Gas chromatography—mass spectrometry analysis of the volatile oils of two Teucrium polium varieties

Essential oil composition and nutrient analysis of selected medicinal plants in Sultanate of Oman

“…Linalyl acetate, β-Eudesmol, ledeneoxide (II), and α-trans-Bergamatene, on the other hand, were not detected in J. excelsa. Similarly, DL-Limonene was only 1.05% in T. polium as compared to 49.58% in J. excelsa. The percentage composition of β-Pinene, α-Camphenolene aldehyde, β-Bourbonene, β-Elemene, α-Humulene, α-Selenine, α-Cadinol, and Delta-Cadinene etc.…”

“…The author reported 30 chemicals with the major constituents, germacrene and pinene. Kamel and Sandra, on the other hand, compared the essential oil composition of two varieties of T. polium growing in Egypt and Qatar, reported 64 volatile components from both the oils [49] . In their study, too, the components varied between two verities and two locations.…”

Chemical composition of essential oil ofTeucrium polium subsp.capitatum (L.) from Corsica

“…album, both from Egypt, were dominated by sesquiterpenes: β-eudesmol, γ-and δ-cadinenes, spathulenol for the former, patchouli alcohol and cadinols for the latter. 19 Teucrium polium subsp. capitatum L. is a perennial, pubescent, aromatic plant, 20-50 cm high, with greengreyish leaves and white flowers, which appears from June to August.…”

Composition of the essential oil of Teucrium ramosissimum Desf. (Lamiaceae) from Tunisia

“…The high content of sesquiterpenes alcohols could be responsible of the antispasmodic effects observed by the natives of the region of Gafsa. 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. [8][9][10][11] Conversely, δ-cadinene, the major component of T. ramosissimum, was also identified as the main constituent in the oil of T. stocksianum from the United Arab…”
