It has a pantropical distribution and about 30 genera in the Amazon. Annona, Xylopia, Duguetia and Guatteria are the most representative. The Cananga and Ylang-ylang oils (Cananga odorata var. macrophylla and C.odorata var. odorata) from Asia are commercially important and are used in fine perfumes, for example Chanel 5. A group of researchers from the Botany Department of MPEG is promoting the botanical and chemical survey of the Amazonian aromatic flora. As a research fellow engaged in the activities of the group, I was responsible for contributing to the study of the essential oil of Xylopia cayennensis Maas (sample A: 0.5%), Guatteriajuruensis Diels (sample B: 0.1%), X. nitida Dunal (sample C: 0.6%), X. emarginata Mart. (sample D: bark, 0.1%; sample E: leaves, 0.3%) and Guatteriopsis blepharophylla (Mart.) R.E. Fries (sample F:0.5%), aiming their chemiosystematic knowledge and biological activities. The plants were collected at the Mocambo Reserve, CPATU/EMBRAPA, and at the Ananim Village, in Peixe-Boi. The essential oils were analyzed by GC-MS (gas chromatography-mass spectrometry) to identify their volatile constituents. The main components of X.cayennensis leaf oil were: spatulenol (35.4%), a-pinene (19.2%) and b-pinene (18.7%); of G.juruensis leaf oil, spatulenol (77.1%); of X.nitida leaf oil, g-terpinene (44.1%), p-cymene (13.7%) and a-terpinene (12.6%); of X. emarginata were myrtenal (30.2%), verbenone (16.9%) and (E)-pinocarveol (9.6%) and from the leaves was spatulenol (73.0%); from the wood oil of Guatteriopsis blepharophylla were spatulenol (21.5%) and an isomer of a-humulene (55.1 %). It was observed that the oils of the species studied contain only mono- and sesquiterpenes, a characteristic of Cananga oils. The biological assays for fungicide and insecticide activity are being completed with the participation of Dr. Cleber Bastos, phytopathologist at CEPLAC. PPG-7/European Community. A família Annonaceae, de hábito predominantemente arbóreo e arbustivo, é constituída de 130 gêneros e 2500 espécies. Apresenta distribuição pantropical e cerca de 30 gêneros na Amazônia. Annona, Xylopia, Duguetia e Guatteria são mais representativos. Os óleos de Cananga e Ylang-ylang (Cananga odorata var. macrophylla e C.odorata var. odorata) da Ásia, tem importância comercial e são usados em perfumes finos, como por exemplo o Chanel 5. Um grupo de pesquisadores do Departamento de Botânica do MPEG promove o levantamento botânico e químico da flora aromática da Amazônia. Como bolsista de IC, engajada nas atividades do grupo, coube-me contribuir com o estudo do óleo essencial de Xylopia cayennensis Maas (amostra A: 0,5%), Guatteriajuruensis Diels (amostra B: 0,1 %), X.nitida Dunal (amostra C: 0,6%), X.emarginata Mart. (amostra D: cascas, 0,1%; amostra E: folhas, 0,3%) e Guatteriopsis blepharophylla (Mart.) R.E. Fries (amostra F:0,5%), visando o seu conhecimento quimiossistemático e as suas atividades biológicas. As plantas foram coletadas na Reserva Mocambo, do CPATU/EMBRAPA e, na Vila de Ananim, em Peixe-Boi. Os óleos essenciais foram submetidos à análise por CG-EM (cromatografia de gás I espectrometria de massas) para identificar seus constituintes voláteis. Os principais componentes do óleo das folhas de X.cayennensis foram: espatulenol (35,4%), a-pineno (19,2%) e b-pineno (18,7%); do óleo das folhas de G.juruensis foi espatulenol (77,1 %); do óleo das folhas de X.nitida foram g-terpineno (44,1%), p-cimeno (13,7%) e a-terpineno (12,6%); do óleo das cascas de X.emarginata foram mirtenal (30,2%), verbenona (16,9%) e (E)-pinocarveol (9,6%) e das folhas foi espatulenol (73,0%); do óleo da madeira de Guatteriopsis blepharophylla foram espatulenol (21,5%) e um isômero do a-humuleno (55,1 %). Observou-se que os óleos das espécies estudadas contém somente mono- e sesquiterpenos, uma característica dos óleos de Cananga.
