WOS: 000455644400004, This study was conducted on the antibacterial, antimycobacterial and antifungal activities of various extracts (petroleum ether (PE), chloroform (CHCl3) and ethanol (EtOH) extracts; infusion and decoction) and essential oil from the aerial parts of S. cassia Sam. ex Rech.f. and the chemical composition of the most active samples. The antibacterial activity was determined against Bacillus subtilis, Staphylococcus aureus, methicillin resistant Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Klebsiella pneumoniae, Proteus mirabilis and Escherichia coli. The antimycobacterial activity was analyzed against five different Mycobacterium tuberculosis and the antifungal activity was compared with two dermotophytes and three Candida species. The composition of EO was analyzed by GC-FID and GC-MS. The EO had a very good activity against B. subtilis (0.3 mu L/mL) and good activity against S. aureus, methicillin resistant S. aureus (MRSA) and E. faecalis (0.6 mu L/mL). All extracts were active in the antimycobacterial and antifungal tests (MICs=50-400 mu g/mL). The EO was the most active samples against all Mycobacterium strains, dermatophytes and Candida species (MICs=0.1-6.25 mu L/mL). Because of the high activity of EO, its composition was analyzed, and the major compound was found caryophyllene oxide (22.3%), which was also found the major components of the essential oils from other antimicrobial plants such as Salvia trichoclada Benth., Scientific and Technological Research Council of Turkey [114S734], The parts of the antibacterial and antimycobacterial assays in this present work was supported by the Scientific and Technological Research Council of Turkey.

WOS: 000467873500017, Ferulago species have been utilized since ancient times as antihelmentic, digestive, sedative and aphrodisiac, along with in salads or as a seasoning in view of their special odours. F. pachyloba (Fenzl) Boiss., F. trachycarpa Boiss. and F. bracteata Boiss. & Hausskn. species were investigated for their chemical compositions of essential oils and their antimicrobial activities. Antimicrobial activities of essential oils were performed via microbroth-dilution and TLC bioautography methods. GC and GC/MS were utilized to analyse the essential oils. Primary components of aerial parts, flowers, roots and fruits of F. pachyloba were found as, sabinene (16.0 %), (Z)-beta-ocimene (15.1 %); sabinene (25.8 %), (Z)-beta-ocimene (27.5 %); (E)-2-decenal (14.3 %); bicyclogermacrene (11.1 %), respectively. Primary components of aerial parts, roots and fruits of F. trachycarpa were found as, (Z)-beta-ocimene (13.8 %), spathulenol (25.0 %); (E)-2-decenal (11.9 %); spathulenol (32.8 %), bicyclogermacrene (23.0 %). Primary components of aerial parts, flowers and roots of F. bracteata were found as, 7-methoxy-6-(3-methyl-2-butenyl)-coumarin (86.7 %); beta-pinene (12.1 %), beta-phellandrene (22.8 %); (E)-2- decenal (13.9 %), hexadecanoic acid (40.4 %). Essential oils were particularly more effective against Staphylococcus aureus, with MIC values of between 0.39 and 6.25 g/mL, respectively. They did not give significant inhibition against Pseudomonas aeruginosa by TLC bioautography assay. In contrast, they had active components against S. aureus and showed significant inhibition. The antimicrobial activities against these microorganisms from these species may be attributed to the presence of the main components in the essential oils., Scientific and Technological Research Council of Turkey [TUBITAK 115S009], This work was supported by the The Scientific and Technological Research Council of Turkey (TUBITAK 115S009).

Thymus L. of the Lamiaceae with 220 ssp. is concentrated in the Mediterranean region. Thymus species are well known as “Kekik” in Turkish and are used as herbal tea and spices, according to recent records, the genus is represented with 40 ssp. where 17 species are endemic to Turkey. The study material Thymus pallasicus is one of the endemic species for Turkey, from which the essential oil was obtained from the air dried aerial parts by hydro distillation subsequently analyzed by GC-FID and GC-MS, respectively. The main component was identified as thymol (55.5 %) along with the monoterpenes p-cymene (19.9 %), ?-terpinene (7.2%), carvacrol (5.0 %), and 1,8-cineole (1.4%). The essential oil was also evaluated for its anticandidal activity against five different standard human pathogenic strains, according to a modified in vitro CSLI micro dilution method. The minimum inhibitory activity of the essential oil was 250-500 microgram/mL against the tested Candida sp. suggesting rather weak inhibitory activity when compared to the standard antifungal fluconazole (0.5-16 microgram/mL). As Thymus species are known for their antimicrobial activities it is suggested that other clinical and pathogenic strains should be further evaluated. © 2019, Badebio Biotechnololgy Ltd.

