Summary:
The application of edible plants with more effective ability to inhibit fat digestion and absorption has recently been explored for possible treatment of hyperlipidaemia. The aim of the present study is to investigate the effect of nine edible plants on the inhibition of pancreatic lipase and pancreatic cholesterol esterase activities, as well as the inhibition of cholesterol micelle formation, and bile acid binding. Our findings have shown strong pancreatic lipase inhibitory activity and the inhibition of cholesterol micellization by mulberry leaf extract. Safflower extract was the most potent inhibitor of pancreatic cholesterol esterase. In addition, cat’s whiskers and safflower extracts had a potent bile acid binding activity. It is suggested that a daily intake of these edible plants may delay postprandial hypertriacylglycerolaemia and hypercholesterolaemia, and therefore may be applied for the prevention and treatment of hyperlipidaemia.
