Ce travail vise l’étude de la composition chimique, de l’activité antioxydante et antimicrobienne de l’huile essentielle (HE) de Brocchia cinerea d’Algérie vis-à-vis de trois bactéries, d’un champignon. L’analyse chromatographique (CG/SM) a montré que l’HE de Brocchia cinerea est caractérisée par la présence du Beta.-Thujone (46,80), 1-Methyl-2-(1'-methylethenyl)-3'- ethenylcyclopropylmethanol (14,59) et du 1,8-Cineole (12,63), limonen-10-ol (9,47), accompagnés d’autres composés à des teneurs relativement faibles : 1(7),3,8-oMenthatriene (3,45), (-)-Camphor (2,11). L’activité antioxydante déterminée par le test DPPH a montré que l’HE présente un faible potentiel antioxydant avec l’IC 50 = 6652 μg/ml et IC 50 = 140.53 par FRAP, en comparaison à d’autres espèces de la famille des Asteraceae. Aux concentrations étudiées, l’essence a manifesté une forte activité antibactérienne et antifongique. Cette bioactivité est due principalement à la richesse de cette essence en Beta.-Thujone connu pour son efficacité contre les agents microbiens.

Reduction Capacity

In the Myrtaceae family, the species Eugenia involucrata DC., popularly known as "cerejeira-do-mato", is traditionally used for the antidiarrheal and digestive action of its leaves. However, no studies were found in the literature regarding its antimicrobial and antioxidant potential. In this context, the objective of the present study was to determine the chemical composition by gas chromatography coupled to mass spectrometry (GC-MS) to evaluate the antimicrobial activity by the broth microdilution technique and the antioxidant activity by the 2,2-diphenyl-1-picryl-hydrazila (DPPH) method of the essential oil of E. involucrata leaves. GC-MS identified 28 compounds, all sesquiterpenes, corresponding to 89.41% of the essential oil. The antimicrobial activity of the essential oil was observed for all Gram-positive bacteria tested (Staplylococcus epidermidis, Enterococcus faecalis, Bacillus subtilis and Staplylococcus aureus) and for yeast Candida albicans. The essential oil presented a reduction capacity of DPPH up to 66.81%, evidencing its antioxidant potential. It is suggested that the antimicrobial and antioxidant action of E. involucrata essential oil is related to the presence of the major compounds, elixene (26.53%), β-caryophyllene (13.16%), α-copaene (8.41%) and germacrene D (7.17%).
