 "The monoterpene and sesquiterpene hydrocarbons of a commercial sample of Pinus mugo essential oil were isolated by a combination of techniques involving chromatography, distillation and preparative GLC. Eleven monoterpenes were identified by their IR spectra and TLC of their mercuric acetate adducts. IR and mass spectroscopy were employed to identify the following seven sesquiterpenes: β-caryophyllene, α-humulene, γ-muurolene, α-muurolene, α+β-selinene and γ-cadinene. Bornyl acetate was also present as a contaminant among these hydrocarbons." \\

+Freshly steam-distilled essential oils of P.mugo contained only traces of p-cymene (0.05-0.1%) and higher amounts of β-caryophyllene (4.6-5.4%). Main components of these oils were α-pinene (13-25%), δ-3-carene (16-26%), β-pinene (3-15%) and β-phellandrene (2-8%). Commercial oils (Germany) showed mean values of α-pinene (24.4%), δ-3-carene (17.8%), β-pinene (9.8%) and β-phellandrene (8.2%). Old oils showed elevated values of p-cymene (1-2%) and small amounts of β-caryophyllene (0-0.8%). \\

 "The chemical composition of the essential oil of the needles and twigs of dwarf pine (Pinus mugo Turra) growing wild in Serbia was investigated. The oil was analysed by GC/MS and the major constituents found were δ-3-carene (23.9%), α-pinene (17.9%), β-pinene (7.8%) and β-phellandrene (7.2%)." \\

+Abies alba Mill. - Pinaceae -  (European) silver fir, **Weißtanne**, Silbertanne
+Evergreen coniferous tree, up to 50m high, native to Central and South Europe, cultivated there; bark gray, with resin blisters; leaves needle-like, apex notched or rounded, upperside dark green, lowerside glaucous to whitish-green; pollen cones blue/violet/red, 1-3cm long, seed cones green when young, turning red-brown, up to 16cm long. \\

+"The analyses were performed on the commercial essential oil of Abies alba obtained from fresh green summits of young branches by steam distillation. The plant material was collected from the teritory of Montenegro. The composition of the oil was determined by GC and GC/MS. The main constituents were β-pinene (32.8%), α-pinene (17.3%), camphene (16.7%), bornyl acetate (9.0%), limonene (6.1%) and β-phellandrene (4.9%)." \\

+"This study investigates the isoprene and monoterpenes emission from A. alba in France... A dynamic cuvette method was used. Limonene was the predominant monoterpene emitted, followed by camphene, α-pinene and eucalyptol. No isoprene emission was detected... The standard emission rate (303 K) and β-coefficient averaged for limonene, camphene and α-pinene were respectively of 0.63 μg gdw-1 h-1 and 0.06 K-1. For eucalyptol, the standard emission rate (T=303 K and PAR=1000 μmol m-2 s-1) was 0.26 μg gdw-1 h-1. This classified A. alba as a weak monoterpenes emitter." \\

+Needles of Abies alba contain glycosidically bound maltol, which is cleaved during the drying of the needles on the forest floor, contributing to the characteristic note present in European (fir) forests warmed by the sun. \\

+"The composition of the essential oil of twigs of individual trees of Abies alba Miller from Corsica was investigated by CC, GC (RI), GC-MS and 13C-NMR. Among the 65 identified compounds, [[http://en.wikipedia.org/wiki/Limonene|limonene]], β-phellandrene, α-pinene, camphene and β-pinene were found to be the major components. Fifty-three oil samples were analysed and the results were submitted to chemometric analysis (K-means clustering and principal component analysis). Two groups were distinguished within the essential oils. Samples belonging to the first group (64% of the samples) were characterized by a very high content of limonene (mean value 46.1%). Conversely, the mean composition of the samples of the second group (36% of the samples) was dominated by camphene, α-pinene and limonene. Such a chemical composition is reported for the first time within A. alba essential oils." \\
