Anti-obesity effects of Foeniculum fructus water extract

초록

We investigated the anti-obesity effects of Foeniculum fructus water extract on body weight, epididymal adipocyte size, plasma lipid levels and activities of key enzymes such as lipoprotein lipase (LPL), acyl-CoA synthetase (ACS) in high fat diet-induced obese mice. Experimental groups were normal diet group (ND), high fat diet group (HFD), high fat diet with 0.05% orlistat group (HFDO), and high fat diet with 0.5% Foeniculum fructus group (HFDF). Eleven-weeks feeding with HFD resulted in significant increase in lipid levels, body weight, liver and epididymal adipose tissue weight, compared with the ND group. Diet containing Foeniculum fructus water extract significantly reduced plasma total cholesterol, triglyceride and glucose concentrations as well as body weight, liver and epididymal adipose tissue weights. Plasma LDL cholesterol levels were significantly lower in the HFDF group than those in HFDO group. LPL activities elevated by a high fat diet were significantly decreased by Foeniculum fructus water extract administration. ACS activities decreased in the high fat diet group and markedly increased in the Foeniculum fructus water extract administered group. All things considered, Foeniculum fructus water extract efficiently inhibits the inflow of fatty acid into the cell, and activates metabolic process that uses fatty acids flowing as an energy source. Thus, Foeniculum fructus water extract may have great potential as a novel anti-obesity agent.
