Composition of the essential oils from Peucedanum cervaria and P. alsaticum growing wild in the Urban Area of Vienna (Austria)

Abstract

The composition of the essential oil from the different above ground plant parts of Peucedanum cervaria and P. alsaticum (Apiaceae) collected in the urban area of Vienna has been studied. P. cervaria fruits and inflorescences had 1.5 and 1.8% essential oil, respectively. All the oils of P. cervaria were dominated by monoterpenes, with the main components being β-pinene (7-58%), α-pinene (7-22%), sabinene (up to 22%), and β-phellandrene with limonene (6-21%). P. alsaticum fruits afforded 0.3-0.4% essential oil. These oils were made up mainly by α-pinene (11-40%), sabinene (16-34%) and β-phellandrene (12-31%). Stems and leaves produced only very small amounts of essential oil (< 0.05%). Besides monoterpenes, these oils contained also E-nerolidol (5-22%), spathulenol (up to 18%), dodecanal (up to 7.5%) and caryophyllene oxide (up to 7%).
