چکیده
Abstract. The aim of this comparative research was to determine the chemical composition, antioxidant and antibacterial activities methanolic extracts essential oils (EOs) Artemisia absinthium aerial parts from five different regions (Bizerte, Zaghouan, Kasserine, Gabes Tozeur). polyphenol flavonoid contents significantly varied (P < 0.05) among studied with maximal observed in Zaghouan. Based on High Performance Liquid Chromatography results, quercetin isorhamnetin were main compounds their percentages region dependent. extract Zaghouan showed highest scavenging ability DPPH (IC50 = 31.46 ± 1.42 µg/mL). A. EOs found interestingly inhibit growth both Gram-negative Gram-positive bacteria strains. effect strongly related organoleptic EO quality. exhibited an important inhibitory inhibition zone estimated at 31 mm against Escherichia coli strain. composition obtained by GC-MS analysis showing presence thirty-five compounds. Camphor (49.70 2.34 %) chamazulene (25.41 0.61 constituents. These results suggested that north have a high potential for selecting varieties rich bioactive volatile phenolic Resumen. El objetivo de esta investigación fue determinar y comparar la composición química, las actividades antioxidantes antibacterianas los extractos metanólicos aceites esenciales (AE) partes aéreas cinco regiones (Bizerta, Los contenidos polifenoles flavonoides variaron significativamente 0,05) entre estudiadas con máximos observados en De acuerdo resultados cromatografía líquida alta resolución, quercetina isorhamnetina fueron compuestos principales sus porcentajes dependieron región. extracto metanólico mostró mayor capacidad secuestrante µg mL-1). Se descubrió que diferentes inhibían manera interesante el crecimiento cepas bacterias Gram-negativas Gram-positivas. efecto antibacteriano estuvo fuertemente relacionado calidad organoléptica del AE. AE exhibió un importante inhibidor halo inhibición estimado frente una cepa coli. La se obtuvo mediante análisis presencia treinta compuestos. alcanfor camazuleno constituyentes. Estos sugirieron norte tienen alto potencial para seleccionar variedades ricas bioactivos volátiles fenólicos.
