The population and morphological variance of the quantitative content of the acids in yarrow plants growing in the natural habitats of Lithuania was also determined for the first time. The overall amount of phenolcarboxylic acids was determined to be 58,690±4.279 mg/g in 70 percent ethanol extracts of the herb. It was also determined that significant variability exists in indicators of the phenolcarboxylic acid content of A. millefolium plants. This is directly dependent on the morphological part of the plant. The total average of the phenolcarboxylic acids content in flowers was 58,029±3,492 mg/g. The total average in leaves was 102,150±7,50 mg/g, almost two times higher the content found in the flowers and herbs. The average acids content accumulated in stems was 22,722 ± 2,928 mg/g. Determinated sign variability of the content of phenolcarboxylic acids in the investigated cenopopulations of yarrow. The total acids content of different cenopopulations in the raw plant materials of yarrow ranged from 33,490 to 86,474 mg/g, in flowers - from 40,240 to 73,022 mg /g, in leaves - from 74,110 to 150,176 mg/g, in stems - from 15,605 to 43,381 mg/g.

Several changes in land use during the last 50 years of 20th century had a significant impact on the composition of traditional meadows. The abundance of many plant species typical for traditionally managed meadows has declined. But some of these species have found a refuge in habitats such as field margins and road verges. The aim of this study was to describe how the reproduction success of two related Achillea species A. millefolium agg. and A. ptarmica depends on (i) the particular habitat in which they grow (meadow/verge); (ii) the abundance of pollinators in the study site; and (iii) timing of flowering within the season. Moreover, the longevity of individual flowers of the two taxa has been studied in order assess the width of the time frame the reproduction takes place in. These objectives were achieved by means of measuring plant total seed production and germination as proxies of reproductive success both in meadow and verge populations at the beginning, peak and end of the flowering season of the two species in 2012. The plants were chosen at plots, where concurrently a pollinator survey has been conducted as the part of the broader project. The durations of the male and female phases of individual flowers have been studied in separate experiments.

Sua abrangência é vasta e engloba fins variados, inclusive em relação à saúde bucal. O controle do biofilme bacteriano dentro das diversas especialidades odontológicas é de grande importância, pois aponta para a prevenção de várias afecções bucais. Quando a remoção mecânica do biofilme é deficiente, podem ocorrer lesões de tecido duro (cáries) e/ou mole (doenças periodontais). A eficácia de plantas medicinais, tanto em dentifrícios como em enxagüatórios bucais, tem sido investigada. Os resultados têm sugerido que os componentes de origem vegetal podem ser empregados como apoio à terapia das doenças periodontais e como profilaxia de rotina. Este trabalho teve como objetivos avaliar a ação biológica de formulações para higiene bucal, contendo, em associação, extratos hidroalcoólicos das espécies vegetais Nasturtium officinale (agrião), Rosmarinus officinalis (alecrim), Tabebuia impetiginosa (ipê roxo), Achillea millefolium (mil-folhas) e Plantago major (tanchagem). Trabalhos anteriores sugerem possível efeito antiinflamatório e alteração da qualidade do biofilme dento-bacteriano, devido as substâncias ativas desses vegetais. Após os estudos de pré-formulação e obtenção do gel dentifrício e do enxagüatório bucal, foram realizadas avaliações da atividade antibacteriana (frente à Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Enterococcus faecalis e Pseudomonas aeruginosa), atividade antiinflamatória e imunológica, para os extratos vegetais e para as formulações. E foram ainda realizados estudos clínicos iniciais, considerando-se os parâmetros odontológicos para a avaliação do Índice de placa, Índice Gengival, Recessão Gengival e... . / The use of natural resources in popular medicine is a millenary practice and it persists until nowadays. This habit is embracing and wide and it conglomerates multiple purposes, included those related to oral health. It’s very important to control bacterial film in many odontologic specialties, because this control helps to prevent several oral diseases. When the mechanical removal of the bacterial film is inefficient, there can occur hard tissue lesions (carious lesions) and/or soft tissue lesions (periodontal diseases) The effectiveness of medicinal herbs in dentifrices, as well as in mouthwashs have been investigated. The results have suggested that the herbs components can be utilized as a support in the periodontal diseases therapies and in the routine prophylaxis. It was the purpose of the present study to evaluate the biological action of various formulations to bucal hygiene, containing, in association, hidroalcoholic extracts from the following species: Nasturtium officinale, Rosmarinus officinalis, Tabebuia impetiginosa, Achillea millefolium and Plantago major. Previous works suggested that there are possible anti-inflammatory effects and an alteration of the bacterial dental film quality, due to the active substances of these herbs. After studying a previous formulation and obtaining the dentifrice and the mouthrinse, it was evaluated the bacterial activity (related to Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Enterococcus faecalis and Pseudomonas aeruginosa), the antiinflammatory and the immunological activities, for the herbs extracts and for the formulations...

