Abstract

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