Abstract The composition of essential oils of Leutea glaucopruinosa (Rech.f.) Akhani & Salimian comb, nov., and Zeravschania (Boiss. & Hausskn.) Salimian & Akhani comb. nov. were analysed by GC-MS. 49 compounds are identified in the former and 33 compounds in the latter, comprising a total of 76 compounds in both species. Both species were originally described under Peucedanum, which are transferred in this paper into Leutea and Zeravschania, respectively. The chemical compounds of the essential oils show that there are only seven common compounds between two species. The major compounds of L. glaucopruinosa are mostly monoterpene hydrocarbons and oxygenated monoterpenes, in which α-pinene (31.5%), sabinene (9.7%), β-pinene (9.2%), exo-fenchyl acetate (4.5%) are dominant. In Z. pastinacifolia sesquiterpene hydrocarbons and phenylpropanoids dominate with β-bisabolene (37.3%), 3,1-butyl-1.2-dimethoxy benzene (14.9%), 10,11-dimethylbicyclo[6.3.0]undec-(8)-en-9-one (12.9%), 4-t-butyl-1,2-dimethoxy benzene (6.8%), (E)-asarone (5.1%) and elemicine (4.1%) as major compounds.

Essential oils are widely used as functional ingredients for potential multi-purpose functional uses. Hydrosols, co-products of the distillation of plant material, are used in food and cosmetic industries and in biological agriculture, but their volatile composition is poorly investigated. The volatile fractions of essential oils and hydrosols from four less-studied 1,8-cineol-rich Eucalyptus species (E. parvula L.A.S. Johnson & K.D. Hill, E. cinerea F. Muell, E. pulverulenta Sims and E. pulverulenta baby blue Sims), cultivated in Tuscany in a system of organic farming, were characterized by solvent dilution (essential oils) or extraction (hydrosols) followed by GC-MS and by HS-SPME-GC×GC-TOFMS analysis. GC-MS analysis showed that essential oils were mainly constituted by oxygenated monoterpenes, particularly 1,8-cineole, with monoterpenes hydrocarbons up to 10.8%. Relative differences in the abundance of minor terpenes as limonene, α-pinene, γ-terpinene, p-cymene, terpinen-4-ol, α-terpineol, and alloaromandrene were pointed out and seem to be suitable for differentiation among EOs of the four different Eucalyptus species. Hydrosols of these species were characterized for the first time: they were mainly constituted by oxygenated monoterpenes (97.6–98.9%), with 1,8-cineole up to 1.6 g/L, while monoterpene and sesquiterpene hydrocarbons were detected only in traces. HS-SPME-GC×GC-TOFMS analysis also allowed providing metabolic profiling of hydrosols for the direct comparison and visualization of volatile components, pointing out the potentially different uses of these products as functional ingredients in food, beverage, and cosmetic industries.

Terpene compounds of Tanacetum macrophyllum as 1) essential oils, obtained by hydrodistillation (HD), 2) essential oil extracts, obtained by simultaneous hydrodistillation and extraction (SDE) and 3) volatiles, obtained by Static Headspace GC-MS analysis (HS) were processed. Monoterpenes were the most dominant (49.2%, 49.5% and 90.4%, respectively). Profiles of essential oils obtained by HD and SD were quite similar, with oxygenated monoterpenes (39.3% and 39.4%) being the most abundant. In HS volatiles oxygenated monoterpenes also dominated (57.4%). Total sesquiterpenes were abundant in HD and SDE volatiles (38.2% and 39.2%, resp.), where sesquiterpene hydrocarbons were prevalent (27.3% and 28.7%, resp.). Germacrene D was dominant in HD and SDE oils (22.0% and 23.3%, resp.) and 1,8-cineole in HS volatiles (34.3%). To our knowledge, this is the first use of Headspace technique on T. macrophyllum. Furthermore, this is the first comparison of different techniques of volatile extraction in T. macrophyllum.

Objective: The purpose of this study was to identify and characterize chemical constituents of Rosmarinus officinalis L. essential oils from Diyala Province, an eastern side of Iraq. Methods: Following hydrodistillation extraction of the leaves, gas chromatography–mass spectrometry (MS) was performed. Eighteen peaks were identified and compared to known compounds and MS patterns. Results: The two major components identified were eucalyptol (1,8-cineole) and L-camphor, and they represent 59% and 29%, respectively. In addition, α-terpineol, bornyl acetate, borneol, linalool, and β-terpineol were detected in 3.75, 2.83, 1.96, 1.22, and 0.65%, respectively. Conclusion: The present study showed that rosemary essential oils from Diyala Province of Iraq consisted mostly of oxygenated monoterpenes (>96%) and hydrocarbon monoterpenes are less than 1%. The latter suggest that hydrocarbon monoterpenes may undergo transformation due to atmospheric as well as microbiological metabolism which more studies are needed to confirm such suggestion.

