    ABSTRACT: The antifungal properties of evaporation residue of essential oils (EOs) derived from the needles of the three Japanese planted conifer species Cryptomeria japonica, Pinus thunbergii and Thujopsis dolabrata var. hondae were evaluated. Open system mild heat treatments (MHTs) enhanced the volatilities of the EOs, leading to changes in their chemical composition. The activities of all EOs increased according to the monoterpene hydrocarbons evaporated, and then gradually decreased with the component degradation. These results indicated that the terpenoid components in lower volatile phase together with a variety of components could be responsible for the antifungal activities of these EOs. Further investigation also showed that the C. japonica EO showed the highest antifungal potential of the three EOs because it contained the major sesquiterpene alcohol elemol. This study represents the first reported time course investigation of changes in the chemical composition and antifungal properties of conifer needle EOs based on their volatility.

    ABSTRACT: The seasonal variation of essential oil composition of aerial parts and roots of Artemisia absinthium L. has been investigated. It was obtained from individuals growing wild in Teruel (Spain) by means of hydrodistillation (aerial parts) or simultaneous distillation extraction (roots), and analyzed by GC/MS and GC/FID. Results showed a predominance of oxygenated monoterpenes (81.4-89.1%) in aerial parts; mainly (Z)-epoxyocimene (49.3-71.5%), (Z)-chrysanthemyl acetate (7.6-18%) and linalool (0.7-10.4%). In spite of the high intrapopulational variability, significant variations were observed for these three compounds. Root essential oil composition showed a high amount of hydrocarbon monoterpenes (43.8-55.1%) and monoterpenic esters (36.6-41.5%) with a noticeable seasonal stability except for some allelopathic oxygenated monoterpenes. As A. absinthium is a typical invasive species, knowing the seasonal variations of these compounds may be a first step to study their release in soil as a source for natural herbicides.

    ABSTRACT: Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0-54.4%), γ-terpinene (9.8-30.5%), ρ-cymene (5.2-18.7%), α-terpinene (2.7-5.7%), carvacrol (0.3-8.3%), terpinen-4-ol (0.5-9.4%) and trans-sabinene hydrate (0.0-12.8%). All the biotypes analyzed were identified as thymol-chemotype. Statistical analysis shows that essential oil yields are mostly affected by weather/climate and topographic characteristics of the collection sites.

    ABSTRACT: A literature-based survey of black cumin (Nigella sativa L.) essential oil composition and properties was reviewed. Non-traditional oilseeds attracted great interest because their components have unique properties and may augment the supply of novel products. Analysis of N. sativa essential oil using GC techniques resulted in the identification of many bioactive phytochemicals representing ca. 85% of the total compounds. The main compounds include p-cymene, thymoquinone, α-thujene, longifolene, β-pinene, α-pinene and carvacrol. N. sativa oil exhibited various biological properties including antifungal, antibacterial and antioxidant potentials. N. sativa oil showed complete inhibition zones against Gram-negative and Gram-positive bacteria including Penicillium citrinum Bacillus cereus, Bacillus subtilis, Staphylococcus aureus and Pseudomonas aeruginosa. The oil showed higher antioxidant potential in comparison with synthetic antioxidants in a rapeseed oil model system. The oil exhibited also stronger antiradical activity against DPPH radical. The diversity of food and non-food applications to which N. sativa oil can be put, gives this oil industrial and commercial importance.

    ABSTRACT: Essential oils obtained by steam distillation from Swinglea glutinosa (Blanco) Merr. fruit peel or leaves were analyzed by gas chromatography with flame ionization and mass spectrometry detection systems. A total of sixty-seven compounds were found, sixty-four of which were common to both oils, although present in different relative amounts. The main component of the essential oils obtained from S. glutinosa fruit peel or leaves was trans-nerolidol (19.1% and 28.4%, respectively). Sesquiterpene hydrocarbons (50%) and their oxygenated analogues (35%) were the most abundant compound types in the leaf oil. Monoterpene hydrocarbons (51%) were the principal compound family found in the oil obtained from fruit peels.

