Abstract

The variations in the volatile constituents of hydrodistilled essential oil of spathes from ten varieties of Phoenix dactylifera L. including Kabkab (KAB), Shahani (SHA), Piarom (PIA), Hanaei (HAN), Tovarz (TOV), Shakri (SHK), Magti (MAG), Ghasb (GHS), Siah (SIA) and Gioni (GIO) were studied by GC/FID and GC/MS techniques. The highest Yield of spathes oil were found to be 0.36%. for Tovarz while Piarom and Siyah varieties each with 0.03% declared the lowest content of essential oil. Twenty four compounds were detected in the spathes oil. As evidenced by the results obtained, in the spathes oils of Phoenix dactylifera L., Shakri cultivar afforded the highest content of methoxylated aromatics (89.95%) from the total identified compounds. 3,4-dimethoxytoluene was found to be the major component in Gioni essential oil with 82.17%. This compound showed the lowest percentage in Shahani oil with 36.74%. The other major chemical components among all the varieties investigated were 2,6-dimethoxytoluene (6.89- 15.95%), farnesyl acetone (E,E) (1.74-20.85%), methyl geranate (1.1-5.60%), geranyl acetone(1.31-4.81%) and pmethylanisole (0.53-4.43%) respectively. Tovarz variety showed the maximum content of aliphatic aldehydes, oxygenated mono- and sesquiterpenes and fatty acids with 6.11, 5.86, 31.58 and 1.05% respectively. As indicated by the results, methoxylated aromatics showed the highest contribution in the chemical composition of spathes essential oil of P. dactylifera varieties while oxygenated sesquiterpenes and monoterpenes were among the quantitatively important components.
