Tropane alkaloids from the bark of Erythroxylum vacciniifolium.
Eight new tropane alkaloids (1-8) were isolated from the bark of "catuaba", a Brazilian endemic plant Erythroxylum vacciniifolium Martius. Their structures were determined by high-resolution mass spectrometry and multidimensional NMR spectroscopy.
