Texto completoThis thesis was realized in the laboratory of Pharmacognosy, in the Pharmacy section of the Bourgogne University. The main theme of this laboratory is the research of natural saponins from the tropical biodiversity, with antitumoral activities. These molecules are triterpenic or steroidic glycosides, well known for their various pharmacological activities. The study of 6 species belonging to 3 different families : Acanthophyllum elatius, A. lilacinum, A. sordidum and Arenaria montana (Caryophyllaceae), Securidaca welwitschii (Polygalaceae) and Allium schoenoprasum (Alliaceae), led to the isolation and characterization of 24 natural glycosides. Among them, 13 were triterpenic saponins with 10 new structures and 11 were steroidic saponins with 7 new structures. The spectral analysis was achieved using mainly 2D NMR and mass spectrometry. The cytotoxic activities of 10 isolated compounds were evaluated on 2 strains of human colon cancer cells (HT-29 et HCT 116) and 9 were active ones. Structure/activity relationships were also proposed

Texto completoThis work presents the phytochemical study of five Peruvian plants, Myrsine latifolia, M. congesta and M. sessiliflora (Primulaceae ex Myrsinaceae), Poraqueiba sericea (Icacinaceae) and Dendrobangia boliviana (Cardiopteridaceae ex Icacinaceae). The study of the three Myrsine enabled us to isolate eleven compounds already known in the literature which were tested for their antileishmanial (screening of Leishmania promastigotes luminescence) and cytotoxic activities (in vitro test on fibroblasts). The results were negative for both activities. From the stems of Poraqueiba sericea we were able to isolate eleven compounds including six triterpenes, three monodesmosides saponins described for the first time in this plant family and two secoiridoides. Various biological activities have been evaluated for these molecules: leishmanicidal, cytotoxic and anti-elastase activities. Only the last testing has suggested activities for two tripterpénoïdes and the secologanoside. From Dendrobangia boliviana fourteen saponins have been isolated including twelve novel glycosides of the serjanique or phytolaccinique acids. The analysis by LC-NMR allowed us to identify five other saponins with new structures. These compounds were tested for their biological activities and showed no hemolytic activity and three of them showed a cytotoxicity on fibroblasts. The antileishmanial test showed no activity. In bioautography (HPTLC) these saponins showed an interesting potential for different biological activities (tyrosinase, α and β-glucosidase and acetylcholinesterase)

Texto completoThis thesis was carried out at the Laboratory of Pharmacognosy and the Laboratory of Pharmaceutical technology, at the UFR Sciences de Santé, circonscription Pharmacy, in the University of Burgundy Franche-Comté, to find new natural molecules to encapsulate. First of all, we focused on the natural saponins from plants of the Vietnam biodiversity and the french horticulture, belonging to the three genera Dracaena, Cordyline (Asparagaceae) and Weigela (Caprifoliaceae). The work led to the successful isolation and elucidation of 42 natural saponins using various chromatographic techniques. The structures were determined by ESI mass spectrometry and NMR spectroscopy. Among the 17 pure compounds obtained from three species of the Weigela genus, 9 oleanolic acid and hederagenin glycosides are previously undescribed ones. From the two species Dracaena braunii and Cordyline fruticosa “Fairchild red”, we isolated and characterized 18 steroidal saponins including 7 new spirostane-types and 6 new furostane-types ones. The cytotoxic activities of the majority of isolated saponins were evaluated against mouse colon cancer (CT26 cells), mouse melanoma (B16 cells) and human liver cancer (HepG2 cells) by MTS assays. The structure / activity relationships were also proposed.On the other hand, we selected a well-known natural molecule to develop encaspulation tests. Among the natural products, curcumin has very interesting therapeutic properties but exhibits both a poor solubility and a low bioavailability, limiting the administration by the oral route. The purpose of this study was to improve the solubility and bioavailability of curcumin as well as simultaneously achieve controlled release in gastrointestinal tract. Pectinate gel beads were prepared based on ionotropic gelation method with the presence of vaious surfactants. After drying, these beads were investigated for physicochemical characteristics (morphological aspects, encapsulation efficiency, stability, physical state) and dissolution kinetics (in vitro release). Antioxidant activity was also determined with DPPH assay. Kolliphor HS15® seems to be the best promising surfactant to increase stability and bioavailability of curcumin

