Abstract
The essential oil of 2 varieties of the seed of B. cylindricum, with 1.4 and 1.8% yield, was investigated for its percentage yield, physicochemical properties and chemical composition. The Safed (white) zira khar was composed of .alpha.-pinene (2.3%), camphene (1.0%), myrcene (0.7%), .rarw. 3-carene (0.7%), .alpha.-phellandrene (0.5%), limonene (13.7%), .gamma.-terpinene (3.5%) p-cymene (1.4%), unidentified monoterpene (0.4%), myristicin (67.2%), dillapiole (traces), cuminaldehyde (2.1%), unknown ketone (1.1%), elemol (4.0%) and juniper camphor (1.1%) while the siah (black zira khar) contained .alpha.-pinene (0.3%), camphene (0.3%), .DELTA.3-carene (0.2%), limonene (0.7%), .gamma.-terpinene (0.6%), unknown monoterpenes (0.3%), .beta.-elemene (0.6%), .beta.-caryophyllene (4.5%), humulene (2.7%), .beta.-selinene (10.9%), 1-cadinene (13.4%), bornyl acetate (1.0%), myristicin (4.1%), dillapiole (11.0%), elemicin (39.3%), an unknown ketone (0.9%), elemol (3.0%) and juniper camphor (6.2%). The seed of these species were used as an adulterant of B. persicum.
