Abstract
Investigations with solid sampling gaschromatography of separate leaves and of hydrodistilled oil of Juniperus communis L. var. saxatilis Pall. growing in Norway at an altitude of 1000-1300 m above sea level, showed a terpinen-4-ol content varying from traces to about 1 % in separate leaves and up to 16-17% in hydrodistilled oil of uncomminuted leaves and twigs.
