ABSTRACT

The essential oil of the leaves and fine stems of Aniba canelilla (Kunth) Mez collected in the city of Manaus, AM, Brazil, were obtained by hydrodistillation and analyzed by GC/MS. Forty-two components were identified, of which 1-nitro-2-phenylethane, as expected, was the major (71.2%-68.2%).

Key words: Aniba canelilla, Lauraceae, essential oil composition, 1-nitro-2-phenylethane.


RESUMO

Os óleos essenciais das folhas e dos galhos finos de Aniba canelilla (Kunth) Mez coletada na cidade de Manaus, AM, Brasil, foram obtidos por hidrodestilação e analisados por CG-EM. Quarenta e dois componentes foram identificados, dos quais 1-nitro-2-feniletano, como esperado, foi o que apresentou maior porcentagem (71,2%-68,2%).

Palavras-chave: Aniba canelilla, 1-nitro-2-feniletano, composição química de óleos essenciais.


 

 

Aniba canelilla ( Kunth) Mez (Lauraceae) (syn: Aniba elliptica A. C. Sm., Cryptocarpa canelilla Kunth), locally known as "casca-preciosa", is a large tree endemic to South America. Bark infusions have been used to treat diarrhea, coughs, and as a antispasmodic and stimulant for the nervous system (Corrêa, 1984; Martins, 1989; Almeida, 1993). 1-Nitro-2-phenylethane and methyleugenol were the major compounds identified in the essential oil of A. canelilla (Gottlieb & Magalhães, 1960; Morais et al., 1972; Oger et al., 1994; Taveira et al., 2003). The percentage content of these two compounds are reported as depending on soil and the seasonal period of collections in the Amazon that was higher in the rainy season (Taveira et al., 2003). The alkaloids of A. canelilla have been reported (Oger et al., 1993). The fungistatic activity of 1-nitro-2-phenyletahane and the LD50 of a petroleum ether extract from this plant was determined (Oger et al., 1994). This paper relates the chemical composition of the oil obtained from the leaves and fine stems of A. canelilla.

The samples of A. canelilla were collected on the Instituto Nacional de Pesquisas da Amazônia (INPA) campus, in Manaus, in the state of Amazonas, Brazil, in november 2001. A voucher especimen (#210071) was kept in the Herbarium of INPA. The leaves (188g) and fine stems (80g), dried at room temperature for 7 days, were subjected to hydrodistillation for 4h, using a Clevenger-type apparatus to produce oil yields of 0.8% and 0.2%, respectively. GC/MS analysis was performed on a Finnigan Mat INCOS XL GC/MS system, equipped with a DB-5MS (30m x 0.25mm; 0.25mm film thickness) fused silica capillary column; helium was used as carrier gas, adjusted to a linear velocity of 32 cm/s (measured at measured at 100ºC); split flow was adjusted to give a 20:1 ratio, and septum sweep was a constant 10mL/min. Splitless injection of 1mL, of a 2:1000 hexane solution; injector and detector temperature was 250ºC; programmed oven temperature was 60ºC-240ºC at 3ºC/min. the carrier gas was helium. Injection and oven-programming temperature were the same as above. EIMS: electron energy, 70 eV; ion source temperature and connection parts: 180ºC. Individual components were identified by comparison of both mass spectrum and their GC retention data with those of authentic compounds previously analyzed and stored in the data system, and by comparison of mass spectra with those in the data system libraries and cited in the literature (Adams, 1995). Components, retention indices, and percentages are listed in Table 1.

 

 

As reported in the literature (Gottlieb et al., 1960; Morais et al., 1972) in previous studies of the oil of A. canelilla, 1-nitro-2-phenylethane was found to be the major component. According our results the leaf and fine stem oil of the present sample furnished also a high content of 1-nitro-2-phenylethane (leaves: 71.2%; fine stems: 68.2%). The content of this component in the oil of the stem bark of A. canelilla, that were previously reported presented 89.8% (Oger et al., 1994) and 48.6%-94.3% (Taveira et al., 2003). To the best of our knowledge the chemical composition of the stem oil of A. canelilla is being reported here for the first time.
