| genetic variation for sensitivity to a thyme monoterpene in associated plant species. | recent studies have shown that plant allelochemicals can have profound effects on the performance of associated species, such that plants with a history of co-existence with "chemical neighbour" plants perform better in their presence compared to naïve plants. this has cast new light on the complexity of plant-plant interactions and plant communities and has led to debates on whether plant communities are more co-evolved than traditionally thought. in order to determine whether plants may indeed ... | 2010 | 19921272 |
| antifungal activity of the essential oil of thymus pulegioides on candida, aspergillus and dermatophyte species. | the composition of the essential oil of thymus pulegioides and its antifungal activity on candida, aspergillus and dermatophyte fungal strains were studied. essential oil from the aerial parts of the plant was obtained by hydrodistillation and analysed by gc and gc-ms. the oil showed high contents of carvacrol and thymol. the mic and minimal lethal concentration were used to evaluate the antifungal activity against candida (seven clinical isolates and four atcc type strains), aspergillus [five c ... | 2006 | 17005785 |
| hypochlorous acid scavenging properties of local mediterranean plant foods. | oxidative modification of low density lipoprotein (ldl) is involved in the pathogenesis of atherosclerosis and coronary heart disease, which are low in the mediterranean area possibly due to a high dietary proportion of plant foods. ethanolic extracts were prepared from more than 120 mediterranean edible plants collected in remote areas (which maintain their traditional diet) and their antioxidant potential was studied. extracts derived from agaricus campestris, cynara cardunculus, thymus pulegi ... | 2004 | 15736921 |
| solid-phase microextraction of volatile components from natural grassland plants. | the volatile components from nine plants growing on natural grasslands in auvergne, central france, selected for the broad qualitative and quantitative diversity of their terpenoid fractions, were analyzed by high-resolution gas-phase chromatography and mass spectrometry (hrgc-ms) after static headspace solid-phase microextraction (shs-spme). shs-spme allowed all the plant material to be analyzed under the same conditions despite its wide-ranging composition. this is not always possible with oth ... | 2001 | 11170578 |
| traditional knowledge on medicinal and food plants used in val san giacomo (sondrio, italy)--an alpine ethnobotanical study. | this work increases the ethnobotanical data from northern italy and, in particular, the lombardy region, till now poorly documented, safeguarding the local folk knowledge, and provides information on new or scarcely reported properties of medicinal plants, whose traditional use needs to be validated experimentally. | 2013 | 23220197 |
| the alpha-terpenyl acetate chemotype of essential oil of thymus pulegioides l. | the composition of the essential oils of thymus pulegioides l. plants growing wild in vilnius district (lithuania) with "ester", lemon and carvacrol (phenol) odours were collected in one location and investigated by gc, gc/ms and ir-spectroscopy. the essential oils with lemon and carvacrol odour belong to corresponding known citral-geraniol and carvacrol chemotypes. the essential oil of plants with "ester" odour containing 50-70% of alpha-terpenyl acetate belong to alpha-terpenyl acetate chemoty ... | 2001 | 11068125 |
| vibrational spectroscopy and electrophoresis as a "golden means" in monitoring of polysaccharides in medical plant and gels. | in recent years, some bioactive polysaccharides isolated from natural sources have attracted much attention in the field of biochemistry and pharmacology. of them, polysaccharides or their glycoconjugates were shown to exhibit multiple biological activities including anticarcinogenic, anticoagulant, immunostimulating, antioxidant, etc. pharmacotherapy using plant-derived substances can be currently regarded as a very promising future alternative to conventional therapy. the advanced biotechnolog ... | 2012 | 22465769 |
| a relic of medieval folklore: corpus christi octave herbal wreaths in poland and their relationship with the local pharmacopoeia. | herbal wreaths are blessed all over poland on the eighth day of the corpus christi octave (usually in june). they used to contain many species of aromatic and medicinal plants, both collected from the wild and cultivated. the aim of this study was to document the present composition of wreaths using photographs (etic perspective) and questionnaires (emic perspective) and compare it with the local pharmacopoeia, the composition of assumption day bouquets (blessed in august) and historical data on ... | 2012 | 22575705 |
| effects of meteorological conditions and plant growth stage on the accumulation of carvacrol and its precursors in thymus pulegioides. | the effects of meteorological conditions (temperature, rainfall, photosynthetically active solar radiation (par) and sunshine duration) and plant growth stages on the quantitative composition of a secondary metabolite - essential oil and its main compounds, in the carvacrol chemotype of thymus pulegioides l. (lamiaceae) cultivated in open ground were studied under the same micro-edaphoclimatic environmental conditions for six years. the essential oil was isolated by hydrodistillation, the analys ... | 2016 | 27174744 |
| the main citral-geraniol and carvacrol chemotypes of the essential oil of thymus pulegioides l. growing wild in vilnius district (lithuania). | thymus pulegioides l. with lemon and carvacrol odor form the major part of plants growing wild in all 10 investigated localities during 1995-1997. the main components of the citral-geraniol chemotype of lemon-scented essential oil are the following (%): geraniol (14.9-30. 8), geranial (trans-citral, 9.7-19.7), beta-caryophylene (6.0-11.4), nerol (4.1-11.8), and neral (cis-citral, 0.1-9.5). the essential oil of carvacrol chemotypes contain more compounds that are characteristic of the thyme genus ... | 1999 | 10552723 |
| transcription factors as targets of the anti-inflammatory treatment. a cell culture study with extracts from some mediterranean diet plants. | during the inflammatory response at least 2 transcription factors, nf-kappab and ap-1, are involved in the altered profile of gene expression. we used human hepatoma (hepg2) and human umbilical vein endothelial cells (huvec) as a model system: nf-kappab and ap-1 were activated by the proinflammatory cytokine il-1 in the absence or presence of 21 selected plant extracts and the effect was evaluated by the electrophoretic mobility shift assay (emsa). in both types of cells activation of nf-kappab ... | 2005 | 15800392 |