As part of our continuing investigation for interesting biological activities of native medicinal plants, thirty-nine plants, obtained from diverse areas in Saudi Arabia and Yemen, were screened for insecticidal activity against yellow fever mosquito Aedes aegypti (L.). Out of the 57 organic extracts, Saussurea lappa, Ocimum tenuiflorum, Taraxacum officinale, Nigella sativa, and Hyssopus officinalis exhibited over 80% mortality against adult female Ae. aegypti at 5 µg/mosquito. In the larvicidal bioassay, the petroleum ether extract of Aloe perryi flowers showed 100% mortality at 31.25 ppm against 1st instar Ae. aegypti larvae. The ethanol extract of Saussurea lappa roots was the second most active displaying 100% mortality at 125 and 62.5 ppm. Polar active extracts were processed using LC-MS/MS to identify bioactive compounds. The apolar A. perryi flower extract was analyzed by headspace SPME-GC/MS analysis. Careful examination of the mass spectra and detailed interpretation of the fragmentation pattern allowed the identification of various biologically active secondary metabolites. Some compounds such as caffeic and quinic acid and their glycosides were detected in most of the analyzed fractions. Additionally, luteolin, luteolin glucoside, luteolin glucuronide and diglucuronide were also identified as bioactive compounds in several HPLC fractions. The volatile ketone, 6-methyl-5-hepten-2-one was identified from A. perryi petroleum ether fraction as a major compound, U.S. Department of Defense, DOD Deanship of Scientific Research, King Saud University, The authors extend their appreciation to the Deanship of Scientific Research at King Saud University for funding this work through research group No. RG-1437-021 .

Background and Objectives: PIN1 is overexpressed in several human cancers, including prostate cancer, breast cancer, and oral squamous carcinomas. Juglone (J), derived from walnut, was reported to selectively inhibit PIN1 by modifying its sulfhydryl groups. In this study, the potential effects of juglone, also known as PIN1 inhibitor, on oral cancer and carcinogenesis were investigated at the molecular level. Materials and Methods: 4-Nitroquinoline N-oxide (4-NQO) was used to create an oral cancer model in animals. Wistar rats were divided into five groups: Control, NQO, Juglone, NQO+J, and NQO+J*. The control group received the basal diet and tap water throughout the experiment. The NQO group received 4-NQO for 8 weeks in drinking water only. The Juglone group was administered intraperitoneally in a juglone solution for 10 weeks (1 mg/kg/day). The NQO+J group received 4-NQO in drinking water for 8 weeks, starting 1 week after the cessation of 4-NQO treatment. They were then administered intraperitoneally in a juglone solution for 10 weeks. (1 mg/kg/day). NQO+J* group: received 4 NQO for 8 weeks in drinking water and administered intraperitoneally in a juglone solution for 10 weeks (1 mg/kg/day). They were sacrificed at the end of the 22-week experimental period. The tongue tissues of the rats were isolated after the experiment, morphological changes were investigated by histological examinations, and the molecular apoptotic process was investigated by rt-qPCR and western blot. Results: Histological results indicate that tumors are formed in the tongue tissue with 4-NQO, and juglone treatment largely corrects the epithelial changes that developed with 4-NQO. It has been determined that apoptotic factors p53, Bax, and caspases are induced by the effect of juglone, while antiapoptotic factors such as Bcl-2 are suppressed. However, it was observed that the positive effects were more pronounced in rats given juglone together with 4-NQO. Conclusions: The use of PIN1 inhibitors such as juglone in place of existing therapeutic approaches might be a promising and novel approach to the preservation and treatment of oral cancer and carcinogenesis. However, further research is required to investigate the practical application of such inhibitors.

