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

<p>The chemical composition of essential oils isolated from the aerial parts of <i>Heracleum lehmannianum, Prangos pabularia, Pseudohandelia umbellifera</i> and <i>Pulicaria salviifolia</i>, all of them growing in Uzbekistan, were determined by GC-MS analysis. The main components of the oil from <i>H. lehmannianum</i> 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 <i>cis</i>-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 <i>P. pabularia</i>, 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 <i>P. umbellifera</i>. The essential oil of <i>P. salviifolia</i> had a much more complex composition which was dominated by 4-terpineol (13.4%), α-cadinol (5.7%), 6-<i>epi</i>-shyobunol (5.2%), γ-terpinene (5.0%), δ-cadinene (4.4%), α-terpinene (3.5%).</p
