Composition of the essential oils of Ocimum canum, O. gratissimum and O. minimum.
The essential oils of OCIMUM CANUM, O. GRATISSIMUM and O. MINIMUM grown in S. Tomé, where they are used in Traditional Medicine mainly as febrifuge and for the treatment of respiratory diseases, were investigated. The essential oils were obtained from the aerial parts by hydrodistillation and subsequently analysed by GC, GC-MS and (13)C-NMR. (13)C-NMR SPECTROSCOPY proved to be an important tool, which can be very useful in the identification of most of the constituents. Major compounds in the volatile oil of O. GROTISSIMUM were thymol (48.1%) and P-cymene (12.5%). The essential oil of O. CANUM was characterized by its high content of TRANS-METHYL cinnamate (79.7%), whereas the most important oil constituent of O. MINIMUM was linalool (52.7%).
