Abstract

The chemicals to which Brazilian angiosperms owe their use in the preparation of arrow poisons, hallucinogens, fish poisons, drugs, stimulants, spices, perfumes and pigments are correlated with the systematic position of the species in which they occur. Most compounds are produced either by the primitive Magnoliidae (sensu Cronquist) or by the advanced Asteridae. The Rosidae-Dilleniidae, precisely the group of subclasses of widest distribution over the country, have heretofore yielded relatively few useful compounds.
