Study on metabolites derived from Zhideke granules in rats in vivo
To analyze the metabolites of Zhideke granules and speculate its metabolic pathway in rats
in vivo
.
METHODS
2
Male SD rats were randomly divided into blank group and administration group (Zhideke granules, 9.45 g/kg); they were given ultrapure water or relevant medicine, twice a day, every 6-8 h, for 3 consecutive days. Serum, urine and feces samples of rats were collected, and their metabolites were identified by UPLC-Q-Exactive-MS technique after intragastric administration of Zhideke granules; their metabolic pathways were speculated.
RESULTS
2
After intragastric administration of Zhideke granules, 16 prototype components (i.g. irisflorentin, baicalin, chlorogenic acid) and 11 metabolites (i.g. hydration products of kaempferol or luteolin, methylation products of chlorogenic acid, and hydroxylation products of baicalin) were identified in serum, urine and feces of rats. Among them, 8 prototype components and 4 metabolites were identified in serum samples; 10 prototype components and 7 metabolites were identified in urine samples; 8 prototype components and 5 metabolites were identified in the fecal samples.
CONCLUSIONS
2
The metabolites of Zhideke granules in rats mainly include baicalin, irisflorentin, chlorogenic acid, and the main metabolic pathways included methylation, hydroxylation, glucuronidation.
