Abstract
The essential oil and the water cohobation oil of the seed of A. graveolens grown in the Jhelum and Lahore districts [Pakistan] was studied for the first time with respect to its physicochemical characteristics and chemical composition. For the 2 areas the essential oil was obtained in 2.5% and 2.6% yield while its composition is .alpha.-pinene (1.0, 0.5%), .beta.-pinene (1.5, 0.8%), mycrene (3.1, 6.1%), limonene (35, 37%), p-cymene (3.1, 2.5%), .beta.-elemene (3.5, 1.5%), .beta.-caryophyllene (4.1, 3.1%), .beta.-selinene (32.5, 28.5%), 3-isolbutylidene-3a,4-dihydrophthalide (0.7, 1.0%), carvone and dihydrocarvone (0.4, 1.0%), eudesmol (1.0, 0.5%), .gamma.-terpineol (0.3, 0.5%), n-butylphthalide (5.0, 7.2%), and sedanonic anhydride (8.0, 7.9%), respectively. The water cohobation, oils' yield and composition in the same order were 0.55% and 0.49% and .alpha.-pinene (traces, 0.5%), .beta.-pinene (traces, 0.3%), myrcene (2.0, 3.5%), limonene (2.8, 3.0%), p-cymene (1.0, 1.2%), .beta.-caryophyllene (2.4, 1.6%), humulene (1.4, 3.2%), .beta.-selinene (1.3, 1.1%), 3-isobutylidene-3a,-4-dihydrophthalide (0.6, 0.3%), carvone and dihydrocarvone (0.7, 1.2%), n-butylphthalide (25.0, 20.0%) and sedanonic anhydride (60.0, 63.0%).
