Inhibitory Activities of Cudrania tricuspidata Leaves on Pancreatic Lipase In Vitro and Lipolysis In Vivo

الملخص EN

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 IC50 value of 9.91 μg/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.
