Constituintes voláteis de espécies de asteraceae na Amazônia
The Asteraceae family consists of about 1100 genera and around 25000 species and is well represented in the Amazon region. Aiming to contribute to the knowledge of the chemical composition of its essential oils, the following species were studied: Baccharis tridentata Vahl, Cosmos caudatu Kunth, Eup...

Aiming to contribute to the knowledge of the chemical composition of its essential oils, the following species were studied: Baccharis tridentata Vahl, Cosmos caudatu Kunth, Eupatorium amigdalinum Lam, Eupatorium candoleanum Hooker, Eupatorium conyzoides Mill., Eupatorium cf. klenoides H.B.K., Mikania lindleyana DC., Pectis elongata Kunth, Porophylum ruderalle (Jacq.) Casso and Viguiera nervosa Gardner. The oils were obtained from the dried material by hydrodistillation, and the chemical composition by gas chromatography-mass spectrometry, in a FINNIGAN INCOS-XL system, using a DB-5MS silica capillary column, helium as carrier gas and a temperature program of 60°C-240°C (3°C/min). The main components identified in the oil from Baccharis tridentata were: benzaldehyde (22.9%), b-caryophyllene (13.5%), germacrene D (23.1%) and benzyl benzoate (16.1%); from Cosmos caudatus: caryophyllene oxide (27.2%); from Eupatorium amigdalinum: b-caryophyllene (12.3%), germacrene D (15.5%) and caryophyllene oxide (17.4%); from Eupatorium candoleanum: b-selinene (11.2%) and spatulenol (13.8%), from Eupatorium conyzoides: germacrene D (16.8%); from Eupatorium cf. klenoides: germacrene D (10.4%) and caryophyllene oxide (30.1%); from Mikania lindleyana: b-caryophyllene (64.1%) and cedr-8(15)-en-9a-ol (17.9%); from Pectis elongata: perylaldehyde (55.2%); from Porophylum ruderalle: spatulenol (10.1%) and from Viguiera nervosa: a-pinene (32.2%), b-pinene (21.8%), bicyclogermacrene (17.6%) and spatulenol (10.3%). In the essential oils of the studied species, a predominance of sesquiterpenes was observed as main components, mainly b-caryophyllene (12.5%-64.1%), caryophyllene oxide (17.4%-30.1 %) and germacrene D (10.4%-23.1 %). A família Asteraceae é constituída por cerca de 1100 gêneros e em torno de 25000 espécies sendo bem representada na Amazônia. Visando contribuir para o conhecimento da composição química de seus óleos essenciais realizou-se o estudo das seguintes espécies: Baccharis tridentata Vahl, Cosmos caudatu Kunth, Eupatorium amigdalinum Lam., Eupatorium candoleanum Hooker, Eupatorium conyzoides Mill., Eupatorium cf. klenoides H.B.K., Mikania lindleyana DC., Pectis elongata Kunth, Porophylum ruderalle (Jacq.) Casso e Viguiera nervosa Gardner. Os óleos foram obtidos do material seco através de hidrodestilação, e a composição química por cromatografia de gás-espectrometria de massas, em sistema FINNIGAN INCOS-XL, utilizando-se coluna capilar de sílica DB-5MS, hélio como gás de arraste e programa de temperatura de 60°C-240°C (3°C/min). Os principais componentes identificados no óleo de Baccharis tridentata foram: benzaldeído (22,9%), b-cariofileno (13,5%), germacreno D (23,1 %) e benzoato de benzila (16,1 %); de Cosmos caudatus: óxido de cariofileno (27,2%); de Eupatorium amigdalinum: b-cariofileno (12,3%), germacreno D (15,5%) e óxido de cariofileno (17,4%); de Eupatorium candoleanum: b-selineno (11,2%) e espatulenol (13,8%), de Eupatorium conyzoides: germacreno D (16,8%); de Eupatorium cf. klenoides: germacreno D (10,4%) e óxido de cariofileno (30,1 %); de Mikania lindleyana: b-cariofileno (64,1 %) e cedr-8(15)-en-9a-ol (17,9%); de Pectis elongata: perilaldeído (55,2%); de Porophylum ruderalle: espatulenol (10,1%) e de Viguiera nervosa: a-pineno (32,2%), b-pineno (21,8%), biciclogermacreno (17,6%) e espatulenol (10,3%). Nos óleos essenciais das espécies estudadas observou-se a predominância de sesquiterpenos como componentes principais, principalmente do b-cariofileno (12,5%-64,1%), óxido de cariofileno (17,4%-30,1 %) e germacreno D (10,4%-23,1 %). 2023-02-24T17:31:20Z 2023-02-23 2023-02-24T17:31:20Z 2000-07-06 Resumo COUTO, Hilma Alessandra Rodrigues do; ZOGHBI, Maria das Graças Bichara.
