ABSTRACT
This study aimed to elucidate the digestive characteristics of flavonoid components in Xiaoer Chiqiao Qingre Granules(XECQ) in the gastrointestinal environment of infants. An in vitro model was established to simulate the gastric and intestinal environment of infants. UPLC was used to analyze the content change of flavonoid components in XECQ, and their overall content was integrated through the mass fraction weight coefficient method. UPLC-Q-TOF-MS was employed to determine the digestive products of flavonoid components in gastrointestinal fluids and their metabolic pathways. The results showed that in the process of digestion, 11 digestion products were generated by oxidation, reduction, deglycosylation, methylation and other phase â
metabolism. From flavonoid content and component changes, it was found that the flavonoid components in XECQ were relatively stable in the gastric fluid, while their content in the intestinal fluid was first increased and then maintained stable. This was mainly because flavonoid components were released from proteins, polysaccharides and other macromolecular substances during gastrointestinal digestion. In addition, phase â
metabolism occurred, but with relatively low metabolic rate, resulting in their stable content. This study preliminarily explored the digestive characteristics of flavonoid components in XECQ in the infant gastrointestinal environment, which laid a foundation for further studying the absorption, transport and metabolism of pharmacodynamics components in XECQ, and facilitated the study of the biopharmaceutical pro-perties of pediatric Chinese medicine.
