Xanthohumol, the major prenylated chalcone found in hops, is known to exert several beneficial effects but only few studies evaluated the safety profile of this natural compound with in part discrepant results. Here, we fed female BALB/c mice with a standard diet supplemented with xanthohumol for 3 weeks, and thus, achieved a daily dose of approximately 1000 mg xanthohumol/kg body weight. There were no significant differences in body weight or food intake between mice on standard diet and animals receiving the same diet supplemented with xanthohumol. Histopathological examination of liver, kidney, colon, lung, heart, spleen and thymus revealed no signs of xanthohumol-toxicity, and biochemical serum analysis confirmed normal organ function. Further, xanthohumol treatment did not affect hepatic glycogen content CYP2E1 and CYP1A2 expression levels, but CYP3A11 mRNA was approximately 30% reduced. Expression of several genes indicative of early hepatic inflammation and fibrosis, a hallmark of chronic liver injury, did not differ between xanthohumol treated and control mice. In summary, these results indicate that oral administration of xanthohumol exhibits no adverse effects on major organ function and homoeostasis in mice. Particularly, hepatotoxic effects could be ruled out confirming a good safety profile of xanthohumol as prerequisite for further studies in humans.
