In a comparative analysis of the cardenolides of two Thevetia species, T. ovata Cav. and T thevetioides HBK, the amount of thevetoside in the seeds, and its acetate, was determined, as well as the yield of digitoxigenin obtained from these monoglycosides. T. thevetioides showed a higher concentration of thevetosides (2.81%) than T. ovata (1.06%), which resulted also in a higher yield of digitoxigenin (0.34 and 0.13%, respectively)
