    The aim of this study was to isolate essential oils from Ocimum sanctum L leaves by Clevenger-hydrodistillation and microwave-assisted hydrodistillation. Components of the essential oil were then identified using Gas Chromatography Mass Spectrometry (GC-MS). Antimicrobial activity of these oils was determined by this diffusion method against Escherichia coli, the main component of the essential oils was geranial (24.74%) and neral (28.11%) for Clevenger-hydrodistillation method, while geranial (41.85%) and neral (29.07%) for the method microwave-assisted hydrodistillation. Our finding for antimicrobial test showed that essential oil of microwave-assisted hydrodistillation was more active than those of Clevenger-hydrodistillation. Antioxidant activity using DPPH assay of the essential oil of Clevenger-hydrodistillation was more active (IC50=513.1802 μg/mL) than those of microwave-assisted hydrodistillation (IC50=713.2279 μg/mL).
