A glycoside and African arrow poison from ouabaio, obtained from the wood of Acocanthera ouabaio or from the seeds of Strophanthus gratus; its action is qualitatively identical to that of strophanthus and the digitalis glycosides; used for rapid digitalization; often used in pharmacological studies because of water solubility.
