Background : Lentinus edodes are highly utilized as food and medicine, and are known to be suitable for preventing diabetes, high blood pressure and arteriosclerosis. L. edodes were known for prevent obesity metabolisms. Also, present consumers persue the healthy and thin condition. Our research perpose is determined the prevent obesity using L. edodes extracts.
Methods and Results : The effect on adipocyte differentiation and the accumulation of fat in the L. edodes extract on 3T3-L1 cell preadipocyte and cell toxicity were tested. We measurement to evaluate the inhibition effects of L. edodes extracts on the growth of 3T3-L1 cell adipocytes. The tested cells were treated with L. edodes extracts by ethanolic extracts (concetrations at 10, 50, 100 ㎍/㎖) and hot water extracts (temperature at 50℃, 60℃, 70℃, 80℃, 90℃), respectively. Cell toxicity did not affect the growth of cells growth in hot water extracts. Intracellular lipid accumulation was measured by Oil red O method. The inhibitory effect on 3T3-L1 cell by treatment different ethanolic extract concentrations and temperature of hot-waters. The optimal inhibitory conditions of lipid accumulation by ethanoic extracts and hot water extracts were determined the 32.5% ethanol extracts and 33.3% 50℃ hot water extracts.
Conclusion : The results of this study showed that L. edodes extracts had an potentials for reduce lipid accumulation activities. Further more we will examine about the mechanisms of anti obesity activities from L. edodes extracts. This results provides that the basis for antiobesity foods or medicines using Lentinus edodes extracts.
