[Antienzymatic activities of two Leguminosae: bean pods and bean bulls. Antiamylase activity]

Amylase inhibitory activities have been sought in the powders of Phaseolus vulgaris pods and of Vicia faba bean hulls. Unlike to the bean, Phaseolus vulgaris pod has no amylase inhibitory activity and the presence of tannin could not be determined. Contrary, Vicia faba bean hull shows an obvious amylase inhibitory activity. It contains an appreciable content of tannins which may be responsible of this activity. The quantities of amylase whose are inhibited increase in some measure with the quantities of enzyme added. They are not in direct ratio to the quantities of extract, then, inhibition may be of no competitive type.
