI), positive and negative ion detection modes, acquisition range of m/z 100-1 500. ResultCompared with the model group, Zingiberis Rhizoma Recens high-dose group could obviously reduce the diarrhea score, LSIR, ALSG, DI and intestinal propulsion rate (P<0.05, P<0.01), and improve the intestinal mucosal injury. There were 40 main differential metabolites among the control group, model group and Zingiberis Rhizoma Recens high-dose group, including glucose 1-phosphatexanthine, xanthosine and so on. The metabolic pathways mainly included starch and sucrose metabolismamino sugar and nucleotide sugar metabolismfructose and mannose metabolismtryptophan metabolism, and galactose metabolism. ConclusionZingiberis Rhizoma Recens can inhibit intestinal peristalsis in diarrhea mice and exert antidiarrhoea effect, the mechanism of which may be related to the regulation of carbohydrate and amino acid metabolism.
