Composition of the volatile oils of Satureja spicigera C. Koch Boiss. and S. macrantha C. A. Mey from Iran

Abstract

The essential oils of the aerial parts of Satureja spicigera (C. Koch) Boiss. and S. macrantha C. A. Mey., from Iran, have been analysed by GC and GC-MS. Forty-three compounds in the oil of S. spicigera, representing 97.4% of the total oil, and 48 compounds in the oil of S. macrantha, representing 92.1%, were identified. The oil of S. spicigera was rich in monoterpenes (89.9%) with thymol (37.3%) as the major compound, but the oil of S. Aerial parts of the plants were dried at room temperature, cut into small pieces and hydrodistilled using a Clevenger-type apparatus for 4 h. The oils were dried over anhydrous sodium sulphate and stored at 4-6°C. Identification and Quantification of the Oil ComponentsFID-GC was carried out using a Varian GC 3600 chromatograph with DB-5 (methyl phenyl siloxane, 30 m × 0.25 mm i.d., 0.25 µm film thickness) or DB-1 (60 m × 0.25 mm i.d., 0.25 µm film thickness); carrier gas, He; split ratio, 1:15, and flame ionization detector. Temperature programme, 60°C for 2 min, rising at 5°C/min to 240°C; injector temperature, 250°C; detector temperature, 260°C.GC-MS was performed on a cross-linked 5% methyl phenyl siloxane (HP-5, 30 m × 0.25 mm i.d., 0.25 µm film thickness) or DB-1 (see GC): carrier gas, He; split ratio, 1:15; quadruple mass spectrometer (Hewlett-Packard 5973) operating at 70 eV ionization energy.

Chemical Composition, Antibacterial and Radical Scavenging Activity of Essential Oils from Satureja macrantha C.A.Mey. at Different Growth Stages

“…Furthermore, a significant amount of sesquiterpene hydrocarbons (11.4%) were found at the flowering stage. Our results were in agreement with previous research where carvacrol, p-cymene, γ-terpinene and thymol were found as the marker volatiles of S. macrantha [14][15][16]. The thymol content was higher at the flowering stage compared to the other two stages.…”

“…The highest EO yield was recorded at the flowering stage (1.8%) while the lowest content was observed at the fruiting stage (1.4%). The yield values observed in the present study were comparable to those previously reported by Sefidkon and Jamzad [14] and Gohari et al [16], who found values ranging from 0.30% to 1.48%. The highest EO yield at the flowering stage is a usual phenomenon observed in many MAPs, in particular with those belonging to the Lamiaceae family [34,35].…”

Biological and Chemical Comparison of Natural and Cultivated Samples of Satureja macrantha C.A.Mey.

“…Additionally, its leaf part is used as food flavoring [8]. In the literature, there are several studies on its essential oil content and biological activities [8][9][10][11]. However, this is the first study on the chemical contents and biological activities of the ethanol extract of S. macrantha, and also on the cultivated S. macrantha.…”

Presence of monoterpene synthase in four Labiatae species and Solid-Phase Microextraction- Gas chromatography-Mass Spectroscopy analysis of their aroma profiles

“…[123] Essential oils of these plants consist of various monoterpenes and sesquiterpenes, as well as their derivatives, such as alcohols, aldehydes, esters, and acetates. [456] Terpenoids are formed from the condensation of dimethylallyl pyrophosphate (DMAPP) and isopentyl pyrophosphate (IPP), to give geranyl diphosphate (GPP), farnesyl diphosphate (FPP), or geranyl geranyl diphosphate (GGPP). [789] Terpene synthases in plant kingdom may fall into two categories.…”
