Seasonal Variation in the Yield and the Chemical Composition of Essential Oils from Two Brazilian Native Arbustive Species

A.V.M. Castelo, C.H.S. Del Menezzi and I.S. Resck

Abstract:
This study analysed the influence of seasonality on the production and composition of essential oils from Blepharocalyx salicifolius (Kunth.) O. Berg and Psidium myrsinites DC, which are very common and useful species of the Brazilian Savannah (Cerrado). Steam distillation technique was used to obtain these oils and to investigate their chemical composition, 1H and 13C nuclear magnetic resonance, gas chromatography, mass spectrometry and infrared techniques were employed. The average yields of essential oil were 0.18 and 0.26% from B. salicifolius and P. myrsinites, respectively; both species tended towards higher production in the dry season. Both oil mixtures were composed primarily of monoterpene and sesquiterpene compounds. The monoterpene linalool was found on the essential oil from Psidium species.
