The essential oils from needles, twigs, bark, wood, cones and young shoots of Pinus mugo were analyzed by GC, GC/MS, and 1 H-NMR spectroscopy. More than 130 compounds were identified. The oils differed in the quantitative composition. The principal components of the oil from twigs with needles were 3-carene (23.8 %), myrcene (22.3 %), and α-pinene (10.3 %). The needle oil contained mainly α-pinene (18.6 %), 3-carene (11.3 %), and bornyl acetate (8.3 %). The oils from twigs without needles, young shoots, bark, and wood were dominated by 3-carene (28.6 %, 15.0 %, 18.5 %, and 34.6 %, respectively) and myrcene (23.4 %, 24.0 %, 24.6 %, and 9.4 %, respectively). In the cone oil (E)-β-caryophyllene was the main constituent (24.0 %).
