“…All analysed samples differed significantly from the Sardinian oil reported in the literature; [13] as for the main components, linalool was the only common component. Finally, from the taxonomic point of view, T. massiliense essential oils seem to be original in comparison with the two other Corsican Teucrium species previously investigated, [25,26] in which hydrocarbon, monoterpenes and/or sesquiterpenes were identified.…”

“…As part of our on-going chemical investigations of the essential oils of Teucrium species from Corsica and Sardinia, [25,26] the aim of the present study was, on the one hand, the characterization of essential oils of T. massiliense L. from both islands, using a combination of capillary GC-RI, GC-MS (EI and CI modes) and 13 CNMR spectroscopy after fractionation on column chromatography. We reported, for the first time, a real concentration determination via calibration curves and response factor calculations for each oil component.…”

Volatile components extracted from the aerial parts and separated organs of Corsican and Sardinian Teucrium massiliense have been studied. The chemical composition of essential oils obtained by hydrodistillation (HD) has been investigated using GC-RI, GC-MS (EI and CI modes) and 13 CNMR spectroscopy. For the first time, a real concentration via calibration curves and response factor calculations has been determined for each oil component. The concentrations of the major components were 6-methyl-3-heptyl acetate (23.83-18.16 g/100 g), 3-octyl acetate (10.55-6.95 g/100 g), isobutyl isovalerate (7.67-2.91 g/100 g), germacrene D (6.13-1.01 g/100 g) and linalool (6.63-5.23 g/100 g). To the best of our knowledge, the occurrence of 6-methyl-3-heptyl acetate as a natural product is reported for the first time. Furthermore, the chemical composition of volatile fractions emitted from the aerial parts and separated organs of T. massiliense L. has been studied by HS-SPME/ GC-RI and GC-MS after optimization of SPME parameters. Concerning the contribution of plant organs to the aromatic plant fingerprint, we noted that the flowers produced more volatiles than other organs. The volatile fractions obtained from the different organs were qualitatively quite similar to each other but differed in the percentages of their major components. Also, the influence of HS-SPME extraction parameters (equilibrium and extraction times and temperature) on the chemical composition of the plant volatile fraction is discussed.

“…5,7 Comparison of the above results with T. creticum from Cyprus, T. chamaedrys and T. flavum from Iran, show many differences regarding the main constituents of the oils.

The essential oil from aerial parts of Teucrium ramosissimum Desf. (Lamiaceae), endemic to North Africa, was isolated by steam distillation and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Seventy-four components were identified; the essential oil was mainly composed of sesquiterpene hydrocarbons and oxygenated sesquiterpenes at nearly the same amounts (41.9% and 42.3%, respectively). δ δ δ δ δ -Cadinene (19.97%), α α α α α -cadinol (9.93%) and germacradien-4-α α α α α -1-ol (8.68%) were the major compounds.

“…Also in the oils of T. oriental L. var. oriental, T. fruticans, T. abutiloides, T. salviastrum, T. turredanum, and T. betonicum, sesquiterpenoids such as β-caryophyllene, germacrene D, and α-humulene were reported to be the major components [8][9][10][11][12][13][14][15].In this paper the essential oil composition of Teucrium hyrcanicum, which is an endemic plant related to the Caspian sea area, is reported for the first time [16].Thirty-six components were identified in the oil of T. hyrcanicum representing 93.1% of the oil, and also forty-two components were characterized in the oil of T. chamaedrys ssp. chamaedrys representing 94.1% of the oil.…”

The genus Teucrium (Lamiaceae) is comprised of about 340 species widespread over the world. In the Flora Iranica, this genus is represented by 12 species [1]. Various species of the genus Teucrium are used as antiseptic, antipyretic, antiinflammatory, antispasmodic, antinociceptive, anti-rheumatic, anthelmintic, diuretic, hypoglycemic, diaphoretic, and tonic in folk medicine [2].Phytochemically, several diterpenoids, diterpenelactones, triterpenoids, flavonoids, and minor phenolic compounds have already been isolated from this plant and analyzed [3][4][5][6][7].A literature survey on the essential oil composition of some Teucrium species revealed that in T. melissoides, T. polium subsp. capitatum, T. haenseleri, and T. capitatum, monoterpenes such as α-pinene, β-pinene, p-cymene, and limonene were the main constituents. Also in the oils of T. oriental L. var. oriental, T. fruticans, T. abutiloides, T. salviastrum, T. turredanum, and T. betonicum, sesquiterpenoids such as β-caryophyllene, germacrene D, and α-humulene were reported to be the major components [8][9][10][11][12][13][14][15].In this paper the essential oil composition of Teucrium hyrcanicum, which is an endemic plant related to the Caspian sea area, is reported for the first time [16].Thirty-six components were identified in the oil of T. hyrcanicum representing 93.1% of the oil, and also forty-two components were characterized in the oil of T. chamaedrys ssp. chamaedrys representing 94.1% of the oil.The identified components with their percentages are given in Table 1. These components are listed in order of their elution from the DB-5 column.As it is shown, the oil of T. hyrcanicum consists of oxygenated monoterpenes (16.3%), sesquiterpene hydrocarbons (32.3%), and oxygenated sequiterpenes (24.9%). Hexahydrofarnesyl acetone (12.7%), linalool (11.7%) and E-β-farnesene (10.7%), dihydroedulane (8.6%), and ar-curcumene (8.5%) were the main constituents in this oil. As a result, in the oil of T. hyrcanicum, sesquiterpenes (61.7%) predominated over monoterpenes (16.3%).In contrast, the oil of T. chamaedrys ssp. chamaedrys is rich in sesquiterpenes (63.8%), with α-muurolene (15.3%), β-caryophyllene (15.0%), and Z-β-farnesene (7.6%) as the major components. Among the identified monoterpenes (26.5%) in this oil, α-pinene (7.9%), β-pinene (5.9%), and limonene (5.1%) are the most abundant.The composition of the essential oil of T. chamaedrys (subspecies not referred to) has been reported in the literature. Some differences in the quantity and quality of the oil composition may be due to different subspecies, chemotype, and geographic and climatic factors. For example, in two of them, germacrene D and β-pinene were reported as the main constituents [17,18].
