The composition of the essential oils from the needles, branches and female cones of four species of Pinaceae, Pinus pinea, P. halepensis, P. pinaster and P. nigra, has been analysed and comparative chemical evaluations were obtained. In P. pinea the major compound of the essential oils of all the three plant parts is limonene (58.9–62.5%), in P. halepensisα-pinene (18.1%–53.6%) and myrcene (13.7–42.1%), in P. pinasterα-pinene (24.7–40.4%) and β-pinene (21.7–29.2%), and in P. nigraα-pinene (28.4–61.7%).

The chemical composition of essential oils obtained by hydrodistillation from Tunisian wild growing myrtle ripe fruits, leaves and floral buds was examined by GC and GC-MS. The yields of hydrodistilled oils obtained from different plant parts were: leaves 0.5%, floral buds 0.2% and ripe fruits 0.02%. Significant differences were found in the concentration of main constituents of the oils: α-pinene [48.9% (floral buds), 34.3% (fruits), 23.7% (leaves)], 1,8-cineole [15.3% (floral buds), 26.6% (fruits), 61.0% (leaves)]. The leaves oil contained less linalool than floral buds and ripe fruits oils. Tunisian myrtle is characterized by the absence of myrtenyl acetate.

Myrtle (Myrtus communis L.) is a shrub spontaneously growing in the Mediterranean area. The leaf and fruit content of essential oils and phenolic compounds justify the wide use of the plant as medicinal and aromatic. Because of overexploitation of wild plants, a domestication process is in progress in different regions and the influence of the genotype variability on the chemical composition of fruit essential oils may be useful to breeding programs. Consequently, the analysis performed on a selected group of candidate clones growing in the same field collection in Sardinia is the object of this report. Forty-seven selections provided fully ripe fruits for essential oil extraction by hydrodistillation and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Only five candidate clones showed white fruits. The highest yield of essential oil was observed in the LAC31 genotype with 0.55 g·kg−1, while the samples BOS1, MON5, RUM4, RUM10, V4 and V8 showed values above 0.20 g·kg−1 and mo...

Chemical profile of essential oils of the Costa Rican native tree Myrcianthes storkii (Myrtaceae)
Cuadernos de investigación UNED, 2023
The genus Myrcianthes ranges from southern Florida to Chile, including the Caribbean, and the species Myrcianthes storkii is a shrub or tree found in Costa Rica and western Panama, in wet to very rainy, cloud, and oak forests (altitude 1300-3150m). Objective: To identify the chemical composition of essential oils from leaves, floral buds, and twigs of M. storkii of Costa Rica. Methods: We obtained the essential oils through hydrodistillation in a Clevenger-type apparatus. The chemical composition of the oils was done by GC/FID and GC/MS, using the retention indices on DB-5 and Carbowax types of capillary columns in addition to mass spectra. Results: The oils consisted mainly of terpenoids (55,45-87,75%). A total of 281 compounds accounted for 91,27-74,56% of the total amount of oils. The major constituents from the leaf oil were myrcene (17,44%), cis-calamenene (12,60%), α-pinene (5,48%), (E)caryophyllene (5,16%), limonene (3,91%), p-cymene (3,71%), 1,8-cineole (2,80%), and α-humulene (2,80%). The floral bud essential oil consisted mainly of α-pinene (15,23%), cis-calamenene (12,70%), myrcene (8,59%), 1,8cineole (4,26%), germacrene B (3,65%), α-humulene (3,55%), and (E)-caryophyllene oxide (2,93%). The major components of twig oil were cis-calamenene (11,31%), palmitic acid (7,99%), (E)-caryophyllene (4,68%),cadinene (3,28%), cubenol (3,24%), and (Z)-caryophyllene oxide (2,94%). Conclusion: The presence of a significant quantity of myrcene and cis-calamenene seems to be characteristic of this species.

The essential oils obtained from leaves of two Myrtus communis varieties (baetica and italica), growing wild in North Tunisia, were investigated by GC and GC-MS at their different phenological stages. The highest essential oil yield was observed at the flowering stage with 0.6% (w/w) for italica and 0.4% (w/w) for baetica and 49 compounds were identified. The main essential oil leaf compounds of both myrtle varieties, belonging to the monoterpene class, were a-pinene, 1,8-cineole, limonene and linalool and their percentages showed significant changes during the phenological stages.

The compositions of the essential oils obtained by hydrodistillation of the ripe fruits, flowering aerial parts and roots of Elaeoselinum asclepium (L.) Bertol subsp. meoides (Desf.) Fiori (Apiaceae) were determined by GC-MS analysis. All the analyzed parts were very rich in alpha-pinene (77.1%, 92.2% and 60.8%, respectively). Other compounds detected in appreciable amounts were beta-pinene (4.3%, 4.0% and 8.2%), and sabinene (11.9% in ripe fruits; 12.8% in aerial parts). The plant synthesizes different classes of monoterpenes, including pinane, camphane, thujane, menthane, and fenchane derivatives, besides some acyclic monoterpenes. Trace amounts of sesquiterpenes and diterpenes were also detected.

As a medicinal and industrial plant, Myrtle (Myrtus communis L., Myrtaceae) is widely used in pharmacological, food, and cosmetic industries. In the current study, variabilities in the leaf essential oil (EO) compositions of 23 Myrtle populations, collected from the natural habitats of different regions in Fars Province, Iran, were studied. The EO yields of the populations varied from 0.53% to 1.75% based on dry matter. According to GC/MS analysis, α-pinene (12.2-60.4%), 1,8cineole (6.2-27.3%), limonene (1.4-26.7%), linalool (0.7-21.0%), myrtenyl acetate (0-29.1%), and geraniol (0.3-8.3%) were the major compounds. Using the hierarchical cluster analysis, the myrtle populations in Fars province were classified into four groups based on the main EO components, namely I α-pinene/1,8-cineole, II α-pinene/1,8-cineole/linalool, III α-pinene/limonene/1,8-cineole and IV myrtenyl acetate/limonene/linalool. In conclusion, this study gave new insights into the breeding programs for obtaining potential plant materials through their commercial cultivations.
