Abstract
Hepatic disorders are a serious health problem threatening human beings. Cuscutae semen (CS), a widely used Chinese medicine, is a tonic to nourish the liver and kidney. Our research aimed to assess the hepatoprotective effect of CS on CCl4 -induced liver injury rats using plasma metabolomics. Liver injury in rats was induced by 40% CCl4 in olive oil twice a week for 21 days. The CS group received 2 g/kg of CS every day for 21 days. The liver tissues were used for histological studies. The serum was used for the analysis of biochemical parameters. Plasma metabolomic analysis was performed using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. CS could relieve hepatocyte necrosis and decrease the levels of serum biochemical parameters in comparison the with CCl4 group. Principal component analysis and orthogonal partial least squares-discriminant analysis on plasma metabolomes showed an obvious separation among the control, model, and CS groups. Heatmap showed that CS-administered mice had similar metabolite profiles as the control group. Seven influential pathways in plasma of the hepatoprotective effect impacted by CS were identified. This study confirmed the hepatoprotective effect of CS, and the related metabolic pathways were discussed.
