Abstract

Extracts from Phaseolus vulgaris and Cynara scolymus may reduce food intake and/or postprandial glycemia. This study investigated the effect of standardized extracts of P. vulgaris and C. scolymus and their combination on food intake and glycemia in rats. P. vulgaris and C. scolymus extracts, and their 1:2 combination, were administered acutely to rats (a) given access to regular food and water, (b) given access to regular food, water, and a chocolate-flavored beverage, or (c) infused with a starch bolus. P. vulgaris extract and the combination produced comparable reductions in intake of regular food and chocolate-flavored beverage; conversely, C. scolymus extract was ineffective on both parameters. P. vulgaris and C. scolymus extracts additively contributed to the reducing effect of the combination on glycemic rise. These results suggest that a mixture of P. vulgaris and C. scolymus extracts is preferable over each single extract, as it combines the anorectic effect of the P. vulgaris extract with the hypoglycemic effect of both extracts. These data support the recent clinical use of the combination of P. vulgaris and C. scolymus extracts in the control of appetite, food intake, and postprandial glycemia and represent a successful example of translational research in the nutraceutical field.
