International journal of pharmaceutical and clinical research, 2017
Objective: The objective of the study was to extract the essential oil and to determine the physicochemical properties, chemical composition of the essential oil from Myrtus communis leaves by using GC-MS. Methods: 500 g of the powdered material (dried leaves) was subjected to hydro-distillation using Clevenger-type apparatus for 3 hours and the essential oil was dried over anhydrous sodium sulphate. The physicochemical properties essential oil such as solubility, density, specific gravity, refractive index, optical rotation, specific rotation, acid value, saponification value and ester value were determined, which are used to determine the quality of essential oils extracted from plant leaves. The chemical composition of the essential oil of Myrtus communis leaves was analysed using GC-MS. Results: The yield of essential oil of Myrtus communis leaves was 0.463 0.001 g/100 gram of dry sample which is 0.463 0.001 % (w/w) with pale yellow colour and pleasant odour. The essential oil of Myrtus communis leaves was slightly soluble in water and ethanol while it was soluble in chloroform, petroleum ether and ethyl acetate. The essential oil was subjected to GC-MS analyses, twenty eight components representing 99.949 % of the total oil composition. Conclusion: The present study indicates that the extraction of essential oil from Myrtus communis leaves and GC-MS analysis, the essential oil of this plant have a potential of secondary metabolites which can be exploited as a good source of bioactive substances.

The present study reports chemical composition, antidiabetic, anti-inflammatory and antioxidant potential of essential oils from leaves and twigs of Myrtus communis L. subsp. communis from Turkey. Essential oils were obtained separately from leaves and twigs of Myrtus communis subsp. communis (MC) by hydrodistillation using a Clevenger-type apparatus. Chemical compositions were determined using GC/MS. Antidiabetic, anti-inflammatory and antioxidant activities of essential oils were tested by α-amylase inhibitory, 5-lipoxygenase inhibitory and DPPH/ABTS radical scavenging methods, respectively. The major compounds of essential oil of Myrtus communis subsp. communis leaves (MCLEO) were α-pinene (35.6%), 1,8-cineole (28.3%), linalool (10.5%), and limonene (8.2%), while the major constituents of essential oil of Myrtus communis subsp. communis twigs (MCTEO) were α-pinene (30.7%), 1,8-cineole (23.5%), p-cymene (13.3%) and limonene (11.9%). MCLEO and MCTEO showed good and moderate radical...

Myrtus communis L. is one member of the Myrtaceae family. It is one of the important medicinal plants in the Zagros region of Iran. The Essential oils include a large percentage of compounds called terpenes. In this study, the chemical composition of essential oils of Myrtus (Myrtus communis L.) was identified by the GC-MS method. Results showed that essential oils of populations from different regions have a series of similar compounds, but different in quality and quantity. In fact, they have several organic compounds such as hydrocarbons, alcohols, ketones, aldehydes, ethers, esters, oxides and other volatile oil and so on. Percentage of essential oils in different populations were variable. Essential oil of "Basht" population has 35 compounds such as 1,8-cineole, linalool, αpinene and lynalyl acetate. Essential oils of "Dehno-Rostam" population has 30 compounds include 1, 8 cineole, linalool, α terpineol, α-pinene. Essential oils of "Sarab-Bahram" population has 19 compounds include α-pinene, 1,8cineole, linalool, and α terpineol. Essential oils of "Keveshk" population has 29 compounds such as 1,8-cineole, αpinene, linalool, and α-terpineol and Essential oils of "Tang-Tamoradi" population has 25 compounds include Eugenol, δ-3-carene, 1,8-cineole, and α-terpineol. Aqueous extracts of those populations were evaluated, and the results showed that they have antibacterial properties against Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa, but have not any antifungal activity (Aspergillus oryzae).

