The essential oil steam-distilled from the whole plant of S. baluchistanica was characterized for its physicochemical properties and chemical composition. The oil obtained in 0.15% yield consisted of methyl benzene (1.87%), ethyl benzene (0.09%), xylene (0.13%), pentyl benzene (0.09%), 2, 3-dimethyl-3-ethyl pentane (0.52%), linalyl acetate (traces), methyl ethyl benzene (traces), 4-Tr-butyl cyclohexane (traces), trans-sabinone hydrate (0.07%), 2-methyl-4-hexyl hexanone (0.04%), isobutyl benzene (0.09%), phenyl methyl ketone (0.29%), m-menth-1, 8(9)-diene-5-ol (0.08%), cumene (0.94%), n-decane (1.30%), methyl benzaldehyde (0.15%), 1-methyl-4-isopropyl-1,3-cyclohexadiene (0.15%), 4-ethyl-1-octyn-3-ol (0.09%), pinene-oxide (0.10%), limonene-4-ol (0.17%), isocarvomenthone (1.17%), trans-pinocarvone (0.34%), eucarvone (1.51%), verbinone (0.55%), pulegone (5.38%), dec-3-en-2-one (0.52%), dec-4-en-2-one (0.44%), thymol (0.65%), cis-p-menthadiene-2, 8-ol-1 (3.71%), carveol (12.34%), chavicol (0.84%), .beta.-terpinene-3,4-oxide (0.14%), 2-methyl terephthaldehyde (2.30%), sabinol (15.83%), trimethyl benzaldehyde (0.14%), .gamma.-muurolene (7.23%), isolongifolene (0.10%), 1-phenyl-4-methyl-octane (0.19%), .gamma.-cadinene (0.79%), .alpha.-cadinene (0.14%), .beta.-bisabolene (0.55%), .beta.-elemene (1.16%), .beta.-selinene (1.08%), .beta.-caryophyllene (0.03%), humulene (0.28%), pinocarveol (2.76%), methyl chavicol (3.49%) and some unidentified sesquiterpenes and phenolic components. The essential oil of the S. baluchistanica was unique among umbellifer because no other member of the family contained such a large number of components; 109 compounds were detected in the oil and .apprx. 50 of these were identified.
