          Abstract

          Essential oils obtained by hydrodistillation from the aerial parts of Baccharis gaudichaudiana, B. microcephala, B. penningtonii, B. phyteumoides and B. spicata collected from different locations in Argentina were analyzed. Qualitative and quantitative analysis were performed using a GC/FID/MS system with a special configuration. Essential oil yields ranged from 0.1 to 0.2% (m/v of dry material). Different chemical patterns were observed in the essential oils composition of the species studied: spathulenol and β-pinene were the main constituents in B.gaudichaudiana, whereas caryophyllene oxide and spathulenol were the major constituents in B. microcephala and B. spicata. In this latter species, β-pinene has also been found in high amounts. Germacrene D was the major compound in B. penningtonii. Finally, β-selinene and phytol acetate E were the main components in B. phyteumoides.

          Os óleos essenciais obtidos por hidrodestilação das partes aéreas de Baccharis gaudichaudiana, B. microcephala, B. penningtonii, B. phyteumoidese B. spicata coletadas em diferentes regiões da Argentina foram analisados qualitativa e quantitativamente utilizando um sistema CG e CG/EM com uma configuração especial. Os rendimentos dos óleos variaram de 0,1 a 0,2% (m/v de planta seca). Diferentes compostos foram observados na composição dos óleos essenciais das espécies estudadas: B. gaudichaudiana apresenta espatulenol e β-pineno como constituintes principais e, B. microcephala e B. spicata, espatulenol e óxido de cariofileno em concentrações mais elevadas. Na última espécie citada, o β-pineno também foi encontrado em quantidades significativas. Germacreno D foi o principal componente presente na B. penningtonii. Finalmente, β-selineno e acetato de fitol E foram os principais componentes encontrados na B. phyteumoides.
