Abstract

The physiological effects of the Stevia-derived compounds, rebaudioside A, stevioside and steviol have been the focus of several studies due to their use as sweeteners in food. Despite that, little is known about their potential food-drug interactions. In the present study, IPEC-J2 cells and primary hepatocytes were used to investigate the effect of rebaudioside A, stevioside and steviol on cytochrome p450 (CYP) mRNA expression. Moreover, hepatic microsomes were used to investigate direct interactions between the compounds and specific CYP activity. In IPEC-J2 no changes in mRNA expression of CYP1A1 or CYP3A29 were observed with the Stevia-derived compounds. In primary hepatocytes all three tested compounds induced a significant increase in CYP3A29 expression. The tested compounds had no direct effect on specific CYP activity. In conclusion, rebaudioside A, stevioside and steviol induce only minor or no changes to the CYP expression and activity, and are not likely to cause food-drug interactions.
