To identify effective herb to treat obesity, we screened 115 herbal extracts for inhibition of porcine pancreatic lipase (triacylg-ycerol acylhydrolase, EC 3.1.1.3) activity in vitro. Of the extracts tested, Cudrania tricuspidata leaves exhibited the most pronounced inhibitory effect on lipase activity with an IC(50) value of 9.91 mug/mL. Antilipid absorption effects of C. tricuspidata leaves were examined in rats after oral administration of lipid emulsions containing 50 or 250 mg C. tricuspidata/kg body weight. Plasma triacylglycerol levels 2 h after the oral administration of emulsions containing C. tricuspidata were significantly reduced compared to the untreated group (P < 0.05). These results suggest that C. tricuspidata leaves may be useful for the treatment of obesity.
