Abstract: 

The essential oil of the aerial parts of Senecio selloi Spreng. DC. was extracted
by hydrodistillation and analyzed by GC/MS. Nineteen compounds were identified, representing
99.9% of the total. The main compounds were found to be sesquiterpene hydrocarbons (71.3%),
most of them with a bisabolane skeleton (59.4%). The major constituent was α-zingiberene
(54%), followed by monoterpene α-isolimonene (16%). The essential oil was also tested against
two Gram-positive and two Gram-negative bacterial species, three yeasts, and an algae. From
the strains assayed, only Bacillus subtilis ATCC 6633 showed susceptibility (MIC and MBC =
4400 µg/mL) to the essential oil.

Key words: Antimicrobial activity, essential oil, Senecio selloi Spreng. DC.  a

Resumo: 

Composição e avaliação da atividade antimicrobiana do óleo essencial de
Senecio selloi Spreng DC. O óleo essencial das partes aéreas de Senecio selloi Spreng DC. foi
extraído por hidrodestilação e analisado por CG/EM. Dezenove constituintes foram identificados,
representando 99,9% do total. Os principais compostos fornecidos foram sesquiterpenos
hidrocarbonetos (71,3%), a maioria destes com esqueleto bisabolano (59,4%). O constituinte
majoritário foi a-zingibereno (54%), seguido do monoterpeno a-isolimoneno (16%). O óleo
essencial foi testado contra duas cepas Gram-positivas e duas Gram-negativas, três fungos
e uma alga. De todas as linhagens testadas somente Bacillus subtilis ATCC 6633 mostrou
suscetibilidade (CIM e CBM = 4400 µg/mL) para o óleo essencial.
