Effects of GCBE, its constituents and sesamin on hepatic CPT activity in mice. Mice were allowed free access to a diet containing each sample for 6 days. The CPT activity in the liver mitochondrial fraction was measured by the DTNB method. The columns represent the mean ± SE of 4–5 mice. The asterisks denote a significant difference from the control group, *: p < 0.05 and **: p < 0.01.
