Obesity is an important risk factor that significantly increases mortality and disease rates in the cardiovascular disease, diabetes, and various diseases. So far, the most powerful way to inhibit fat absorption is pancreatic lipase inhibitors. In this study, we investigated the anti-obesity effect of the extract of Juniperus rigida. Juniperus rigida extract (JRE) had a inhibitory effect on pancreatic lipase activity (=8.63 /ml). In in vivo oil-emulsion loading test, this extract also inhibited the intestinal fat absorption. In addition, we measured inhibitory effects of JRE on activity of phosphodiesterase (PDE) and hormone sensitive lipase (HSL) among the important enzymes associated with lipolysis. JRE strongly inhibited PDE activity (=4.56 /ml), whereas inhibitory effect on HSL activity was very weak compared with orlistat. As a result, JRE inhibited the absorption of fat by inhibiting the activity of pancreatic lipase and induced lipolysis through inhibition of PDE activity. Therefore, we suggest that Juniperus rigida may be a potential therapeutic agent improving obesity.
