A novel 3alpha,6beta,7beta-triol tropane alkaloid esterified by two benzoyl residues was isolated from the leaves of the endemic cuban species, Erythroxylon alaternifolium. Another novel 3alpha,6alpha,7beta-triol tropane alkaloid esterified by trimethoxycinnamoyl and trimethoxybenzoyl residues was isolated from the leaves and stem bark of a second endemic cuban species, Erythroxylon rotundifolium. Their structures were elucidated as 3alpha,7beta-dibenzoyloxy-6beta-hydroxy-tropane and 3alpha-(3,4,5-trimethoxy-cinnamoyloxy)-7beta- (3,4,5-trimethoxybenzoyloxy)-6alpha,hydroxy-tropane by spectroscopic methods including 2D-NMR techniques.
