Stimulatory Effects of Extracts Prepared from Salix babylonica L. on Fat Catabolism in Mice Fed High-Fat Diet

Abstract

Effects of the ethanol extracts prepared from Salix babylonica L. leaves on the fat deposit induced in mice by feeding a high-fat-diet for 9 wks were studied. Increase in body weight and parametrial adipose tissue weight containing 2,5 or 10g (extract) /kg food was suppressed as compared to that observed in mice fed the high-fat-diet alone. Futhermore, the enthanol extract inhibited the elevation of blood triacylglycerol in rats administered orally a lipid emulsion as compared to that in rats given the emulsion alone. Experiments are now undergoing to isolate other ingredients from the extract and test them for anti-obesity effects.