Essential oils obtained by hydrodistillation from the aerial parts and fruits of five taxa of genus Grammosciadium DC., belonging to subgenus Grammosciadium (G. confertum Hub.-Mor. & Lamond, G. cornutum (Nábělek) C.C.Towns., G. macrodon Boiss. subsp. macrodon, G. macrodon Boiss. subsp. nezaketae B.Bani and G.daucoides DC. ), collected from different locations in Turkey, were simultaneously analyzed by GC and GC/MS systems. 124 components representing 71.1-99.8% of the total contents were identified in the oils. Oil samples from fruits and aerial parts of the plants showed different chemical profiles with regard to species. We have herein demonstrated that the chemical composition of essential oil samples from G. cornutum , G. macrodon subsp. macrodon , G. macrodon subsp. nezaketae (an endemic subspecies) , and G. confertum (an endemic species) growing in Turkey was determined for the first time. Hexadecanoic acid (13.3-21.2% and 48.1-59.8%) was the main component of the samples of G. cornutum and G. confertum, respectively, while caryophyllene oxide (13.1-29.2%) was the major constituent in the samples of G. macrodon subsp. nezaketae and G. macrodon subsp. macrodon as well as γ-terpinene (61.9%) and carvacrol (68.9%) in G. daucoides samples. In addition, pentacosane can be considered a chemotaxonomic marker for the essential oil of G. macrodon subsp. macrodon.

Lathyrus species including L. ochrus and L. sativus are known for their food, feed and horticultural uses. Despite their widespread uses and cultivation, there is limited information on their chemistry. Previously, only the essential oil composition of L. rotundifolius, L. vernus and volatiles of L. odoratus have been reported. In the present research, volatiles of seven Lathyrus L. species, namely, L. aphaca, L. ochrus, L. cicera, L. sativus, L. gorgonei, L. saxatilis and L. blepharicarpos var. cyprius were analyzed by SPME GC-MS for the first time. Plant materials were collected from five different locations in Cyprus (February-March 2012). The main components of L. aphaca volatiles from four locations were yomogi alcohol 26.1-16.5%, camphor 21.6-10.1%, tetradecane 14.3-0%; L. cicera from five locations were yomogi alcohol 20.3-3.0%, camphor 18.7-2.0%; L. gorgonei from two locations were yomogi alcohol 24.5-13.1%, camphor 17.1-9.0% and L. sativus was yomogi alcohol 11.4%, camphor 9.0%. Yomogi alcohol was not present as the major compound in L. ochrus (2-methyl butanoic acid 7.2%), L. saxatilis (hexanal 7.7%) and L. blepharicarpos var. cyprius ((Z)-3-hexenal 8.6%) volatiles. The volatiles of the Lathyrus species were also compared with each other quantitative and qualitatively using AHC analysis to find out differences among the species. The irregular monoterpene yomogi alcohol is reported from the Lathyrus and the Leguminosae family for the first time. The existence of yomogi alcohol in Lathyrus volatiles points out that the irregular monoterpenes are not restricted solely to Asteraceae family.

There is only a couple of reports indicating essential oil composition of Asphodelus species in the literature. However, from the members of this genus many non-volatile secondary metabolites were isolated. In Cyprus, Asphodelus aestivus Brot. can be found abundantly in all regions of the island. This plant has various ethnobotanical uses in Cyprus. There is no report on the volatiles nor the essential oil composition of A. aestivus. The smell of A. aestivus flowers resembles that of a cat pee which caught our attention. Therefore, we have carried out GC, GC/MS analysis of the essential oil (yield: 0.01 v/w) obtained from Asphodelus aestivus flowers. Seventeen compounds were identified in the essential oil comprising 96.2% of the oil. The major components of the essential oil were hexadecanoic acid 35.6%, pentacosane 17.4%, tricosane 13.4% and heptacosane 8.4%. In our results, we expected to see sulfur containing cat pee odorants due to the odor of the flower whereas high amounts of n-alkanes, saturated fatty acids and minor amounts of acyclic diterpenes were observed.

