Composition of Peucedanum longifolium Waldst. & Kit. essential oil and volatiles obtained by headspace.

The present study reports the chemical composition ofPeucedanum longifoliumessential oil and headspace (HS) volatiles obtained from the fresh aerial parts. The major contributors of the essential oil were β-elemene (24.7%), (E)-β-ocimene (11.7%),cis-linalool oxide (furanoid, 5.7%), (Z)-β-ocimene (5.6%) and α-humulene (5.2%). HS analysis of the above ground plant parts has enabled the identification of thirty-one components, representing 98.7% of the total volatiles. The main constituents were: (E)-β-ocimene (28.5%), (Z)-β-ocimene (11.9%), α-pinene (8.9%), myrcene (8.5%),p-cymene (6.4%), limonene (6.3%), sabinene (6.0%) and α-phellandrene (5.6%). Twenty-six components were in common for both the oil and HS volatiles, which is 77.3% of the oil and 97.1% of the HS sample. [ABSTRACT FROM PUBLISHER]
