Flavangenol (pine bark extract) and its major component procyanidin B1 enhance fatty acid oxidation in fat-loaded models.

Flavangenol, one of several pine bark extract products, is expected to prevent metabolic diseases with its potent antioxidant effect, its anti-obesity effect and its improvement of insulin sensitivity. In this study, targeting the liver as one of the organs that plays an important role in energy metabolism, Flavangenol was investigated for its effect on non-alcoholic fatty liver disease (NAFLD), its action mechanism and its active ingredients, using in vivo and in vitro experiment systems. Flavangenol suppressed intrahepatic fat accumulation in Western diet-loaded Tsumura Suzuki Obese Diabetes (TSOD) mice, which develop various metabolic diseases.