In present thesis, I treat the topic of impacts of plant-animal interactions, namely herbivory and pollination, on plant life cycle and lifetime fitness. First, I identify the components of the impact of plant-animal interactions: i) interaction frequency; ii) per-interaction effect; iii) sensitivity of the plant's life cycle to the changes in vital rate impacted by the animals. Furthermore, I also classify other causes changing the outcome of a plant-animal interaction into two categories: i) plant's traits; ii) plant's environment. A review of extant literature on the topic revealed that especially the role of plant's environment in changing the outcome of plant-animal interactions is largely understudied and I attempt to reduce this gap in knowledge in the five detailed studies encompassed in this thesis. The detailed studies focus on a model system of Central European wet grasslands and especially on three species typical to it: Succisa pratensis, Achillea millefolium and A. ptarmica. The first two studies examine the effects of environment on frequency of plant- animal interactions. The next two studies are more integrative, one focusing on the impacts of different herbivore groups on the complete life cycle and the other on interaction of herbivory and pollination on plant lifetime fitness....

Les plantes aromatiques font parties des richesses naturelles du patrimoine de la région Midi-Pyrénées mais apparaissent cependant de moins en moins valorisées. Dans le cadre de la recherche de nouveaux aromatisants naturels de type WONF, nous avons choisi d'adopter la voie de valorisation des plantes aromatiques médiévales de cette région car elles ont toujours fait l'objet de cueillette à l'état sauvage sans jamais être cultivées. Dans une première étape, une étude bibliographique a été réalisée, à partir d'anciens ouvrages botaniques et de bases de données scientifiques, afin d'identifier les plantes régionales traditionnellement utilisées par nos ancêtres pour leurs activités aromatisantes, culinaires ou médicinales. Nous avons sélectionné cinq plantes aromatiques : Achillea millefolium, Calamintha grandiflora, Tanacetum balsamita, Myrrhis odorata et Monarda didyma. Dans une deuxième étape, des études physico-chimiques, sensorielles et biologiques des fractions volatiles et non volatiles, obtenues après extractions des plantes médiévales sélectionnées, ont été réalisées pour juger de leurs activités aromatiques, antioxydantes et antibactériennes ainsi que de leur intérêt dans le cadre de nouvelles réglementations européennes. Les résultats de ces travaux montrent des activités odorantes, antioxydantes et antibactériennes significatives pour l'ensemble des plantes sélectionnées. Dans une troisième étape, du fait de la rareté du végétal étudié, nous nous sommes intéressés à deux voies analytiques d'évaluation rapide de la composition de l'huile essentielle native de ces plantes aromatiques ; premièrement au moyen d'un échantillonnage classique couplé à un détecteur à forte sensibilité comme la chromatographie bidimensionnelle et deuxièmement par un échantillonnage spécifique couplé à un détecteur classique pour lequel nous avons développé un appareillage novateur dénommé "Crushing Finger Device" (CFD). Ce dernier permet de mimer instrumentalement l'écrasement de la feuille entre les doigts et de piéger les composés volatils odorants émis en vue de leur analyse chromatographique ultérieure. Enfin, pour une application pré-industrielle, afin d'élargir le champ d'application de ces plantes aromatiques, des études d'infusion des plantes et d'aromatisation des huiles végétales par les huiles essentielles ont été mises en place. Durant le processus d'aromatisation de l'huile végétale, les volatils émis par la plante ou par l'huile essentielle donnent un goût et une saveur spécifique tout en délivrant une activité biologique notable. / Midi-Pyrenees region has a rich and unvalorized wild vegetal heritage, especially for aromatic plants. In the framework of the search for new