Abstract

The present review focus in quinones found in species of Brazilian northeastern Capraria biflora, Lippia sidoides, Lippia microphylla and Tabebuia serratifolia. The review cover ethnopharmacological aspects including photography of species, chemical structure feature, NMR datea and biological properties. Chemical transformations of lapachol to form enamine derivatives and biological activities are discussed.

Acknowledgments

The authors would like to acknowledge Brazilian agencies CAPES, CNPq, FAPERJ PRONEX for financial support and to Dr Victor M. Rumjanek (DEQUIM-UFRRJ) for English revision.
