Pinus sylvestris L. - syn.Pinus nigra Mill. - Pinaceae - Scots pine, Gemeine Kiefer, Wald-Kiefer, Waldföhre, Rotföhre

Evergreen tree, native from Central Europe to Siberia.

„The four most abundant monoterpenes usually emitted from Pinus sylvestris were α-pinene, 3-carene, camphene, and β-pinene. Emissions of individual monoterpenes were highly correlated to each other and increased exponentially with temperature.“

„Influence of season on the terpene composition of Pinus halepensis and Pinus sylvestris was investigated. The essential oil of twigs and needles from a preselected plot of pines was investigated from October to June… In P. sylvestris, the average composition was 49.2% α-pinene, 30.1% sabinene, 14.9% β-pinene and 7.9% limonene in the essential oil of twigs; 69.5% α-pinene, 14.9% camphene, 9.1% β-pinene, 3.6% sabinene and 2.8% limonene in the essential oil of needles. The maximum amount of sabinene coincides with the minimum of α-pinene, both in twigs and needles essential oil from P. halepensis and P. sylvestris. The month-to-month changes in the oil composition are statistically significant for the most part. It is of interest to point out the decrease of sabinene content of needles essential oil in comparison with the twigs essential oil, with the simultaneous increase of terpinolene in P. halepensis and camphene in P. sylvestris.“

„Conifers produce the greatest amounts of terpenes among all plant families. In P.sylvestris the heart wood contains 8% resin consisting of 25% monoterpenes.“ The six major monoterpenes found in oeloresin samples of Swedish P.sylvestris populations were α-pinene (8-15%), β-pinene (5-24%), δ-3-carene (23-54%), myrcene (2-20%), limonene (3-14%), and β-phellandrene (7-23%).

„Oils of Pinus sylvestris L. produced from plant material collected from different locations in Lithuania have been investigated by GC and GC/MS. The oil content in many samples was approximately 1 mL/100 g (dry weight) with few exceptions when it was slightly higher or lower. More than 70 constituents were identified (64 positively and 10 tentatively) in the oils. α-Pinene (18.5-33.0%) and δ-3-carene (9.1-24.6%) were dominating constituents with the only one exception when the germacrene-4-ol content in one of the samples was 13.2%. The important bornyl acetate content varied from 0.5% to 3.0%. The main sesquiterpenes were β-caryophyllene, germacrene D, bicyclogermacrene, δ-cadinene, γ-cadinene, germacrene D-4-ol, cubenol (2.0-5.1%) and α-cadinol (1.9-7.7%).“

„…the distinctive odor is due to esters, mainly (-)-bornyl acetate… Turpentine oil and needle oils are antiseptic and secretolytic.“