Texto completoThis @PhD thesis presents the synthesis of nine disaccharides consisting of a-L-rhamnopyranose/a-L-arabinopyranose, ß-D-xylopyranose/a-L-arabinopyranose and ß-D-glucopyranose/a-L-arabinopyranose. The anomeric position of these disaccharides were then activated and these compounds were coupled to a hederagenin derivative, giving access, after total deprotection to a serie of 12 saponins. A second serie of hederagenin saponins (D-cellobiose, D-lactose, D-maltose, D-melibiose, D-gentiobiose or D-isomaltose osidic moiety) was also synthesized by the trichloroacetimidate glycosylation method. All of the resulting saponins were then tested for their hemolytic activity as either the free carboxylic acid or as the coresponding methyl ester in order to establish structure-activity relationships. The cytotoxic activity of the free carboxylic acid saponins derivative from a-hederin, was also measured in vitro on KB cells. Another part of this thesis deals with the synthesis of isomaltose derivatives. Isomaltose trichloroacetimidate was synthesized in five steps from D-amygdalin by acid catalyzed rearrangement of the interglycosidic bond

Texto completoFrom decade, plants are used in traditional healer to treat many diseases. This could be explained by microorganism pharmaceutical drug resistance. Beside, the poverty limits also access to modern treatment. That is why the present work deals with extraction, isolation, structural elucidation, chemical transformation and biological evaluation of secondary metabolites isolated from the wild and cultivated species of Triumfetta cordifolia A Rich (Tiliaceae). From the organic extract of twigs and leaves of wild T. cordifolia, four new compounds were characterized (two ceramides and two triterpens) by successive chromatography methods and identified as (2R, 6Z)-2-hydroxy-N-[(2S,3S,4R)-1,2,4-trihydroxyhexacosan-2-yl]heptadec-6enamide, {(2R)-N-(1S,2R,3E,6Z,9Z,12Z,15Z)-1-[(beta-D-glucopyranosyloxy)methyl]-2-hydroxy heneicosa-3,6,9,12,15-pentaen-1-yl}-2-hydroxytetradecanamide, 3-O-propanoyl-29-O-triacontanoylstigmasta-5,22-diene-3beta,29-diol et l'acide 2alpha,3beta,19alpha-trimethoxyurs-12-ene-24,28-dioique-24-[(2alpha,3beta)-24,28-bis(beta-D-glucopyranosyloxy)-2-hydroxy-24,28-dioxours-12-en-3-yl] ester acid..These compounds were obtained together with eleven known compounds identified as heptadecanoic acid, beta-sitostérol glucopyranoside, friedelin, lupeol, betulin, oleanolic acid, maslinic acid, corosolic acid, the mixture of stigmasterol and beta sitosterol, heneicosanoic acid and trans-tiliroside. From the organic extract of twigs and leaves of cultivated species, ten products were isolated ; three among of them have not yet been identified, four of them were already obtained from the wild species and the rest were identified as Tormentic acid, beta-carotene and 24-hydroxytormentic acid. The structures of these compounds were determined on the basis of NMR data(1H, 13C, two dimensional NMR analyses), mass spectrometry structure of new compounds were confirmed by chemical transformations while those of known compounds were confirmed by comparison of their physical and spectral data with those reported in the literature and with authentic samples for some of them. Stigmasterol was subjected to different oxidation reactions. The cytotoxic activities of the products and some isolated compounds against human fribosarcoma cell line HT1080 were evaluated. The flow cytometry was used to carry out this assay and some drugs showed good cytotoxic activities although inducing at the same time the apoptopic and necrotic dead of cells. The antioxidant properties of some fractions and compounds were also evaluated by FRAP method. Trans-tiliroside and its fraction showed good antioxidant activity. This work reveals the preventive and curative character of both eatable plants since these species could be used against oxidative stress. Other biological studies could be deepened to highlight the anticancer property of some isolated compounds