natural flavorings e.g. WONF, we chose to adopt the way of valorization of the medieval aromatic plants of this region, because they have been always picked in a wild state without being ever grown. In a first step, a global bibliographical survey study based on historical books, library archived documents and computerized data banks, was made in order to identify regional plants which were used by our ancestors for their odorous, culinary or medicinal activities. We selected five aromatic plants, e.g. Achillea millefolium, Calamintha grandiflora, Tanacetum balsamita, Myrrhis odorata and Monarda didyma. In a second step, physico-chemical, sensory and biological studies of volatiles and non volatiles fractions, obtained by extractions of the selected medieval plants were carried out, to judge their aromatic, antioxidant and antibacterial activities and their interest within the framework of new european regulations. Theses results show a significant odorous, antioxidant and antimicrobial activities for all selected plants. In a third step, such plants were rare or their harvesting problematic, inducing a limited sampling. We decided to investigate two strategic approaches to perform a rapid evaluation of native essential oil, based either on a classic sampling with a specific/ultra sensitive detection such as Comprehensive GC, nor the use of a specific/high effective sampling system with a classic detection. This last methodology was based on a self designed apparatus “Crushing Finger Device” (CFD), allowing to copy the crushing of leaves between fingers and to trap the volatiles emitted to their later chromatographic analysis. Finally, in the aim to expand the use of aromatic plants, also to enlarge the assortment of oil products, a pre-industrial application were carried out. Infusion of plants and flavoring of vegetable oil by essential oil were studied. During processing of aromatized vegetable oil, volatiles from added aromatic plants or essential oil migrate to oil to give a specific aroma and a significant biological activity. Plantes aromatiques oubliées, Huile essentielle, Antioxydant, Antibactérien, Simulateur de froissement, Composés d’arômes, Achillea millefolium, Calamintha grandiflora, Tanacetum balsamita, Myrrhis odorata, Monarda didyma.

Competition between plant individuals and how plants alter soil properties are key processes which drive changes in plant communities over time. Estimating the relative importance of these processes and how they affect plant growth in different ecological contexts and communities is an active area of research. Furthermore, interdependencies between the two processes have been suggested to occur in many cases, but research in this area is also lacking. In this study, soil conditioned by common yarrow (Achillea millefolium) was collected from field plots and was then used in a growth chamber competition experiment, which controlled for plant-soil feedbacks. Measured soil properties such as soil pH, soil nitrogen, and soil texture were primarily used as background data in the experiment. Field parameters such as light availability, plant density, and grass to forbs ratio were used to predict optimal A. millefolium habitat in relation to other vascular plant species. The results indicate that A. millefolium was a weaker competitor than cornflower (Centaurea cyanus), while a positive plant-soil feedback effect was observed by A. millefolium grown in field soil. Intraspecific competition had a strong negative effect on A. millefolium growth when grown in non-conditioned soil, but not when grown in A. millefolium conditioned soil. Finally, competition and plant-soil feedbacks appeared to be additively affecting A. millefolium growth, meaning the plant-soil feedback effect did not have a disproportionate effect on competitive outcomes, or vice versa. The findings of this study can be of interest to conservationists or farmers who wish to predict how plant communities respond to plant competition and plant-soil feedbacks as processes.
