Resumo: The aim of this study was determine (i) the chemical composition (ii) the antimicrobial 28 activity (antibacterial and antifungal) and (iii) the antioxidant activity by means of four 29 different antioxidant tests (DDPH, FIC, FRAP and TBARS) of the EOs of three aromatic 30 herbs, Coriander (Coriandrum sativum), celery (Apium graveolens) and bush-basil (Ocimum 31 minimum) widely used in Portugal. 32 There is a great variability of the compounds presented in the three tested essential oils. 33 Bush-basil EO had the highest total phenolic content (794.9 mg GAE/L) while coriander EO 34 had the lower total phenolic content (52.3 mg GAE/L). Since bush-basil had the highest TPC 35 it was expected to present a very high antioxidant profile, which was verified in 3 of the 4 36 assays (DPPH inhibition of 95.9%; FRAP values of 2.7 mmol Trolox/L; TBARS inhibition of 37 87.2%); coriander, despite the low TPC showed the highest inhibition in the FIC assay 38 (94.1%). 39 The bush-basil EO showed the highest antimicrobial activity, with MIC ranging between 40 0.6-5 μL/mL against bacteria and 0.04-2.5 μL/mL against yeasts. Both celery and coriander 41 EO had a very similar antimicrobial activity against all the tested strains. The antifungal 42 activity was higher in the bush-basil EO against M. racemosus and P. chrysogenum since it 43 was the only EO that showed growth inhibition on all the tested concentrations. A. alternata 44 showed great resistance against all the tested essential oils.
