The composition of Piper vicosanum Yuncker leaf essential oil from the Brazilian Atlantic Forest (Parque Estadual do Rio Doce, Minas Gerais, Brazil) was investigated. GC and GC/MS analysis of the oils from samples of two populations led to the identification of 64 constituents amounting over 93% of the total oil. The composition was dominated by monoterpenoids (56.0-62.6%), with limonene (40.0-45.5%) and 1,8-cineole (10.4-15.0%) as major compounds. This oil is clearly different from those of all other previously reported Piper leaf oils.
