RESUMO: 

Os óleos essenciais encontram ampla aplicação industrial, empregando-se puros, na forma
de substâncias isoladas ou a parte vegetal que os contém. Este trabalho teve como objetivo estudar a
produção de óleo essencial em função da época de colheita (primavera, verão, outono e inverno) da 
matéria-prima vegetal (folhas e galhos), visando o controle de qualidade no manejo de populações naturais de
catuaba (Trichilia catigua A. Juss.) e negramina (Siparuna guianensis Aubl.). Na análise dos dados 
considerouse o esquema de parcelas subdivididas, tendo nas parcelas as épocas (estações do ano) e nas subparcelas
as partes vegetais, no delineamento em blocos casualizados com 6 repetições. A extração de óleo essencial
(OE) foi expresso com base no peso seco e extraído por arraste a vapor. Os resultados mostraram que a
catuaba e a negramina não apresentaram variabilidade sazonal na produção de óleo essencial; observouse 
também, que não existe interação entre épocas e partes vegetais para ambas espécies. Contudo,
visando otimizar as operações de manejo em função das estações do ano e os maiores rendimentos de
óleo essencial, a colheita de catuaba deve ser realizada na estação do inverno ( 0,21% OE folhas e 0,16%
OE galhos) e de negramina na estação do outono (0,18% OE folhas e 0,065% OE galhos).

ABSTRACT: 

Production of essential oil in catuaba (Trichilia catigua A. Juss) and negramina (Siparuna
guianensis Aubl.) in function of the harvest time. The essential oils find a wide industrial application, being
used pure, in the form of isolated substances or the vegetable part that contains them. This work had as
objective to study the production of essential oil in function of the harvest time (spring, summer, autumn and
winter) of the vegetable raw material (leaves and branches), seeking the quality control in the management
of natural populations of these species. In the analysis of the data it was considered the outline of subdivided
fractions, having in the fractions the periods (seasons) and in the sub fractions the vegetable parts, in the
delineation in randomized blocks with 6 repetitions. The content of essential oil (OE) was expressed on dry
weight basis and it was extracted through the vapor dragging method. The results showed that catuaba and
negramina didn’t present seasonal variability in the production of essential oil; it was also observed that
interaction doesn’t exist between times and vegetable parts for both species. However, seeking to optimize
the handling operations in function of the seasons and the largest production of essential oil, the harvest of
catuaba should be accomplished in the winter season (0,21% OE leaves and 0,16% OE branches) and the
harvest of negramina in the autumn season (0,18% OE leaves and 0,065% OE branches).
