Resumo
Lychnophora ericoides Mart., commonly known as arnica, is typical of campos rupestres and
belongs to the family Asteraceae. In the farmacotherapeutic aspect it is used as anti-inflammatory and
anesthetic among other applications. Aiming at defining the best period to collect the plant, it was necessary
to trace the seasonal profile of the essential oil content, not identified so far. For that, preserved
areas in Cristalina and Vianópolis, two cities located in the state of Goiás, in the Midwestern Region of
Brazil were chosen. The plants were collected from July 2001 to July 2002. Samples of each area were
submitted to extraction by hydrodistillation and 71 components were found in the essential oil of this
plant. The samples of essential oil extracted were analyzed by gas chromatography-mass spectrometry
(GC-MS). The plants collected in Cristalina presented higher amount of oil compared to the ones from
Vianópolis, showing the highest percentages in September 2001 and November 2001. No significant
difference was observed in oil content of the plants collected in Vianópolis.
