Hydrodistillation of two Ocimum sanctum [Ocimum tenuiflorum] cultivars (Shayma and Rama) resulted in the isolation of 0.41 and 0.43% of oils (w/v) on fresh weight basis, respectively. GC and GC-MS analysis of Shayma resulted in the identification of 34 constituents comprising 98.3% of the oil, of which the major ones were methyl eugenol (67.8%) and (E)-caryophyllene (17.1%). On the other hand, GC and GC-MS analysis of Rama resulted in the identification of 39 constituents comprising 98% of the oil, where eugenol (46.2%), (E)-caryophyllene (27.6%) and beta -elemene (16.3%) were the major constituents of the oils.
