RESUMO: 

Canela (Ocotea odor&#xED;fera Veil.) e gua&#xE7;atonga {Casearia sylvestris Swartz) s&#xE3;o importantes
esp&#xE9;cies medicinais da flora brasileira. Este trabalho teve como objetivo estudar a produ&#xE7;&#xE3;o de &#xF3;leo
essencial em fun&#xE7;&#xE3;o da &#xE9;poca de colheita da mat&#xE9;ria-prima vegetal proveniente de popula&#xE7;&#xF5;es naturais de
canela e gua&#xE7;atonga. Na an&#xE1;lise dos dados considerou-se o esquema de parcelas subdivididas, tendo
nas parcelas as &#xE9;pocas (esta&#xE7;&#xF5;es do ano) e nas subparcelas as partes vegetais (folhas, galhos e cascas),
no delineamento em blocos casualizados com 6 repeti&#xE7;&#xF5;es. A extra&#xE7;&#xE3;o de &#xF3;leo essencial (OE) foi expresso
com base no peso seco e extra&#xED;do por arraste a vapor. Os resultados mostraram que as esp&#xE9;cies estudadas, 
canela e gua&#xE7;atonga, apresentaram variabilidade sazonal na produ&#xE7;&#xE3;o de &#xF3;leo essencial; verificou-se tamb&#xE9;m, 
para ambas esp&#xE9;cies, que existe intera&#xE7;&#xE3;o entre &#xE9;poca de colheita e partes vegetais. A colheita defolhas (0,86% OE) 
e galhos (0,83% OE) de canela deve ser realizada na esta&#xE7;&#xE3;o do ver&#xE3;o e de cascas (1,37% OE) na primavera. 
Para a gua&#xE7;atonga, recomenda-se apenas a retirada de biomassa foliar, considerando a baixa produ&#xE7;&#xE3;o de 
&#xF3;leo nos galhos (0,14%); as folhas devem ser colhidas na esta&#xE7;&#xE3;o do outono (1,0% OE), visando o manejo 
sustent&#xE1;vel aliado &#xE0; m&#xE1;xima produ&#xE7;&#xE3;o de &#xF3;leo essencial.

ABSTRACT: 

Production of essential oil of canela (Ocotea odor&#xED;fera Veil.) and gua&#xE7;atonga (Casearia
sylvestris Swartz) in function of the harvest time. Canela (Ocotea odor&#xED;fera) and gua&#xE7;atonga (Casearia
sylvestris) are important medicinal species of the Brazilian flora. This work had as objective studies the
production of essential oil in function of the harvest time of the vegetable raw material originating from natural
populations of canela and gua&#xE7;atonga. 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 (leaves,
branches and bark), 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 the studied species, canela and gua&#xE7;atonga, present seasonal variability in the production of
essential oil; it was also verified, for both species, that interaction exists between harvest time and vegetable
parts. The harvest of leaves (0,86% EO) and branches (0,83% EO) of canela should be accomplished in
summer season and of bark (1,37% EO) in the spring. For gua&#xE7;atonga, it is just recommended the retreat of
foliate biomass, considering the low oil production in the branches (0,14%); the harvest of leaves (1,0% EO)
should be accomplished in the autumn season, seeking the sustainable management ally to the maxim
production of essential oil.

Key words: medicinal plants, essential oil, non-woody forest products, seasonal chemical variability, Mata
Atl&#xE2;ntica.