    ABSTRACT: Seeds of Psoralea corylifolia L. were irradiated with different doses of gamma rays; 2.5, 5, 10, 15 and 20 kGy from a cobalt source a at dose rate of 1.65 kGy/hour. The stimulatory effects of gamma irradiation at 10 kGy were evident for biochemical and elemental parameters at the flowering stage and thereafter declined. Nitrogen was found to be maximum in leaves and sulfur in roots at the flowering stage of seedlings grown from seeds exposed to 10 kGy. Sulfur content was found to be most sensitive to gamma irradiation doses resulting in a maximum decline in stems (89.10%), leaves (65.79%) and roots (57.07%) with 20 kGy, respectively. Amino acids exhibited a similar percent decline (52.79%) at the pre-flowering stage in plants raised from seeds irradiated with 20 kGy. Using gas chromatography–mass spectrometry (GC–MS) and solid-phase particle microextraction (SPME) analysis, a remarkable percent increment was confirmed in tricyclene, α-pinene, β-myrcene, camphene, caryophyllene, β-gurgenene, n-nonanal, β-(E)-ocimene, (Z)-3-hexene-ol and germacrene D in plants raised from seeds exposed to 20 kGy. Maximum oil content (1.60%) was found in seeds irradiated with 20 kGy and minimum oil content was found in control seeds (0.89%). The study demonstrates the inverse response between primary and secondary metabolites in terms of enhancement in essential oil yield, as well as concentration of antioxidant components at 15 and 20 kGy.

    ABSTRACT: The chemical profile of the essential oil obtained from leaves and inflorescences of Psidium myrsinites DC. (Myrtaceae) growing wildly in the Brazilian Cerrado was analyzed by GC/FID and CG/MS. The essential oil had a slimy and translucent appearance. The oil yield was 0.1% and the main components were oxygenated sesquiterpenes (68.2%) and non-oxygenated sesquiterpenes (18.3%). Caryophyllene oxide (26.1%), humulene epoxide II (8.8%), β-caryophyllene (7.4%) and α-caryophyllene (5.4%) were the major compounds. It is worth to notice that the most abundant substances have very close structures. The oil yield and composition was very similar to other species belonging to the same genus.

    ABSTRACT: The essential oils from six chemo-types of Zataria multiflora (ZMO) was obtained and examined for chemical composition and antioxidant, antimicrobial and cytotoxic activities. Chemical analysis of ZMO was done by using gas chromatography and mass spectrometry (GC/MS). The antioxidant capacity of ZMO was examined through measuring ABTS, H2O2, nitrite and malondialdehyde (MDA) scavenging effects. The antibacterial activity toward Salmonella typhimurium, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Aspergillus niger and Candida albicans were tested by minimum inhibitory concentration (MIC) determination. The cytotoxic effect of ZMO was tested on the human nasopharyngeal cancer cell line (KB), liver hepatocellular carcinoma cell line (HepG-2) and epithelial breast cancer cell line (MCF-7). The main components of ZMO were carvacrol (4-57%), thymol (1-45%), p-cymene (4-20%), γ-terpinene (1-38%) and linalool (1-33%). ZMO exhibited good antioxidant activity against ABTS, H2O2, nitrite and MDA at concentrations less than 10 μg/mL. ZMO showed good cytotoxic activity against tested bacteria and fungi, and tumor cell line at concentrations less than 10 and 20 μg/mL, respectively. Thymol-rich ZMO exhibited stronger antioxidant activity, while carvacrol-rich ZMO exhibited stronger antibacterial, antifungal and antitumor activities.

