Full textThis thesis focuses on the electrochemical behavior of galvanized steel in a kombucha fermentation medium, with and without the addition of date palm leaf extracts of the Deglet Nour (PDN) and Alig (PA) varieties. The main objective was to develop an environmentally friendly and sustainable approach for corrosion protection by utilizing the synergistic properties of plant extracts and the metabolites produced during fermentation. The results show that galvanized steel immersed in kombucha accelerates fermentation through rapid sugar consumption and increased production of acetic acid and ethanol, while enhancing the bioactivity of the fermented extracts. The Deglet Nour (PDN) and Alig (PA) palm leaf extracts demonstrated partial corrosion inhibition, reducing the corrosion rate by 50% for PDN and 40% for PA compared to abiotic tests. PDN induced more localized corrosion, while PA generated more homogeneous corrosion. However, the lack of a conclusive inhibitory effect during fermentation led to the exploration of an alternative maceration method. A design of experiments helped optimize maceration extraction parameters (particle size, material-to-solvent ratio, and time). The resulting extracts showed improved antioxidant properties and a more promising inhibitory potential under simulated corrosion conditions. Tests at different concentrations (0.2 to 0.8 g/L) revealed a correlation between antioxidant activity and anticorrosion efficiency, although this relationship was not systematic. This work not only enhances understanding of the interactions between galvanized steel and the kombucha fermentation medium but also demonstrates the potential of palm leaf extracts as natural corrosion inhibitors. These findings pave the way for biomaterial applications in corrosion protection, though further studies are needed to optimize their effectiveness

Full textRelatively under-exploited, the innovation potential related to the biological activities of secondary plant metabolites is nevertheless considerable. Therefore, we chose to study the flora of the Auvergne, known for its richness and diversity, and which has many plants that are still little studied. Thanks to the regional skills in this field of activity (academic and industrial), a collaborative project has been set up to study and promote Auvergne plants with anti-inflammatory activities (PlantInAuv project 2017-2020). This thesis work was part of this project, with the aim of studying the anti-inflammatory potential of local plant extracts in vitro. In the year preceding this thesis work, a selection was made on a large sample of about 200 plants, which resulted in a first round of 15 plants selected for the project at the beginning of the thesis.In a first phase, a screening was carried out on a selection of 15 plants. The extracts of these plants were tested on a wide range of markers of inflammation using human leucocytes. These tests enabled us to identify plants with anti-inflammatory potential, some of them acting on the activation of NFκB, and to select seven of them for further experiments.In a second phase, the selected plants were evaluated by setting up a three-dimensional joint inflammation model. The extract of Luzula sylvatica proved to be particularly interesting: it could provide interesting antioxidant protection against cartilage damage and reduce inflammation of the joint, by reducing the secretion of PGE2 in the synovial fluid. In addition, it could act directly on chondrocytes by decreasing the expression of proteases and thus preventing the degradation of the extracellular matrix.In a third phase, the selection of seven plants was evaluated in a skin inflammation model, using an original model mimicking an inflamed skin i.e. fibroblasts in the presence of macrophages with a pro-inflammatory profile. Once again, we chose to present the results obtained with the Luzula sylvatica extract. It showed good antioxidant properties and modified the pro-inflammatory polarization of macrophages. In addition, it dampened the expression of several genes linked to TGFβ in the fibroblasts, indicating that it could be of interest in preventing the formation of fibrotic scars. Of the 15 plants initially selected in the project, two (Bupleurum rotundifolium and Luzula sylvatica) have been, or will be, the subject of an academic valorization with publication of the results. The rest of the plants selected following the screening phase will be valorised by the industrial partners of the project

Full textThis report is dedicated to the chemical study of rhizomes, essential oil, and extracts of Iris germinaca L. And Iris pallida Lam. From Morocco. A method of direct quantification of irones in rhizomes by HS-SPME / GC is presented first and compared with a classical method (solid / liquid extraction followed by quantification by GC) before studying the evolution of the irones content according to the storage time of rhizomes. The study of the chemical composition of Iris germanica resinoid is then presented. It reveals the presence in the resinoid of flavonoids, iridals, iridals esters, irones, fatty acids, steroids, alkanes and carbohydrates. The comparison of Iris germanica and Iris pallida resinoids is also presented as well as that of iris pallida resinoid obtained from rhizomes resulting from various geographic origins. This study led to the identification of four characteristics compounds of the pallida species : the 2,6,4-‘’trihydroxy-4-methoxybenzophenone, the 8-hydroxyirigenine, the 2,3-dihydroirigenine and the iriflophenone. These four compouds also allow distinguishing Iris pallida resinoids obtained from rhizomes of four geographic studied origins (Morocco, Italy,France and China). The chemical composition of others Iris germanica extracts (absolute, alcohol extract and supercritical CO2 extract) is also presented. Finally, the distillation and the quality of the butters of iris from Morocco is presented (Iris germanica and Iris pallida) and a possibility of valuation of the distillation by-products is proposed. In this way, we contribute to a better knowledge of rhizomes, essential oil and extracts of vaious iris cultivated in Morocco

Full textIn order to obtain new dermo-cosmetic and therapeutic agents from traditional medicinal plants, highlighting new sources of active substances at the skin level, treatment of the acne, oxidative stress and cell regeneration, five Venezuelan leguminous have been selected. Three types of extracts: aqueous, ethanolic and protein derived from the aqueous extract have been studied. The cytoprotective effect, the ability of the stimulation of cell growth and antioxidant efficiency were analyzed in dermal fibroblasts 3T3 cells. Our results showed that Machaerium floribundum extracts had a very high antioxidant activity at low concentrations. This antioxidant activity is linked to the presence of condensed tannins (polymers of anthocyanins). Also a good antibacterial activity was found using Machaerium ethanolic extracts against bacteria involved in the acne process: Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus offering an alternative for acne treatment
