The objective of this study was to evaluate the essential oils (EOs) obtained from two medicinal plants belonging to the genus Ocimum sp. These were compared in terms extraction yield and analysis of EOs compounds using GC/MS (content, chemical composition and quantitative dosage of some compounds: linalool, estragole and eugenol). Ocimum basilicum L., fam. Lamiaceae with 2 cultivars: Yellow basil (Ocimum basilicum L., 'Aromat de Buzău' variety), Purple basil (Ocimum basilicum cv. purpurascens, 'Seraphim' variety) and Holy basil (Tulsi) was used in the experiments. Extraction yields obtained: 5 ml EO/1 kg plant material for Yellow basil, 1 ml EO/1 kg plant material for Purple basil and 0.9 ml EO/1 kg plant material for Tulsi. Twenty-six compounds of the Yellow basil, sixteen compounds of the Purple cultivar and twenty-eight compounds in Tulsi and were identified using GC/MS. Linalool (46.70%-48.52%), Estragole (31.50% for the 'Aromat de Buzău' variety) and Eugenol (13.18% for the 'Seraphim' variety and 35.85% for the Tulsi) were dosed quantitatively and identified as the main and common compounds, for the essential oils obtained from the two species of Basil.