Abstract Monoterpenes, the chemical constituents of essential oils found in plants, are known biologically active compounds. The present study was conducted to investigate the inhibitory effects of 30 monoterpenes including monoterpene hydrocarbons and oxygenated monoterpenes on seed germination and seedling growth of Amaranthus retroflexus, Chenopodium album and Rumex crispus under laboratory conditions. The monoterpenes were applied at contents of 10 and 20 μl for liquid compounds and 10 and 20 μg for solid compounds. The results show that most of the monoterpenes significantly inhibited seed germination and seedling growth of the tested plants. Oxygenated monoterpenes including β-citronellol, nerol and terpinen-4-ol completely inhibited seed germination and seedling growth of all tested plants. Their inhibitory effects were also stronger than that of the herbicide 2,4-D. In general, monoterpenes were less effective against seed germination and seedling growth of C. album as compared with R. crispus and A. retroflexus. Phytotoxic effects of monoterpene hydrocarbons were found to be lower than those of oxygenated monoterpenes. The alcohol derivatives of oxygenated monoterpenes were also found to be more phytotoxic as compared with their acetate derivatives. Based on the present results, it can be concluded that the oxygenated monoterpenes can be used as potential bio-herbicides.

Abstract Background and objective The constituents of sweet lemon essential oil (EO) have different biological and medical properties. The exploitation of sweet lemon residues in the production of EO is an important means of increasing natural products and disposing of those residues. The aim of this study was to evaluate the EO extracted from various sweet lemon residues such as leaves, flowers, and peels of fruits to find out their content of active substances. Materials and methods The EO of different residues of sweet lemon was isolated by hydrodistillation (HD) method, then they were analyzed by GC/MS. Data were statistically analyzed using ANOVA-1. Results The content of EO (%) was higher in peels than in flowers or leaves. Citronellal, nerol, and limonene were the major constituents of EO extracted from leaves, flowers, and peels, respectively. All detected components of various oils belonged to four chemical fractions (monoterpene hydrocarbons (MH), oxygenated monoterpenes (OM), sesquiterpene hydrocarbons (SH), and oxygenated sesquiterpenes (OS)). The MH was the major faction of peel EO while the OM was the major fraction of leaf and flower EOs. The SH and OS were formed as the minor fractions in all EOs. Conclusion Different variations were observed in sweet lemon EO extracted from various residues which lead to diversity in natural sources of EO production.

The Nigerian essential oils of fresh Pterocapus soyauxii leaf, leaf stalk and stem bark were isolated by hydro-distillation using the adapted all glass Clevenger’s apparatus designed to British Pharmacopeia specifications. Chemical compositions of the plant parts were characterized using Gas Chromatography-Mass Spectroscopy (GC-MS). The leaf essential oil contained 12 compounds, out of which 10 were identified accounting for 93.91% of it. Leafstalk oil had 20 major compounds, which were characterised; they constitute 95.47% of the oil. 11 compounds make up 78.61% of stem bark oil, out of which 7 were characterised, responsible for 76.30% of it. Prominent compounds in the leaf oil were cembrene (43.59%), a monocyclic diterpenoid, eremophilene (29.72%), and azulene derivatives (6.62%), which are polycyclic aromatic compounds. Leaf stalk oil was dominated by hexadecane (32.97%), cis- and trans- β-ocimene (11.60 and 7.74% respectively) and heptanol (8.39%). Major compounds in stem bark oil were neophytadiene (22.11%), 2-heptanol (19.27%) and 3,7,11,15-Tetramethyl-2-hexadecene-1-ol (14.35%). Other prominent compounds in the stem bark oil are 4-propyl-cyclohexene (4.83%), 3-Eicosyne (7.63%), 3,7,11-trimethyl-14-(1-methylethyl-[S-(E,Z,E,E)]-1,3,6,10-cyclodecatetraene (5.10%) and methyl-Z-5,8,11,14,17-Eicosapentaenoate (3.01%). Notable compounds of biological importance and in appreciable amounts in the oils include phytol (6.93%), squalene (1.14%) and ambrial (1.97%). Fragmentation patterns in the mass spectrum of some unidentified compounds are also presented which are unique features of the oils. Interesting classes of compounds in the three oils include monoterpenes, sesquiterpenes, diterpenes, naphthalenes, alcohols and hydrocarbons.

In Persian nutrition culture, drinking aromatic waters (hydrosols, distillate) has a long history as functional beverages or therapeutic remedies. The co-distilled water with essential oils, which contains partial amounts of more water-soluble volatile compounds are diluted and used as beverages. Since the solubility of volatile components is different in water, the overall composition, and thus the biological activities of aromatic waters seem to be different from the essential oils they were co-distilled with. Despite the essential oils, chemical constituents of many aromatic waters have not been evaluated scientifically. This research investigated hydrosols used for mental and neurological health maintenance in Persian nutrition culture and their chemical constituents. Constitutions of these hydrosols were extracted by liquid/liquid extraction method and identified by gas chromatography–mass spectrometry. Furthermore, cluster analysis was used to evaluate the relevance of these hydrosols chemical constituents. About 93 compounds were identified from 20 aromatic waters. the major or second major constituents were thymol (azarol howthorn, frankincense, lemon balm, valerian, shadab), phenethyl alcohol (damask rose, dog-rose, starflower), carvacrol (basil, creeping buttercup, lemon balm); eugenol (shadab, dog-rose, starflower, basil), camphor (yarrow and wormwood), carvone (oriental plane), caryophyllene (cuminum), cinnamaldehyde (Chinese cinnamon), p-cymen-7-ol (musk willow), limonene (lemon verbena), linalool and α-terpineol (bitter orange), menthol (date palm) and methyl 5-vinylnicotinate (olive). Although, these hydrosols prepared from plants belong to different genus and families, but cluster analysis showed obvious similarities between their chemical constituents. Results of this investigation showed in many cases that the constituents of aromatic waters are different from the pure essential oil.
