Edition of Proceedings of the XXVIII International Horticultural Congress on Science and Horticulture for People, Lisbon, Aug. 2010.c2010  aThe family Piperaceae contains nearly 2000 species, most of them distributed in two genera, Piper and Peperomia. In Brazil circa 170 Piper species are found, mainly in tropical areas Their use ranges from flavoring and culinary to raw material for pharmaceutical and cosmetic industry. One of these species, Piper callosum, is used in folk medicine in the Amazon area. The objective of this study was to evaluate the production of biomass (aerial parts) as well as yield and composition of the essential oil from the leaves, according to different spacing between cultivated plants at Embrapa Western Amazon, in Manaus, State of Amazonas, Brazil.  asafrole  aBiomassa  aÓleo Essencial  aPiperaceae  aPlanta Medicinal  aAmazonas  aPiper callosum  aPlantas medicinais1 aBATISTA, A.
