Composition of essential oils from four Apiaceae and Asteraceae species growing in Uzbekistan

The chemical composition of essential oils isolated from the aerial parts of Heracleum lehmannianum, Prangos pabularia, Pseudohandelia umbellifera and Pulicaria salviifolia, all of them growing in Uzbekistan, were determined by GC-MS analysis. The main components of the oil from H. lehmannianum were α-phellandrene (10.5%), 1-butanol (9.0%), δ-cadinene (6.2%), α-cadinol (5.7%), τ-muurolol (3.1%), 4-terpineol (2.4%) and α-muurolene (2.6%), while cis-allo-ocimene (17.6%), δ-3-carene (14.2%), limonene (7.6%), 2,4,6-trimethylbenzaldehyde (6.8%), α-terpinolene (6.1%), β-ocimene (4.3%), α-ocimene (4.2%), α-phellandrene (4.2%) were the major oil components in P. pabularia, and borneol (4.4%), t-cadinol (4.1%), α-humulene oxide (4.0%), caryophyllene oxide (3.6%), bornyl chloride (3.1%), β-pinene (2.9%) in P. umbellifera. The essential oil of P. salviifolia had a much more complex composition which was dominated by 4-terpineol (13.4%), α-cadinol (5.7%), 6-epi-shyobunol (5.2%), γ-terpinene (5.0%), δ-cadinene (4.4%), α-terpinene (3.5%).
