The diploma thesis describes the essential oil of the Peucedanum ostruthium (Apiaceae) from
four different populations (Styria, Carinthia and Salzburg), that were grown from seeds in
Groß- Enzersdorf. The variability of the essential oil between the populations and the plant
parts has been investigated by GC/MS.
β-Phellandrene, E-β-ocimene and α-humulene determine the composition of the essential oil
of the flowers.
Leaves were higher in sabinene, germacrene-D and β-caryophyllene than the inflorescences,
whereas the flowers were richer in β-phellandrene, Z-β-ocimene, α-humulene than the leaves.
The quantity of essential oil varies greatly with the leaves` age.
The fruits were rich in β-phellandrene (more than 60%) and α-pinene (2-40%) and obtained
only small percentages of sesquiterpenes, mainly β-caryophyllene and α-humulene.
The results illustrate that there are significant variabilities in the quantity of the different
essential oil components between the populations and between different plant agents.
The population A was very rich in myrcene, whereas the populations C and D had higher
concentrations in sabinene and Z-β-ocimene.
The concentrations of the essential oil components of population B were between those of
Population A and C/D.
