Abstract
From the leaves of Annona squamosa L. a tetrahydroisoquinoline alkaloid has been isolated and identified as the cardiotonic active principle of the drug. The alkaloid has been structurally elucidated as p-hydroxybenzyl -6,7-dihydroxy- 1, 2, 3, 4-tetrahydro-isoquinoline (demethyl-coclaurine = higenamine). Its positive inotropic activity results from an interaction with the ß-adrenoceptors of the heart muscle.
