ABSTRACT

The antibacterial potential of leaf's essential oil (EO) from Brazilian pepper tree (Schinus terebinthifolius Raddi) against staphylococcal isolates from dogs with otitis externa was evaluated. The minimum inhibitory concentration of EO ranged from 78.1 to 1,250 fg/mL. The oil was analyzed by GC and GC/MS and cytotoxicity tests were carried out with laboratory animals.

ABSTRACT

Over the last five years, collection and periodic observation in the Tapacurá Ecological Station, São Lourenço da Mata, Pernambuco, Brazil, have been carried out to produce a systematic ecological inventory of grasshopper distribution within the station based on the classifying criteria for Acridoidea, providing new data on families, subfamilies, tribes, genera and species related to the various types of vegetation and environments the station affords.


Através de procedimento de coletas e observações periódicas, ao longo de cinco anos, na Estação Ecológica do Tapacurá, São Lourenço da Mata, PE, procedeu-se a um inventário sistemático-ecológico da distribuição dos gafanhotos da estação, adotando-se critérios classificatórios de Acridoidea com novos assinalamentos de famílias, subfamílias, tribos, gêneros e espécies, relacionados aos diversos tipos de vegetação e ambientes da estação.

ABSTRACT

O óleo essencial obtido por hidrodestilação das folhas de Eugenia punicifolia, coletados a partir de duas regiões de Matas Serranas do Estado de Pernambuco (Serra Negra e Brejo da Madre de Deus), foi analisado por CG/EM. O monoterpeno oxigenado, linalol (SN: 44,0 por cento, BMD: 61,2 por cento), foi o componente principal do óleo de ambas amostras. Cerca de 66,2 por cento da constituição dos voláteis da amostra proveniente de SN e 74,2 por cento de BMD referem-se aos monoterpenos oxigenados, enquanto 33,6 por cento da amostra de SN e 20,5 por cento de BMD são sesquiterpenos oxigenados, sendo o b-cariofileno o mais abundante (SN: 22,7 por cento, BMD: 16,2 por cento). Com exceção do a-cadinol, presente apenas no óleo proveniente do Brejo da Madre de Deus, a constituição química de ambas as amostras foi à mesma, variando apenas o percentual relativo de seus constituintes.


The essential oils obtained from the leaves of Eugenia punicifolia by hydrodistillation, which were collected from two different locations of Pernambuco (Serra Negra and Brejo da Madre de Deus), have been investigated by GC/MS. Linalol was found to be the main component of this oil from SN (44,0 percent) and BMD (61,2 percent). About 66,2 percent of the oil constituents from SN and 74,2 percent from BMD are oxygenated monoterpenes, with predominance of beta-cariofileno (SN: 22,7 and BMD: 16,2 percent). With exception of a-cadinol, present only in the oils from plants colleted in Brejo da Madre de Deus, the chemical composition of both samples was quite similar, the only difference was the relative content among their components.
