Fifteen alkaloids were characterized from the leaves of Erythroxylum hypericifolium; the majority are esters of cinnamic acid and benzoic acids. 3α-cinnamoyloxytropan-6-β-ol is the main base.New alkaloids reported are 3β-cinnamoyloxytropane, 3α,6β-dicinnamoyloxytropane,3-cinnamoyloxynortropan-6-ol, 6β-acetoxy-3α-cinnamoyloxytropane and, tentatively, 6-phenylacetoxytropan-3-ol.Two mixed cinnamate dimers were also found.Some syntheses are reported and the chemotaxonomic implications of the results are discussed. Key Word Index Erythroxylum hypericifolium; Erythroxylaceae; leaves; tropane alkaloids; cinnamate dimers; tropane alkaloid synthesis; chemotaxonomy.