The Mediterranean fruit fly or medfly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most economically important invasive pests worldwide, with over 300 known hosts. Essential oils have great promise for application in integrated pest management, where they function as natural repellents, attractants, and toxicants with a reduced impact on the environment. In this study, we evaluated essential oil from aerial parts of the African ginger bush, Tetradenia riparia (Hochst.) Codd (Lamiaceae), as a potential new attractant for male C. capitata. Tetradenia riparia essential oil (TREO) was analyzed by gas chromatography (GC)-flame ionization detection and GC-mass spectrometry (GC-MS). The primary compounds identified were fenchone (15%), δ-cadinene (11%), 14-hydroxy-β-caryophyllene (8%), and tau-cadinol (7%). In short-range laboratory bioassays with sterile male medflies, TREO exhibited attractancy comparable to that observed with a positive control, essential oil from tea tree ( Melaleuca alternifolia (Maiden and Betche) Cheel.). This study provides the first report of C. capitata behavioral response to TREO. Further research is needed, particularly with the 2 enantiomers of fenchone, to determine the chemical constituents responsible for the attraction of C. capitata.

The air-dried aerial parts of Phlomis russeliana (Sims) Lag. Ex Benth. was extracted by methanol and fractionated by n-hexane, dichloromethane, and ethyl acetate, respectively. The wound healing properties of P. russeliana extract gel was evaluated using the in vivo excisional wound model using Balb-c mice. Initially, the P. russeliana methanol extract showed LOX inhibitory activity at IC50 = 23.2 µ, g/mL, whereas the DPPH&bull, assay showed IC50 = 0.89 mg/mL, and the ABTS&bull, assay showed IC50 = 0.99 mg/mL, respectively. In addition, a remarkable anti-inflammatory activity was observed in the cell culture assay. Thereafter, activity-guided fractionation was performed by LOX enzyme inhibition assays, and the structures of the two most active fractions were revealed by both GC&ndash, FID and GC/MS analyses, simultaneously. Phytol and 1-heptadecanoic acid were characterized as the active constituents. Moreover, the P. russeliana extract gel formulation was applied for in vivo tests, where the new gel formulation supported the in vitro anti-inflammatory activity findings. As a conclusion, this experimental results support the wound healing evidence based on the ethnobotanical application of Phlomis species with further potential.

The main aim of the present study was to investigate the antibacterial effect of the commercial Pharma Grade S. officinalis subsp. lavandulifolia (Lamiaceae) essential oil against the skin pathogen Staphylococcus aureus. The chemical composition of the essential oil was confirmed by GC and GC/MS, simultaneously. Camphor (30.5%), 1,8-cineole (24.8%), ?-pinene (6.5%), linalool (4.0%) and linalyl acetate (3.5%) were found as major components. The bioactivity of the essential oil and its main compounds were tested using the in vitro microdilution technique. Minimum inhibitory concentration (MIC) values of ?-pinene, essential oil, camphor, linalool and linalyl acetate were in the range of 2.5-10 mg/mL, respectively. The results showed that the tested pathogen was only moderately susceptible against the essential oil and its main compounds when compared with standard antibiotics. In addition, the in vitro antioxidant activity was evaluated using the radical scavenging activity mediated by 1,1-diphenyl-2-picrylhydrazyl (DPPH). The activity range was found more than 30 mg/mL for all tested oil samples, compared with the standard. The results suggested that the oil and its major constituents represent antimicrobial activity supporting its antiseptic use in folk medicinal use, Anadolu Üniversitesi, This study was financially supported by Anadolu University ?

WOS: 000434745000032, In this present study, commercial Pharmacopeia (PhEur) grade chamomile essential oil (Mairicariae aetheroleurn) was combined with different antimicrobial agents including ampicillin sodium, cefuroxime acetyl, tetracycline hydrochloride, fluconazole and nystatin. All combinations were evaluated in vitro against pathogenic standard and clinical resistant Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacterial isolates as well as against Candida albicans for their broad antimicrobial effectiveness. Furthermore, the essential oil was fractioned by column chromatography using n-hexane, diethyl ether, dichloromethane and methanol, respectively. Additionally, all fractions of essential oil were tested in combinations for their minimum inhibitory concentrations (MIC) as well as for their fractional inhibitory concentrations (FIC) against the resistant microbial pathogens. Antimicrobial activities were evaluated by microdilution method and antimicrobial interactions were assayed using the checkerboard method. Cytotoxicity of compounds were evaluated using Cytotox-XTT-1 1:rameter Kit in WS1 cells and Aliivibrio fischeri bioluminescence toxicity assay. The analyses proved that alpha-bisabolol oxide A (47.7%), (E)-beta-famesene (21.5%), alpha-bisabolol oxide B (6.2%), alpha-bisabolone oxide A (5.8%), chamazulene (4.1%) and alpha-bisabolol (2.2%), respectively were the major compounds and in compliance with PhEur. The essential oil combination of fluconazole and nystatin showed "synergic and additive inhibitory effects" against the clinical Candida strain. According to the IC50 values obtained, the inhibitory concentrations of combinations against the clinical Candida strain can be considered to be selective when compared with its effect on WS1 cells. Additionally, the essential oil combination of fluconazole and nystatin showed low toxicity against A. fischeri., Anadolu University Research Fund [BAP-13015005]; Tubitak SBAG [1135250], This work is part of the PhD project of Gamze Goger and was supported by the Anadolu University Research Fund (Project no: BAP-13015005) and Tubitak SBAG 1135250.

