Stilbene glucoside inhibits the glucuronidation of emodin in rats through the down-regulation of UDP-glucuronosyltransferases 1A8: Application to a drug-drug interaction study in Radix Polygoni Multiflori

摘要

Ethnopharmacological relevance: The integrated effects of herbal medicines were the outcome of all of the inherent components. Currently, few studies have focused on the multicomponent interactions in an herbal medicine to elucidate its pharmacological and/or toxicological effects. In this study, an attempt was made to investigate the interaction between stilbene glucosides and the anthraquinones contained in Radix Polygoni Multiflori (RPM) and to explore the interaction's mechanism from the perspective of UDP-glucuronosyltransferase (UGT) regulation.
