“…The negative control did not inhibit the growth of the bacteria tested and the positive control showed strong inhibition against all employed bacterial strains. Almost similar antimicrobial results were obtained from both essential oils of lemon samples by other reported results (Nicolosi et al, 2000;Reichling et al, 2009;Kirbaslar et al, 2006;Ahmad et al, 2006).…”

a b s t r a c tThe aim of this work to isolate and identify two essential oils by hydro distillation method from two imported lemon fruits samples collected from local supermarket and evaluate their antimicrobial activity against pathogenic bacteria through disc diffusion method. The essential oil was obtained from Turkish and Indian lemon fruits samples by hydro distillation method using Clevenger type apparatus. Both isolated essential oils were identified by GCeMS and determine their in vitro antimicrobial activity against pathogenic bacteria through agar gel method. Twenty two bioactive ingredients with different percentage were identified based on GC retention time from Turkish and Indian lemon collected from local supermarket. The predominant bioactive ingredients with high percentage in Turkish essential oil were DL-limonene (78.92%), a-pinene (5.08%), L-a-terpineol (4.61%), b-myrcene (1.75%), b-pinene (1.47%) and b-linalool (0.95%) and in Indian essential oil were DL-limonene (53.57%), L-a-terpineol (15.15%), b-pinene (7.44%), a-terpinolene (4.33%), terpinen-4-ol (3.55%), cymene (2.88%) and E-citral (2.38%) respectively. Both isolated essential oils by hydro distillation were used for the study of antimicrobial activity against four pathogenic bacterial strains such as Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa) and Proteus vulgaris (Pseudomonas vulgaris). Almost all bacterial strains did not give any activity against the employed essential oils at different concentrations. Therefore, the obtained results show that both essential oils could be needed further extensive biological study and their mechanism of action.

“…2 and Table 2). The major chemical ingredients in the Turkish essential oil after chemical analysis results was reported by Kirbaslar et al (2006) who showed that limonene was the major constituents. Whereas, in our result the main chemical ingredient identified in Turkish oil was same but different percentage.…”

“…We used this approach successfully before to analyze the contents of essential oil-accumulating glandular trichomes (Rios-Estepa et al, 2008). The main volatile terpenoids in the microcapillary-collected oil were (+)-limonene (93%-94%), myrcene (3%), and sabinene (0.7%-2.1%; Table I), which is in agreement with published data on the most abundant volatile constituents in cold-pressed oils (Kirbaslar et al, 2006;Espina et al, 2010). Sesquiterpenes occurred as minor components (Table I), which is also in accordance with previous reports (Flamini and Cioni, 2010).…”

Epithelial cells (ECs) lining the secretory cavities of Citrus peel have been hypothesized to be responsible for the synthesis of essential oil, but direct evidence for such a role is currently sparse. We used laser-capture microdissection and pressure catapulting to isolate ECs and parenchyma cells (as controls not synthesizing oil) from the peel of young grapefruit (Citrus × paradisi ‘Duncan’), isolated RNA, and evaluated transcript patterns based on oligonucleotide microarrays. A Gene Ontology analysis of these data sets indicated an enrichment of genes involved in the biosynthesis of volatile terpenoids and nonvolatile phenylpropanoids in ECs (when compared with parenchyma cells), thus indicating a significant metabolic specialization in this cell type. The gene expression patterns in ECs were consistent with the accumulation of the major essential oil constituents (monoterpenes, prenylated coumarins, and polymethoxylated flavonoids). Morphometric analyses demonstrated that secretory cavities are formed early during fruit development, whereas the expansion of cavities, and thus oil accumulation, correlates with later stages of fruit expansion. Our studies have laid the methodological and experimental groundwork for a vastly improved knowledge of the as yet poorly understood processes controlling essential oil biosynthesis in Citrus peel.

“…In addition, trace amounts of geranyl propionate, undecanal, germacrene D, bicyclogermacrene and (E,E)-α-farnesene as well as 0.1% of α-bisabolol were determined in the samples here analyzed, which were not reported in Turkish CP lemon oil previously (35). …”

“…The composition of Italian lemon oil has also been widely studied (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27). Some researchers studied French, Japanese, Tunisian, Greek, Uruguayan, Venezuelan, Colombian and Turkish lemon oil (4,(28)(29)(30)(31)(32)(33)(34)(35).…”

Kıbrıs lemon (Citrus limon (L.) Burm. f.) peel was extracted by supercritical CO 2 extraction (SFE), cold pressing (CP) and hydrodistillation (HD) methods. SFE, CP and HD methods have been compared and evaluated for their effectiveness in the separation of extract from fresh lemon peels. The chemical compositions of the three different extract samples were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Forty-four components were fully characterized by mass spectra and linear retention indices. The lemon extracts showed a high content of limonene (71.81%, 70.36% and 72.48%) with γ-terpinene (8.72%, 8.91% and 8.88%), β-pinene (6.61%, 6.72% and 6.60%), myrcene (1.55%, 1.59% and 1.73%), sabinene (1.21%, 1.48% and 1.09%), α-pinene (0.98%, 1.27% and 0.98%) and p-cimene (0.87%, 1.23% and 0.87%) being the major monoterpene hydrocarbons in the SFE, CP and HD methods, respectively. The principal sesquiterpene hydrocarbon was β-bisabolene (1.42%, 1.41% and 1.22%) in the SFE, CP and HD extracts, respectively. Neryl acetate and geranial were the main oxygenated compounds (1.25%, 1.28% and 1.21%) and (1.13%, 0.97% and 0.99%), in the SFE, CP and HD extracts, respectively. The composition of lemon extract has been split into six classes (monoterpene hydrocarbons, sesquiterpene hydrocarbons, carbonyl compounds, alcohols, esters and oxides). It was noted that there were significant differences in the carbonyl compounds, alcohol and ester classes in the SFE, CP and HD extracts.