WOS: 000349430000006, Dengue fever is a mosquito-borne disease transmitted by Aedes aegypti producing high rates of human morbidity and mortality. In order to find new and effective compounds against A. aegypti with low mammalian and less environmental toxic products, green and red Purilla frutescens (L.) Britt. (perilla) essential oils were investigated for their deterrent and larvicidal activity. Green perilla oil showed more promising deterrent and larvicidal activity than red perilla oil. Therefore, we focused on the principle compound in green perilla oil and, in addition, perilla alcohol and perillic acid were included for the activity relationship on the allylic methyl groups on carbon 7. Chemical composition of green and red perilla essential oils was compared using gas-chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). In biting deterrent bioassays, biting deterrence index (BDI) values for compounds methyl perillate (0.73), perillic acid (0.71), perilla alcohol (0.69), perilla aldehyde (0.62), caryophyllene oxide (0.60), and limonene (0.52) indicated good biting deterrent activity but the activity was significantly lower (proportion not biting (PNB) value 0.84) than the positive control N,N-diethyl-3-methylbenzamide (DEET) at 25 nmol/cm(2). In larval bioassays, methyl perillate was the most toxic compound with LC50 of 16.0 ppm. Methyl perillate was the most active compound against A. aegypti larvae and this compound may offer a new biodegradable mosquito control agent, USDA-ARS [56-6402-1-612]; Deployed War-Fighter Protection Research Program Grant - U.S. Department of Defense through the Armed Forces Pest Management Board; Mississippi Agricultural and Forestry Experiment Station, This study was supported in part by USDA-ARS grant No. 56-6402-1-612, Deployed War-Fighter Protection Research Program Grant funded by the U.S. Department of Defense through the Armed Forces Pest Management Board and by a Special Research Initiative grant from the Mississippi Agricultural and Forestry Experiment Station.

Insecticides of the natural origin are an important alternative to the synthetic insecticides that are being employed for the preserving stored products. The volatiles obtained from T. cinerariifolium (=Pyrethrum cinerariifolium) is being used for many types of insecticidal applications; however there is a very little information on the insecticidal activity of the essential oils of other Tanacetum species. The main purpose of the present study is to determine the chemical composition of T. macrophyllum (Waldst. & Kit.) Schultz Bip. essential oils and evaluate their insecticidal activity against S. granarius as well as its other beneficial biological activities. Highest contact toxicity was observed in the leaf oil of (88.93%) against S. granarius. The flower oil showed considerable fumigant toxicity against L. minor at 10 mg/mL application concentration (61.86 %) when compared with other samples at the same concentration. The highest DPPH (2,2-Diphenyl-1-picrylhydrazyl) scavenging activity (47.7%) and phosphomolybdenum reducing activity was observed also for the flower oil of T. macrophyllum at 10 mg/mL concentration. The essential oils were analyzed by GC, GC/MS. The flower and leaf oils were characterized with γ-eudesmol 21.5%, (E)-sesquilavandulol 20.3%, copaborneol 8.5% and copaborneol 14.1%, 1,8-cineole 11%, bornyl acetate 9.6%, borneol 6.3% respectively. AHC analysis of the qualitative and quantitative data obtained from the essential oil composition of the T. macrophyllum essential oil from the present research and previous reports pointed out that two different chemotypes could be proposed with current findings which are p-methyl benzyl alcohol/ cadinene and eudesmane chemotypes.

