Essential oils of Phlomis leucophracta, Phlomis chimerae and Phlomis grandiflora var. grandiflora from Turkey

The Effect of Reaping Times on Volatile Components of Natural Phlomis L. (Lamiaceae) Taxa in the Lakes District of Turkey

“…Seventy volatile components of Phlomis leucophracta were determined by SPME analysis and the essential compounds were (E)-2-hexenal (8.74%), limonene (14.56%) and β-caryophyllene (22.45%). Celik et al (2005) found β-caryophyllene (20.2%), α-pinen (19.2%) and limonene (11%) in P. leucophracta. β-caryophyllene and limonene were the volatile components.…”

Chemical Composition and Antimicrobial Activity of the Essential Oil of Algerian Phlomis bovei De Noé subsp. bovei

“…& Bal., growing in central East and Southeast Anatolia, an endemic Phlomis of Turkey, was characterized by the predominance of: β-caryophyllene (24.2%), germacrene D (22.3%) and caryophyllene oxide (9.2%) [10]. The essential oils of three other Turkish Phlomis species (Table 3) have also been studied previously [11]. The essential oil of P. leucophracta consisted mainly of β-caryophyllene (20.2%), α-pinene (19.2%) and limonene (11.0%), while in P. chimerae the principal compounds were β-caryophyllene (31.6%), α-pinene (11.0%), germacrene D (6.1%), limonene (5.5%) and linalool (4.7%), and in P. grandiflora var.…”

“…The essential oil of P. leucophracta consisted mainly of β-caryophyllene (20.2%), α-pinene (19.2%) and limonene (11.0%), while in P. chimerae the principal compounds were β-caryophyllene (31.6%), α-pinene (11.0%), germacrene D (6.1%), limonene (5.5%) and linalool (4.7%), and in P. grandiflora var. grandiflora: germacrene D (45.4%), β-caryophyllene (22.8%) and bicyclogermacrene (4.9%) have been identified among the most abundant constituents [11]. The oils of P. bovei De Noé and of the other Mediterranean species: P. grandiflora var.…”

“…The oils of P. bovei De Noé and of the other Mediterranean species: P. grandiflora var. grandiflora [11], P. cretica [8], P. fruticosa [3,7,8], P. samia [8], P. linearis [10], P. lanata [9], P. leucophracta [11] and P. cimereae [11], presented great amounts of the sesquiterpenoids germacrene D, E-β-farnesene and β-caryophyllene. In accordance to these results, in our study besides the presence of germacrene D (21.45%) and β-caryophyllene (7.05%), hexahydrofarnesyl acetone (5.84%) has been also identified among the most abundant compounds, which could be considered as the biosynthetic predecessor of the above referred sesquiterpenoids, from the well known mevalonic acid pathway [12].…”

Chemical composition of essential oil and antioxidant activity of leaves and stems of Phlomis lurestanica

“…[7] Chu et al, [8] reported geranial (16.5%), linalool (13.3%), cis-geraniol (7.4%), β-myrcene (6.2%), 1,8-cineol (5.3%), 4-terpineol (5.1%), and myristicin (5%) as the major compounds in the aerial parts of P. umbrosa in the flowering stage. The major compounds of P. chimera were β-caryophyllene (31.6%), α-pinene (11.0%), and germacrene D. [9] The chemical composition of the essential oils and antioxidant properties of P. lurestanica extracts have not been previously reported. Therefore, the aim of the present study was to evaluate the oil composition and antioxidant properties of its methanol extracts.…”
