abstract the hydrodistilled leaf and fruit oils of amoora rohituka wigth. et arn. cultivated in egypt was analyzed by gc/ms. forty components were identified in the fruit oil, while 20 components were identified in the leaf oil based on their retention indices and mass spectra. both oils were rich in sesquiterpenoids (90.4% and 87% in the leaf and fruit, respectively). sesquiterpene hydrocarbons represented 65.6% in leaf oil and 47.1% in fruit oil; while oxygenated sesquiterpenes constituted 24.8% in leaf oil and 39.9% in fruit oil. both oils exhibited significant antibacterial activity, but no antifungal activity.