WOS: 000451238000018, PubMed ID: 29908309, Thymus sipyleus Boiss. subsp. sipyleus var. sipyleus of the Lamiaceae, locally known as thyme scented lemon, which is an endemic taxon collected from Sivas in Anatolia, was investigated in this study due to its folk medicine use against rhinosinusitis. The aromatic characteristics of the plant material gave the idea for the detailed evaluation of the volatiles and essential oil thereof. Consequently, the oil was obtained by Clevenger type hydrodistillation followed by gas chromatography-flame ionization detector (GC-FID) and gas chromato-graphy/mass spectrometry (GC/MS) analyses for phytochemical characterization. To confirm the folk medicinal use against sinusitis, in vitro antimicrobial activities of the essential oil was evaluated by agar diffusion, microdilution and vapour diffusion methods against selected rhinosinusitis associated strains such as Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), S. epidermidis, Streptococcus pyogenes, S. pneumoniae, Pseudomonas aeruginosa, Haemophilus influenzae and Moraxella catarrhal's. Additionally, the in vitro anti-inflammatory activity was evaluated by 5-lipoxygenase (5-LOX) inhibitory effect of the essential oil spectrophotometrically. Furthermore, the composition of the volatiles of the vapour phase of the oil was determined by headspace-solid phase microextraction (HS-SPME-GC/MS) after 15 min and 24 h in accordance with antimicrobial vapour diffusion method conditions, respectively. According to the analytical results, the main component was determined as thymol (66.2%). Whereas in the HS-SPME method p-cymene (26.1%) and gamma-terpinene (26%) were identified as the main volatile components within the 15. min., and thymol (75.3%) after 24 h, respectively. The antibacterial activity against rhinosinusitis pathogens varied between 160 and 1250 mu g/mL minimum inhibitory concentrations, with the best inhibitory effects observed against the S. aureus, S. pyogenes and M. catarrhalis. The anti-inflammatory activity of the oil was determined as 12.1 +/- 1.8% in 100 mu g/mL. The results showed the in vitro antimicrobial and anti-inflammatory potential of the oil also in vapour phase against sinusitis supporting the traditional use., Anadolu University Scientific Research Projects [BAP 1309S319], This work was supported by the Anadolu University Scientific Research Projects (BAP 1309S319), which is a part of the MSc work of N.

Volatile composition of the n-hexane and methanol extracts from E. anacampseros var. tmolea was analyzed by head space-solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). Chemical characterization of the methanolic extract was determined by LC-ESI-MS/MS. Both extracts were bioassayed against 1st instar larvae and adult female Ae. aegypti. The main components identified from the E. anacampseros var. tmolea n-hexane fraction were 1,8-cineole (27.5 %), p-cymene (25 %), ?-terpinene (12.8 %), limonene (9.9 %). Methyl hexanoate (18.8 %), methyl nonanoate (13.3 %), dimethyl succinate (6.5 %), methyl octanoate (6 %) and methyl phenylacetate (5.3 %) were identified from the methanolic fraction. The n-hexane extract showed 100 % mortality at 0.1 µg/ µL against 1st instar larvae of Ae. aegypti and the methanolic extract exhibited 83.3 % mortality at 5 µg/mosquito against adult female Ae. aegypti. The bioassay-guided study demonstrates that n-hexane and methanol extracts of E. anacampseros var. tmolea contain compounds with natural mosquito larvicidal and adulticidal activity., U.S. Department of Defense, This study was partly funded by the Deployed War-Fighter Protection Research Program via grants from the U.S. Department of Defense through the Armed Forces Pest Management Board.

WOS: 000400988100007, The essential oils obtained from the aerial parts and the roots of Conyza canadensis (L.) Cronquist (Asteraceae) at the flowering stage, collected from Turkey were simultaneously analysed by GC-FID and GC-MS. Forty-six components comprising 82.8% of the essential oil from the aerial parts and seven components comprising 96.7% of the roots oil were identified. Major constituents of the essential oil of the aerial parts were found to be limonene (28.1%), spathulenol (16.3%) and beta-pinene (9.7%), whereas cis-lachnophyllum ester (86.5%), (2Z,8Z)-matricaria ester (3.9%) and beta-pinene (2.3%) were identified to be main constituents in the volatiles of the root parts. In addition, antimicrobial activity of the essential oils was screened against Gram-positive and Gram-negative bacteria as well as one strain of fungus by broth microdilution method. Both of the essential oils exhibited antifungal activity against Candida albicans ATCC 10231 with 0.078 mu g/ml MIC values. The highest antibacterial activity was observed by aerial parts oil against Escherichia coli RSKK 234 (MIC: 0.039 mu g/ml). This is the first report on the chemical composition and antimicrobial activity of the essential oils obtained from C. canadensis growing in Turkey.