    ABSTRACT: The composition of the essential oils of six individual plants of Artemisia herba-alba Asso, growing wild in six different locations from southern Algeria, were investigated by capillary gas chromatography (GC) and GC/mass spectrometry (GC/MS) in combination with retention indices. Accounting for 76.3-97.2% of the oils, 132 constituents were identified, predominantly α-thujone (trace-47.1%), camphor (5.6-30.0%), chrysanthenone (trace-13.5%), β-thujone (trace-9.2%), 1,8-cineole (4.1-11.4%), cis-jasmone (0.8-12.1%) and davanone (trace-34.0.%). Regarding the α- and β-thujone toxicity and the extensive use of A. herba-alba as an aromatic and medicinal plant in folk medicine, we report here, with previous investigations, the thujone content of forty individual plants of A. herba-alba growing wild in sixteen different locations from the high table-lands, steppes and Sahara desert of Algeria. The available data indicate a high degree of variability in the percentage of the two constituents. Large amounts were present in essential oils of Ghardaia (88.9%), Ain-Sefra (59.0%), Laghouat (57.7%) and Sebdou (55.7%).

    ABSTRACT: Cold-pressed citrus essential oils contain variable amounts of oxygen heterocyclic compounds highly characteristic of each species. Their distribution has been defined by high-performance liquid chromatography (HPLC) analysis with an average time of about 45 minutes. Here are two methods proposed, applying the latest generation HPLC columns based on the fused-core technology. The first method allows the complete resolution of thirty-eight components for a rugged and validated quantitative determination of the oxygen heterocyclic compounds in cold pressed lemon, lime, bergamot grapefruit, sweet orange, bitter orange and mandarin oils, in 10 minutes of total analysis time. The second method is a compromise between chromatographic resolution and analysis time and allows a fingerprinting of each of the abovementioned oils to be obtained, useful for unveiling possible contaminations and frauds in about 3 minutes. This last method can be applied in routine analysis to save time and solvent. The components are sufficiently separated in all the citrus cold pressed oils, permitting detailed profiles of each oil to be acquired and possible contaminations and frauds to be detected.

    ABSTRACT: The hydro-distilled essential oils obtained from the different organs (roots, leaves, stalks, inflorescences and fruits) of Kelussia odoratissima, an endemic medicinal plant of Iran, were analyzed by gas chromatography-flame ionization detector (GC-FID) and GC-mass spectrometry (GC-MS) to determine their chemical composition. The essential oil content (w/w%) was in the order of: fruit (1.4%) > root (1.05%) > stalk (0.37%) > leaf (0.27%) > inflorescence (0.2%). The total number of compounds identified and quantified were thirty-two in roots, thirty-one in stalks, twenty-one in leaves, twenty-one in inflorescences and six in fruits, representing 99.5%, 99.2%, 98.2%, 98.1% and 99.7% of the total oil, respectively. The phthalide (Z)-ligustilide (54.0-86.0%) and (2E)-decen-1-ol (2.0-12.3%) were the major compounds in all plant organs. These results suggest that the five studied organs of K. odoratissima are potentially good sources of phthalides, which are known for their anti-inflammatory, anti-tumor and insecticidal properties. This is the first report on the essential oil composition profile in the full range of organs of this species.

    ABSTRACT: The effect of five drying methods on the essential oil content and composition of Rosa foetida Herrm. was studied for incorporation into a post-harvesting program for medicinal and perfumery industries. The drying methods tested were sun drying (SD), closed shade drying (CSD), oven drying at 40°C (OD40) and 60°C (OD60) and microwave drying (MD). The essential oils from fresh and dried samples were isolated by hydrodistillation and analyzed by a gas chromatography-flame ionization detector (GC-FID) and GC-mass spectrometry (GC-MS). The drying method had a significant effect on the essential oil content (w/w%) in the order of: CSD (0.28%) > SD (0.20%) > OD40 (0.18%) > OD60 (0.14%) > MD (0.05%). In total, twenty-three, thirteen, eight, twelve, ten and twelve constituents were identified and quantified in fresh, CSD, SD, OD40, OD60 and MD samples, representing 93.4%, 97.5%, 97.3%, 97.4%, 98.0% and 96.7% of the total oil, respectively. The major components of all samples were n-nonadecane (25.8-56.4%), n-heneicosane (16.7-24.4%), 1-hexadecanol (14.5-19.7%), n-tetradecanol (1.5-6.8%) and Z-octadecadienal (1.0-5.2%). Our results showed that the drying method not only had an effect on the number of chemical components, but also significantly influenced the proportion of various constituents.