The chemical composition of essential oils obtained by hydrodistillation from Tunisian wild growing myrtle ripe fruits, leaves and floral buds was examined by GC and GC-MS. The yields of hydrodistilled oils obtained from different plant parts were: leaves 0.5%, floral buds 0.2% and ripe fruits 0.02%. Significant differences were found in the concentration of main constituents of the oils: α-pinene [48.9% (floral buds), 34.3% (fruits), 23.7% (leaves)], 1,8-cineole [15.3% (floral buds), 26.6% (fruits), 61.0% (leaves)]. The leaves oil contained less linalool than floral buds and ripe fruits oils. Tunisian myrtle is characterized by the absence of myrtenyl acetate.
Essential oil constituents of leaves and fruits of Myrtus communis L. from Iran
Planta Medica, 2009
Myrtus communis L. is an evergreen aromatic plant growing wild in Iran. Leaf samples were collected from two origins and in two different growth stages. Myrtle fruits were collected at full ripening stage. The oils of all samples were obtained by hydrodistillation using a Clevenger-type apparatus and their constituents were analyzed by GC and GC-MS. The major oil components of leaves of two origins at flowering stage were α-pinene (3.8 -23.0 %), 1,8-cineole (9.9 -20.3 %), limonene (5.5 -17.8 %), linalool (12.3 -17.6 %) and α-terpinyl acetate (1.8 -7.0 %). The leaf oil compositions at fruit ripening stage was highly similar to those of flowering stage as 1,8-cineole (24.0 %), α-pinene (22.1 %), limonene (17.6 %), linalool (11.4 %), linalyl acetate (4.5 %), α-terpinyl acetate (2.2 %), and geranyl acetate (1.2 %) were main components. Major constituents of fruit oil were α-pinene (28.6 %), 1,8-cineole (26.7 %), limonene (18.0 %), α-terpinyl acetate (5.4 %), linalyl acetate (3.4 %) and linalool (2.3 %).

This study aims to evaluate the chemical composition and biological effects of an endemic Algerian species Myrtus nivellei belonging to the Myrtaceae family. The aerial parts of the plant were submitted to hydrodistillation and analysed with gas chromatography - mass spectrometry (GC-MS). This oil was yielded 0,75% (w/w). The GC-MS revealed that 1,8 cineole is the most abundant component (53,44%) while other compounds were present in high contents: 2,2,6,7-tetramethyl-10-oxatricyclo [4.3.0.1(1,7)]- decan-5-one (11,73%), trans ocimene (7,54%), linalyl propirionate (6,81%) and lavandulyl acetate (5,24%). In addition ethanolic extract of studied plant was prepared. Total phenol, tannin, flavonoid, and condensed tannin?s contents were determined using Folin-Ciocalteu, aluminum chloride and vanillin colorimetric methods, respectively. Three tests were used for the investigation of antioxidant activity of both extract and oil. Strong antioxidant activity was shown mainly by crude extract....
Myrtus communis L. as source of a bioactive and safe essential oil
Food and Chemical Toxicology, 2015
In Algeria, Myrtus communis L. is distributed throughout the Tell Atlas and the coastal regions of Algiers and Constantine. The leaves are used in respiratory disorders, diarrhea and hemorrhoids. The aims of this work were to evaluate the antifungal and anti-inflammatory potential of well characterized essential oils (EO). Since EO can be applied by inhalation, dermal application and oral administration, we used several mammalian cell lines to assess safe bioactive doses. The chemical composition of two samples was investigated by GC-FID, GC-MS and 13 C NMR spectroscopy. Monoterpene derivatives are the main compounds: α-pinene (50.8 and 33.6%), 1,8-cineole (21.9 and 13.3%), linalool (2.7 and 14.8%), and linalyl acetate (0.5 and 9.5%). The antifungal evaluation revealed that the oils were more active against Cryptococcus neoformans (yeast) and Epidermophyton floccosum, Microsporum canis, Trichophyton rubrum (dermatophytes). The anti-inflammatory potential was evaluated using an in vitro model of lipopolysaccharide (LPS)-stimulated macrophages. Assessment of cell viability was made through the MTT assay. Both oils were able to significantly inhibit NO production, without affecting cell viability, in concentrations up to 0.64 mg/mL. These promising results, disclose bioactive concentrations of Myrtle essential oils with a safety profile suggesting a potential oral and topical application or use by inhalation.
