Carnosic acid, a new class of lipid absorption inhibitor from sage

The methanolic extract from the leaves of Salvia officinalis L. (sage) showed significant inhibitory effect on serum triglyceride elevation in olive oil-loaded mice (500 and 1000 mg/kg, p.o.) and inhibitory activity (IC50: 94 μg/mL) against pancreatic lipase, which is participated in digestion of lipids. Through bioassay-guided separation using the inhibitory activity against pancreatic lipase activity, 4 abietan-type diterpenes (carnosic acid,...
