Study on metabolites of scutellarin in gastrointestinal tract by UPLC-MS/MS method / 中国临床药理学与治疗学

ABSTRACT

AIM: The metabolites of scutellarin were studied in gastrointestinal tract.METHODS: Scutellarin was hydrolyzed with hydrochloric acid and ?-glucuronidase.Human intestinal flora and scutellarin were incubated in vitro.The metabolites were identified by UPLC-MS/MS method.RESULTS: Scutellarin could be hydrolyzed with hydrochloric acid and ?-glucuronidase,and could be metabolized by human intestinal bacteria.A main metabolite,scutellarein,also was found in the plasma of healthy volunteers after oral administration.CONCLUSION: There were scutellarin and scutellarein in intestinal before absorption.It was suitable for scutellarin pharmacokinetic studies to determine scutellarein or total aglycone.
