Abstract Abstract: In Brazil, there are two species of Artocarpus that were introduced: Artocarpus altilis (Parkinson) Fosberg, known as fruta-pão, and Artocarpus heterophyllus Lam., known as jaca. Both are used as food and medicine. The objective of this work was to conduct a comparative anatomical and histochemical study between A. altilis and A. heterophyllus. Techniques of optical, polarized and scanning electron coupled to energy dispersive spectroscopy. The anatomical characterization showed the characters of general occurrence in the family Moraceae and of those that allow the differentiation of A. altilis and A. heterophyllus. The histochemistry revealed the sites of synthesis and/or storage of the metabolites. The chemical microanalyses brought new information about the chemical composition of crystals. The study provides pharmacobotanical data for the quality control of the species.
