Effect of rat intestinal flora on in vitro metabolic transformation of pumiloside / 中国中药杂志

ABSTRACT

To study the metabolic transformation of pumiloside by rat intestinal flora in vitro and identify its metabolites. Pumiloside was incubated in the rat intestinal flora in vitro. HPLC was used to monitor the metabolic process, and HPLC-Q-TOF-MS was used to identify the structures of biotransformation products. In vitro, pumiloside was easily metabolized by rat intestinal flora, and with the prolongation of metabolic time, pumiloside was transformed into several metabolites. Three metabolites were initially identified in this experiment. The study indicated that pumiloside could be extensively metabolized in the rat intestinal flora in vitro.
