Essential Oil Details

Essential Name

: Baccharis dracunculifolia Essentail oil

Plant Name

: alecrim-do-campo

Plant Variety Name

: NA

Plant Tissue Name

: Aerial part

Introduction

The essential oil was extracted through hydro-distillation, and its chemical composition was determined using gas chromatography-mass spectrometry (GC-MS). Its antimicrobial properties were evaluated by measuring the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC) against eight bacterial and eight fungal strains using 96-well microtiter plates. The oil yield was 1.8 � 0.07%, with spathulenol (27%) and trans-nerolidol (23%), both oxygenated sesquiterpenes, identified as the predominant compounds among the 30 detected constituents.