Texto completoVitis vinifera is susceptible to many pathogens. These past few years, treatment policies led to the withdrawal of many pesticides. Renee, no chemical treatments are available to treat some grapevine diseases such as the grapevine trunk diseases caused by fungi complexes and the grapevine fanleaf degeneration, a viral disease transmitted from grapevine to grapevine by vector nematodes. Grapevine is known for the production of secondary metabolites as a response to pathogen infections. In this work, we focused on phytoanticipins such as triterpenoids, that are found as preformed compounds and that confer a basal resistance level to plants. First, a chemical analysis was made on the triterpenoid composition of some grapevine cultivars and organs. This study revealed that the triterpenoid composition is specific to the V. vinifera cultivar and the organ. In a genomic approach, 9 candidate genes involved in the triterpene biosynthesis were identified and their expression was studied in different organs, varieties and biotic or abiotic stress conditions. This explorative study shows correlations between gene expression and differential triterpene production at the leaf surface of the different varieties. In the last part of this study, the use of glycosylated triterpenes, also called saponins, as a substitution solution to withdrawed treattnents against major grapevine diseases was tested. Therefore, the efficiency of saponins extracted from gypsophila and quillaja was tested against fungi associated to grapevine trunk diseases and some nematodes vector of the grapevine fanleaf degeneration. These tests evidenced that the fungi were able to avoid saponins toxicity, whereas such treatment was efficient to kill nematodes. In order to evaluate the effect of the treatment on the environment, the efficient doses were tested and bad no significant impact on some bioindicators

Texto completoScientific research about alternatives to in-feed antibiotics used as growth promoters is a blooming subject since their european ban in 2006. The aim of this word was to evaluate the interest in adding extracts from saponin containing plants to the diet of dairy cows to reduce enteric methane (CH4) production and ammonia (NH3) concentration in the rumen fluid. A selection of 6 plants growing locally (e. G. Saponaria officinalis), 5 industrial by-products (e. G. Chenopodium quinoa), and two saponin containing plants from the animal feed market (Yucca schidigera and Quillaja saponaria) was evaluated in this context. Inhibition of the methanogenesis, without negative impact on volatile fatty acids, was observed with extracts from Saponaria officinalis and Camellia ofeifera (-9 to -10%). Extracts from primula veris, Chenopodium quinoa and Gypsophila paniculata showed the highest potential to decrease NH3 concentration (-26 to -31%). The chemical profile of the extracts was determined by high performance liquid chromatography coupled to mass spectrometry, in order to characterise their profile in saponins. . .

Texto completoThis thesis was carried out in the Laboratory of Pharmacognosy, in health department of the University of Burgundy. The principal theme of this Laboratory is the research of natural compounds from tropical biodiversity, mainly saponins. These molecules are known for their various pharmacological activities. The study of 3 species belonging to 2 different families: Chlorophytum blepharophyllum Schweinf. ex Baker, Ornithogalum dubium Houtt (Asparagaceae) and Weigela × « kosteriana variegata » (Caprifoliaceae), led to the isolation and characterization of 16 natural glycosides by column chromatography, medium pressure liquid chromatography, and vacuum liquid chromatography. The spectral analysis was achieved using mainly 2D NMR and mass spectrometry. Among them, 4 were phenolic glucosides, 8 were steroidic saponins with 6 new structures and 4 were triterpenic saponins with one new structure. The cytotoxic activities of 5 isolated steroidic saponins were evaluated on 2 strains cancer cells (A549 and HL 60). The results showed a low sensitivity of these two cell lines to these saponins. The toxic and teratogenic effects of 3 triterpenic saponins were also determined in by using an in vivo zebrafish assay. The results showed a lethal effect at low concentrations of these 3 saponins. Structure / activity relationships have been proposed

