Metabolomics study of dried ginger extract on serum and urine in blood stasis rats based on UPLC‐Q‐TOF/MS

Blood stasis syndrome (BSS) is the pathological basis of many cardiovascular diseases. Ginger is often used as herbal medicine, condiment, and health food in China and Southeast Asia to improve some symptoms of cardiovascular disease, but its mechanism of efficacy and metabolic processes is not clear enough. In this study, a rat model of BSS was successfully established and treated with different doses of dried ginger extract. After the end of the administration period, the blood and urine of 5 groups of rats were collected for metabonomic analysis. Multivariate statistical analysis was used to explore metabolites and metabolic pathways, and the correlation between metabolites and pharmacodynamic indicators was further explored. The experimental results show that the pharmacodynamic indicators of dried ginger group (DG) extracts of different doses have different degrees of changes than model group (MG), and the high dose of dried ginger group (GJH) changes is the most significant (p < .05 or p < .01). Besides, 22 different metabolites were identified in the experiment. These metabolites mainly involve seven metabolism pathways in different impact value. DG has therapeutic effects on BSS rats by regulating multiple metabolic pathways. This study provides an effective method for understanding the metabolic mechanism of DG extracts on BSS.