WOS: 000412968500029, Sideritis caesarea H. Duman, Aytac & Baser of the Lamiaceae is an Anatolian endemic species, and is mainly used as herbal tea and folk medicine. This present study aimed to determine and compare the chemical compositions of the volatile components of S. caesarea specimens collected from different localities in Kayseri province, Turkey: Sariz town (samples A and B), Pmarbasi-Kaynar (sample C) and Pinarbasi-Sirvan Mountain (sample D), respectively. Initially, the essential oils of the aerial parts were obtained by hydrodistillation and analysed both by gas chromatography-flame ionization detector (GC-FID), gas chromatography/mass spectrometer (GC/MS), simultaneously. Major volatile components of samples A and D were characterized as hexadecanoic acid (19.7 and 20.5%), caryophyllene oxide (6.7 and 20.2%), beta-caryophyllene (6.5 and 12.6%), respectively. In sample B, hexadecanoic acid (14.6%),) beta-caryophyllene (11.5%) and caryophyllene oxide (8.3%) were detected as the major components. Whereas caryophyllene oxide (13.7%), hexadecanoic acid (8.5%) and spathulenol (6.1%) were the main components of the essential oil of sample C. Besides the chemical profiling, in vitro antimicrobial effects of samples were evaluated against a panel of six pathogenic microorganisms. Inhibition zones of the tested samples varied against bacteria with low to moderate activity, where no susceptibility against Candida albicans was observed., Scientific and Technological Research Council of Turkey - TUBITAK [SBAG-112S581], This work was supported by The Scientific and Technological Research Council of Turkey - TUBITAK Grant No SBAG-112S581.

WOS: 000424384100004, In the present study, aerial parts of Nepeta cilicica were hydro-distilled for the essential oil. Furthermore, air-dried plant materials were extracted with methanol. According to GC-MS results, 35 compounds were characterized in the oil (totally 92%). Caryophyllene oxide, beta-caryophyllene and spathulenol (28.2, 8.9 and 4.2%) were found as main components of the oil. Sixteen compounds were detected by LC/MS, most of which were caffeoylquinic acid, luteolin and apigenin derivatives, in methanolic extract of the N. cilicica. Apart from DPPH radical scavenging activity, inhibitory effects on bacterial and yeast growth of essential oil and the methanolic extract were evaluated. Twenty-four different pathogenic bacterial and Candida strains were tested by M7-A7 and CLSI M27-A2 protocols respectively. The crude extract showed better inhibitory effects against bacteria strains than the essential oil. Both oil and the extract demonstrated strong inhibition on C. tropicalis at a concentration of 47.0 mu g/mL (MIC).

Jiaogulan [Gynostemma pentaphyllum (Thunb.) Makino] is a Chinese medicinal plant from southern Asia that has rapidly gained popularity and interest for its health-promotive and therapeutic properties. The volatile composition of jiaogulan tea was analyzed by using headspace-solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). A total of 29 volatile components were detected in the jiaogulan tea, with major compounds being benzaldehyde (15.3 %), 1,8-cineole (8.7 %), 6-methyl-5-hepten-2-one (7.8 %), (Z)-3-hexenal (7.6 %) and ?-ionone (6.3 %). The chemical characterization of methanolic extract and 5 % infusion from the G. pentaphyllum leaves was determined by using LC-ESI-MS/MS systems. Chlorogenic acids, flavonoids and gypenosides were determined. The compounds quercetin 3-O-hexoside, isorhamnetin rutinoside and kaempferol dimethyl ether were identified in the extracts for the first time. Phenolic content was determined by gallic acid equivalents and antioxidant activity of the extracts was evaluated by DPPH, ß-carotene/linoleic acid and ABTS radical scavenging assays. Both extracts showed weak antioxidant activity, Mississippi Agricultural and Forestry Experiment Station, Mississippi State University National Institute of Food and Agriculture: MIS-219060, This study was supported in part by a Special Research Initiative grant from the Mississippi Agricultural and Forestry Experiment Station and by the USDA National Institute of Food and Agriculture Hatch project MIS-219060.
