Erythroxylum ellipticum

The bark of Erythroxylum ellipticum, a tall Australian tree that reaches a height of 35 feet, contains 0.32% crude alkaloids, from which tropine 3,4,5-trime-thoxycinnamate and tropine benzoate have been isolated (83). These alkaloids are derivatives of tropine (3a-hydroxytropane), thus differing from cocaine-type alkaloids in that the latter are pseudotropine (3)ff-hydroxytropane) derivatives.
