“…Like that of Rasooli et al, 27 and Messaoud et al, 22 , α-pinene was determined as the major constituent of the essential oil in the recent study, while others have reported 1,8-cineole 2,5,11,26,32 or myrtenyl acetate 13,17 as the major constituent of the essential oil.…”

Abstract:Nosocomial pathogens are associated with increased hospital stay lengths and mortality rates. Increasing resistance to antibiotics makes the treatment of these infections more difficult. Novel antimicrobial compounds derived from natural sources may be useful for addressing antiobiotic resistance. The objective of this study is to determine the chemical composition and antimicrobial activities of essential oils from Myrtus communis L. (Myrtaceae) leaves against pathogens causing nosocomial infections. The chemical composition of essential oil from M. communis leaves was analysed by gas chromatography-mass spectrometry (GC-MS). The antimicrobial activity of the essential oil against bacteria and fungi was evaluated by broth micro-dilution as per the Clinical and Laboratory Standards Institute (CLSI) methods. GC-MS analysis revealed that the major constituents of the essential oil were α-pinene (39.2 %), 1,8-cineole (22.0 %), and linalool (18.4 %). The essential oil exhibited antimicrobial activity against all Gram positive and Gram negative bacteria with MICs in the range of 0.5-32 μL/mL and 8-64 μL/mL, respectively. MICs for the tested clinical and standard fungi were in the range of 0.03-16 μL/mL. The essential oil exhibited strong antibacterial and antifungal activities against all the causative agents of nosocomial infections examined, particularly against strains with antibiotic resistance. The essential oil from M. communis leaves is a potential source of novel antimicrobial agents for the treatment of nosocomial infections.

“…Its presence has been reported in the myrtle essential oils of different countries such as Portugal (9), Tunisia (10), Morocco (15), Spain (19), Croatia (20), Albania (22) and Turkey (23). The absence of myrtenyl acetate has been reported in countries such as Greece (10), Italy (14), Tunisia (16,17), Croatia (20) and France (24). This study represents the first analysis of the essential oils of Algerian Myrtus communis.…”

“…According to the literature, myrtle essential oils are endowed with antibacterial, antifungal, antioxidant and antimutagenic properties (4)(5)(6)(7)(8). The chemical composition of myrtle essential oil has been extensively studied in different countries (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). In previous studies, myrtle oils were separated into two groups: the first group is characterized by a high content of myrtenyl acetate and a low content of a-pinene; the second group is characterized by the lack of myrtenyl acetate and a high content of a-pinene and 1,8-cineole as the main constituents (25).…”

Myrtus communis L. essential oils were obtained by hydrodistillation, and the yields were 0.3% (w/w) and 0.1% for leaves and berries, respectively. Using gas chromatography (GC) and gas chromatography/mass spectometry (GC/MS), 25 components were identified in berry oil representing 89.5% of the oil composition. Linalool was the major compound in berry oil (36.2%) followed by estragole (18.4%) and 1,8-cineole (11.4%). Leaf oil was composed of 28 compounds representing 95.4% of the total composition of the oil. a-pinene was the major constituent of leaf oil at a concentration of (46.9%), followed by 1,8-cineole (25.2%). The two Algerian oils were characterized by the lack of myrtenyl acetate.

“…Leaves and fruits were used against respiratory and urinary diseases [5,9]. Essential oil extracted from these organs is rich in α-pinene and 1,8-cineole [33,47]. The demand for this plant is increasing in pharmaceutic, perfumery and food industries [34,35].…”

Variabilité génétique des populations tunisiennes de Myrtus communis L. (Myrtaceae) estimée par des marqueurs isoenzymatiques et moléculaires (RAPD)

-The genetic variation of six Tunisian Myrtus communis L. (Myrtaceae) populations was assessed using nine isozymes coding for 17 putative loci and 79 RAPD markers, amplified by five decamer random primers. The analysed populations belonged to three bioclimatic zones (lower humid, sub-humid and upper semi-arid). A high genetic diversity within populations was detected both by isozymes and RAPDs. The level of variation differed according to bioclimate. Populations collected from sub-humid bioclimate showed more polymorphism than those grown in the upper semi-arid zone. For all populations, the genetic diversity revealed by RAPDs was more pronounced than that detected with isozymes. A high differentiation among populations related to bioclimate and geographic distance was revealed by both methods. Population's structure based on RAPD markers was more concordant with bioclimatic zones in comparison with isozymes. Differentiation between ecological groups was higher than that revealed within groups. Conservation programs should take into account the level of genetic diversity within population revealed by the two complementary classes of markers according to bioclimate. Une diversité génétique intrapopulation importante a été détectée. Le niveau de polymorphisme varie selon le bioclimat. Les populations du sub-humide sont plus polymorphes. Pour l'ensemble des populations, la diversité génétique révélée par les RAPDs est plus importante que celle détectée par les isozymes. Une forte différenciation entre les populations, selon le bioclimat et l'éloignement géographique, a été révélée par les deux méthodes. La structuration des populations selon les marqueurs RAPD concorde mieux avec le bioclimat. La différenciation entre les populations appartenant à des groupes écologiques différents est plus importante que celle entre populations d'un même groupe. Les programmes de conservation de l'espèce doivent tenir compte aussi bien du degré de la diversité génétique intrapopulation révélé par les deux types de marqueurs que du bioclimat.
