Chemical Composition of the Essential Oil of Aerial Parts of Thymus ciliatus (Desf.)

Abstract

The essential oil of the aerial parts of Thymus ciliatus (Desf.) belonging to the Lamiaceae family, was obtained by steam distillation and analyzed by GC-FID and GC-MS. 75 components were identified corresponding to 95.57% of the total oil. The major constituents of the oil were: elemol (6.80%), carvacrol (5.86%), γ-muurolene (5.18%), β-sesquiphellandrene (5.09%), bicyclogermacrene (5.04%), β-pinene (4.49%) and curcumene (4.20%), together with other compounds at relatively low levels: 1,8-cineol (3.66%), β-eudesmol (2.92%), β-bisabolene (2.81%), β-silinene (2.75%), camphor (2.64%), germacrone (2.34%), α-zingiberene (2.12%), δ-cadinene (2.08%), caryophyllene oxide (1.90%), spathulenol (1.88%), □-caryophyllene (1.88%), ar-turmerone (1.79%), α-pinene (1.52%), limonene (1.52%), selina-4,11-diene (1.46%), curzerenone (1.41%), germacrone B (1.37%), bornyl acetate (1.31%), β-farnesene (1.28%), borneol (1.23%), myrtenal (1.16%), zingiberenol (1.15%) and sabinene (1.13%). These results differ from those of previous studies reported on this species collected from other regions of Algeria and Morocco.

Chemical Composition and Antioxidant Activity of Thymus ciliatus (Desf.) Benth. Essential Oils of Algeria

“…In previous studies, 29 compounds were identified with a ratio of 96.6% to 98.2%, 17 18 components representing 99.6%, 18 15 components representing 97.41%, 19 24 components representing 99.87%, 20 75 components representing 95.57%, 21 and 50, 54, and 55 components, representing 98.6%, 99.5%, and 99.3% of the total essential oil in the vegetative, flowering, and post-flowering stages of growth, respectively. 22 The difference in the detection of the No. of compounds and the total percentage of the selected compounds can be attributed to the detection technique, picking area, and time, as climatic conditions have a major impact on the chemical composition of essential oils in terms of quality and quantity.…”

Clonal micropropagation of Thymus vulgaris L.

“…Thymol is of particular value due to its antiseptic, bactericidal and disinfectant properties. There is evidence of its use against antibiotic-resistant body microflora [1][2].…”
