CYP mRNA expression in liver in ovariectomized mice. Values are expressed as mean ± SEM, n = 8; means with different letters differ, p < 0.05. The data were analyzed using one-way ANOVA, and differences among the groups were assessed by Tukey’s post hoc test. Sham-operated mice fed a control diet (Sham), ovariectomized mice fed a control diet (OVX), OVX mice fed a 0.39% licorice oil extract-supplemented diet (OVX+10 L), and OVX mice fed a 1.95% licorice oil extract-supplemented diet (OVX + 50 L).
