The root-bark of Erythroxylum hypericifolium contains the new bases tropan-3a-yl 3- hydroxyphenylacetate, ( + ) -tropane- 3a,6p-diol 3- phenylacetate, tropane- 3a,6p-d iol 3 - phenylacetate 6 acetate, tropane- 3a,6fJ,7p-triol 3- p henylacetate, and nortropan - 3-yl p henylacetate; tropan - 3a-yl phenylacetate was also isolated. Chemotaxonomic implications are discussed.
