Abstract:
OBJECTIVE:To study the preventive effect of Lonicera japonica alcohol extract on mice with liver injury based on metabolomics method. METHODS:30 mice were equally randomized into a normal control (isometric normal saline) group,a model(isometric normal saline)group and a group of L. japonica alcohol extract(2 g/kg). The mice were given drugs by ig once a day for 14 consecutive days. On the 8th day of administration,the models were established by giving 0.2% dimethyl sulfoxide (DMN,10 ml/kg)ip once a day for 7 consecutive days. Gas chromatography-mass spectrum(GC-MS)was used to analyze 24 h total ions chromatogram of the urine sample on the 1st,3rd,5th and 7th day of administration of drugs and DMN. The change in endogenic small molecule metabolites in urine was observed. Principal component analysis was employed to explore the change in the metabolite chromatogram and underlying biomarkers in urine. RESULTS:The contour of the chromatogram changed to a largest extent 1 to 5 d after given DMN,but showed an obvious trend towards regression 7 days thereafter. DMN resulted in increase in the contents of 8-phenyl-8-azbicyclo-[4,3,0]non-3-ene-7,9-dione,2-(6-heptynyl)-1,3 dioxolane,bis-(O-methyloxime)-4-ketoglu-cose,and decrease in the contents of malonic acid,2-(4- chlorophenylthiomethoxyl)ethyl,tetrahydro-2-furanacetaldehyde,D-ga-lactose,erythro-pentonic acid and galacturonic acid,in endogenic small molecule metabolites in mouse urine,for which Lonicera japonica alcohol extract can improve that. CONCLUSIONS:Previous administration of L. japonica alcohol extract ig has preven-tive effect to some extent on the physiological and metabolic conditions of mice with liver injury induced by DMN.
