| Popis: | The essential oils obtained from aerial parts of Aloysia sellowii from two different collection locations Southern Brazil (A and B), were analyzed by GC, GC/MS, and chiral phase gas chromatography (CPGC). It was identified 48 compounds representing ca 93% and 91% of the oils of samples A and B, respectively. Besides them 1,8-Cineole, beta-pinene, sabinene, and beta-(Z)-santalol were the major components. In a preliminary biological screening the samples of essential oils of A. sellowii displayed strong activity in the brine shrimp lethality assay (LC50 = 2.85 µg mL-1) as well as antimicrobial activity against Gram-positive and Gram-negative microorganisms and two yeasts (MIC 1.7-16 mg mL-1). Os óleos essenciais obtidos das partes aéreas de Aloysia sellowii, coletadas em duas diferentes localidades (A e B) do sul do Brasil, foram analisadas por CG, CG-EM, e através de cromatografia gasosa com fases quirais (CGC). Dos quarenta e oito componentes identificados, representando cerca de 93 e 91% dos óleos das regiões A e B, respectivamente, 1,8-cineol, beta-pineno, sabineno e beta-(Z)-santalol foram os principais componentes. Um "screening" preliminar das duas amostras de óleos de A. sellowii mostrou atividade frente a Artemia salina (LC50 = 2,85 µg mL-1), além de exibirem atividade antimicrobiana frente a bactérias Gram-positivas e Gram-negativas e frente a leveduras (MIC 1,7-16 mg mL-1). |
