Composition of the essential oil of Phlomis persica Boiss and Phlomis chorassanica Bunge from Iran

Abstract

Two essential oil samples obtained by hydrodistillation from aerial parts of Phlomis persica Boiss. and Phlomis chorassanica Bunge. (Lamiaceae), were analysed by GC and GC-MS; 41 compounds in the oil of P. persica, representing 97.3%, and 42 compounds in the oil of P. chorassanica, representing 99.5%, were identified. Both essential oils were rich in sesquiterpenes (81.3% and 90.1%, respectively) with germacrene D (32.5% and 51.5%, respectively) as the major component.

Comparative analysis of essential oil components of three Phlomis species in Qinling Mountains of China

“…The oils of other species (P. anisodonta, P. bruguieri, P. bruguieri, P. cancellata, P. chimerae, P. chorassanica, P. cretica, P. cretica, P. ferruginea, P. fruticosa, P. grandiflora var. grandiflora, P. herba-venti, P. lanata, P. lanceolata, P. leucophracta, P. linearis, P. nissolii, P. olivieri, P. olivieri, P. olivieri, P. persica, P. persica, P. pungens, P. rigida, P. samia and P. samia) from Iran, Turkey, Greece and Italy are reported to be rich in germacrene D, ␤-caryophyllene, ␥-elemene, ␤-farnesene, limonene, bicyclogermacrene, ␤-selinene and hexadecanoic acid (>10%) [7][8][9][10][11][12][13][14][16][17][18][19][20][21][22][23], while samples collected from Yugoslavia were found to contain a low percentage of germacrene D, but to be rich in ␤-caryophyllene, (E)-methyl isoeugenol and ␣-asarone [15]. In contrast to the reports above, the essential oil of P. younghunsbandii from Tibet showed different qualitative and quantitative profiles, in which eugenol, hexadecanoic acid and 9, 12-octadecadienoic acid methyl ester were the major components [24].…”

“…Comparing the essential oil composition of Phlomis species many similarities are obvious. Germacrene D, the main compound of the essential oils of Phlomis species, was detected in almost all the Phlomis species studied, although in some species only in small amounts [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The oils of other species (P. anisodonta, P. bruguieri, P. bruguieri, P. cancellata, P. chimerae, P. chorassanica, P. cretica, P. cretica, P. ferruginea, P. fruticosa, P. grandiflora var.…”

Chemical composition and antimicrobial activity of the essential oil of Phlomis ferruginea Ten. (Lamiaceae) growing wild in Southern Italy

“…The other compound present in high concentration in the Iranian oils is β-caryophyllene, whose content is 6.7% in P. brugueri 19 and 25.0% in P. chorassanica. 17 The oils of P. brugueri extracted from plants grown in the southern 18 and northern 19 regions of Iran showed different compositions: the former has a high content of germacrene D (60.5%) accompanied by γ-elemene (16.5%) and germacrene B (7.1%); the latter shows germacrene D in a concentration of 23.6% accompained by 4-hydroxy-4-methyl-2-pentanone (15.0%) and β-caryophyllene (6.7%). Germacrene B (8.0%) was also detected in P. lanceolata.…”

“…Germacrene B (8.0%) was also detected in P. lanceolata. 18 Finally, the oil of P. persica 17 is characterized by germacrene D (32.5%) and (E)-β-farnesene (21.7%) as the main components. Phlomis ferruginea Ten.…”

Composition of the volatile oils of Phlomis lanceolata Boiss. & Hohen., Phlomis anisodonta Boiss. and Phlomis bruguieri Desf. from Iran

“…3,8,11 There are few reports on the essential oils content of members of this genus. [12][13][14][15][16][17] Antimicrobial activity of the essential oils of P. lanata 12 and P. fruticosa 5 have been studied. In addition, there is another study on the essential oil of P. fruticosa concerning antimutagenic activity.…”
