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.

Chemical constituents of essential oils (EOs) obtained from stem and root of Tephrosia purpurea (Linn.) Pers. and Ipomoea carnea Jacq. were investigated by Gas Chromatography-Mass Spectrometry (GC-MS). Total lipid and oil content was high in the stem than the root of T. purpurea and I. carnea. Essential oils extracted from the stem and root of T. purpurea and I. carnea showed 9 and 8 compounds respectively. Hexadecanoic acid was found to be the principal constituent of stem (69.61%) and root (46.97%) of T. purpurea while 70.61and 88.89% for stem and root, respectively in the case of I. carnea. The findings of the present study suggest that T. purpurea and I. carnea EOs can be used as a source of hexadecanoic acid which could be used for industrial purposes. The essential oils of T. purpurea and I. carnea showed strong repellent activity for males (-0.73 and -0.70 for T. purpurea and I. carnea stem EO respectively) than females (-0.63 and -0.59 for T. purpurea and I. carnea stem EO respectively) against banana pseudostem weevil Odoiporus longicollis. The results indicated that the active compounds of essential oils from stems of T. purpurea and I. carnea can be explored as natural repellents for control of Odoiporus longicollis.

This study reports on the chemical compositions of the essential oil of Rosmarinus officinalis L. (Rosemary) grown in Mersin, Turkey. The essential oil of rosemary was obtained by hydrodistillation method, and the yield of rosemary oil was found to be about 1.2 % (v:w). The hydrodistilled volatile oil was analyzed by gas chromatography and mass spectrometry techniques. Forty-five components were identified in the essential oil of R. officinalis, which represented 100% of the total essential oils. The oxygenated monoterpenes content possessed the highest value, 64.78% of the oil, among which eucalyptol (33.15%) and camphor (10.31%) were the most abundant components. In addition, the oil contained mainly monoterpene hydrocarbons, sesquiterpene hydrocarbons, oxygenated sesquiterpenes, and diterpenes. The least amount of diterpenes were found in the content of the oil. Isopimara-9 (11),15-diene (0.14%) and α-springene (0.06%) were two compounds determined as diterpene compounds.

Objective: Essential oils extracted from the leaf of Euodia suaveolens have been reported. However, there is no published data on comprehensive report on the chemical constituents of the essential oils and the methods utilized to extract the essential oils from the plant. This research aimed to reveal and determine the chemical constituents of essential oils from the leaf of E. suaveolens. Methods: Essential oils of leaf of E. suaveolens were extracted by steam distillation and were analyzed utilizing Gas Chromatography-Mass Spectrometry (GC-MS) methods. Results: The GC-MS analysis revealed the presence of twenty-five different chemical constituents from the essential oils. The main chemical constituents of essential oils extracted from E. suaveolens’ leaves were as follows menthofuran (50.38 %), p-mentha-1,8-diene (14.34 %), limonen (10.99 %), evodone (5.55 %), α-curcumene (4.65 %), globulol (1.88 %), longipinenepoxide (1.66 %), and linalool (1.40 %). This present research found three compounds, namely p-mentha-1,8-diene, globulol, and longipinenepoxide that have never been reported by any researchers working with this plant. Conclusion: The results showed that E. suaveolens contains essential oils that are potential to be explored further and utilized as medicinal products against some ailments.

This study is aimed at the extraction and chemical analysis of the essential oils of the leaves and flowers of Lavandula stoechas L growing in northeastern Algeria. The hydrodistilled oils isolated from leaves (0.75%) and flowers (0.6%) were characterized by fifty-two and sixtyfour compounds, respectively. Gas chromatography–mass spectrometry (GC-MS) analysis demonstrated that both organs revealed the presence of fenchone and camphor as the major compounds. However, the highest percentage of fenchone (52.7%) was observed in the flowers oil; whereas, the percentage of camphor (25.94%) was significantly higher in the leaves oil in comparison with its content in flowers oil (15.52%). Other predominant compounds in leaves and flowers oils were, respectively, as follows: 1.8-cineole (4.84% and 4.02%), camphene (4.55% and 3.23%), bornyl acetate (3.06% and 4.43%), α-terpinolene (1.09% and 1.45%), viridiflorol (1.51% and 1.39%), and α- pinene (0.5% and 1.5%). The quantitative and qualitative data proved that the chemical profile of both organs of Lavandula stoechas native to Algeria was approximately close. The oil chemical composition is susceptible to the influence of environmental factors (soil, climate). The biological activity (antimicrobial and antioxidant) of the two oils from Lavandula stoechas L., native to this Algerian region is under study.

Phytonutrients, also called phytochemicals, are chemicals produced by plants. Foods and vegetables with phytonutrients have antioxidant and anti-inflammatory benefits. The aim of this study was to analyzed 4 parts of 3 lotuses phytochemical constituents by using gas chromatography mass spectrometry. Our results showed that different parts of lotus had a different chemical compound. The major chemical constituents in each extract are 6-Methoxy-2-[p-tolyl]cinchoninic acid (23.92%), Stigmastan-3, 5-diene (6.17%), 5(1H)-Azulenone, 2, 4, 6, 7, 8, 8a-hexahydro-3, 8-dimethyl-4-(1-methylethylidene)-, (8S-cis)- (24.44%), 2-Cyclohexane-1-carboxaldehyde, 2, 6-dimethyl-6-(4-methyl-3-pentennyl (18.15%), Stigmastan-3, 5-diene (24.04%), 2(1H)Naphthalenone, 3, 5, 6, 7, 8, 8a-hexanhydro-4, 8a-dimethyl-6-(1-methylethenyl)-(6.49%), 2-[p-Methoxyphenyl]-8-methylcinchoninic acid (12.98%), Ergosta-4, 6, 22-trien-3, beta, -ol (13.57%), and Stigmastan-3, 5-diene (26.05%). Therefore, Phytonutrients could also provide significant benefits for human’s health that eat plant foods.
