Abstract

Sarmentoside-A extracted from the seeds of Strophanthus sarmentosus was tested on rabbit heart preparation. Its cardio active property compared favourably with digoxin. Both drugs (Sarmetoside-A and digoxin) increased the force and rate heart contractions; these effects were antagonized by potassium chloride solution.