Texto completoThis thesis was carried out in the Laboratory of Pharmacognosy, in health department of the University of Burgundy. The principal theme of this Laboratory is the research of natural compounds from tropical biodiversity, mainly saponins with antitumoral and immunomodulatory activities. These molecules are triterpenic or steroidic glycosides, well known for their various pharmacological activities. The study of 4 species belonging to 3 different families: Dracaena marginata L., Dracaena fragrans Ker Gawl (Asparagaceae), Allium flavum L. (Amaryllidaceae) et Weigela stelzneri (Caprifoliaceae), led to the isolation and characterization of 26 natural glycosides. Among them, 22 were steroidic saponins with 6 new structures and 4 were triterpenic saponins with 3 new structures. The spectral analysis was achieved using mainly 2D NMR and mass spectrometry. The cytotoxic activities of 10 isolated compounds were evaluated on 2 strains cancer cells (SW480 and EMT-6), and 3 compounds for studying the modulatory effect of the production of pro-inflammatory cytokine, interleukin IL-1β on PBMCs stimulated with LPS. Our results show that six of them have moderate cytotoxic activity on both cancer cell lines. However, two oleanane-type triterpene saponins exert the strongest cytotoxicity on both cancer cell lines compared to internal references (Etoposide and Methotrexate). Moreover they show a significant effect of modulating the production of interleukin IL-1β on PBMCs and thereby a strong anti-inflammatory potential. Structure / activity relationships have been proposed

Three plants having an in vitro antiplasmodial activity were selected for phytochemical and pharmacological studies. From the root of Erioglossum edule, six new saponins were identified. They are glycosides of 3b-hydroxytirucalla-7,24-dien-21-oic acid and of 3b-hydroxy-21b (a)-methoxy-21 (S) and 23 (R)-epoxytirucalla-7,24-diene From the tuber of Stephania rotunda, sixteen alkaloids were isolated. The major alkaloid, cepharanthine has in vitro antiplasmodial activity (IC50: 0. 61 μM). This compound showed synergistic effect when associated with chloroquine and additive effect when associated with artesunate or other alkaloids. Cepharanthine at 10 mg/kg displayed in vivo antimalarial activity in mice infected by Plasmodium berghei. This alkaloid showed leishmanicidal activity and was cytotoxic. From Vernonia cinerea ten sesquiterpene lactones belonging to hirsutinolide group were identified. Two of them are new: - Vernolide C [8-a-(3-chloro-2-hydroxy-2-méthylpropanoyloxy) hirsutinolide- 13-O-acétate] - Vernolide D [8-a-(4-hydroxytigloyloxy)-hirsutinolide-13-O-acétate]. These compounds have in vitro antiplasmodial activity with IC50 between 3. 1 and 9. 2 μM. These results justify the traditional use of these plants as antimalarial agents in Cambodia

Texto completoPoiretia tetraphylla (Poir.) Burk., pertence a família Leguminosae, subfamília Papilionoideae. É conhecida popularmente como erva-de-touro-miúda ou chá-dos-pampas, ocorre no Brasil, Argentina, Paraguai e Uruguai. P. tetraphylla é utilizada como tônica, em afecções estomacais, como sudorífera, anti-inflamatória, anti-helmíntica e inseticida. Esta planta é uma erva a subarbusto ereto que pode atingir 1 metro de altura. Suas inflorescências são terminais, em forma de cacho com flores amareladas. Os frutos são legumes do tipo sâmara de até 2,5 cm de comprimento. Foi verificada a presença de óleos voláteis, taninos, flavonóides e saponinas nas folhas, caules e flores. A análise morfológica foi efetuada em estereomicroscópio e a análise anatômica em secções paradérmicas e transversais com inclusão em hidroxietilmetacrilato. O estudo farmacobotânico conduzido demonstra que as folhas são caracteristicamente 4-folioladas, o folíolo mede de 0,5-1,2 cm de comprimento por 0,5-1,0 cm de largura e possui forma obovada. Possui cutícula lisa e plicada, presença de estômatos nas duas faces epidérmicas, células mucilaginosas, e falta de formações epicuticulares. O mesofilo assume padrão heterogêneo e assimétrico, o feixe vascular é do tipo colateral fechado. Estruturas secretoras são observadas na região distal da lâmina foliar e apresentam conteúdo de coloração azulesverdeada. O caule com até 1 m de altura e 0,15-0,40 cm de diâmetro, é caracteristicamente anguloso, estriado, glabro, esverdeado, pouco ramificado na base e com abundantes glândulas oblongas e translúcidas. A epiderme caulinar é uniestratificada, com cutícula espessa, estômatos evidentes, formações glandulares mucilaginosas arredondadas com conteúdo azulado e ausência de tricomas. O córtex é composto de 1 a 5 camadas de células parenquimáticas com variados tamanhos, o floema é protegido por uma camada de fibras esclerenquimáticas contendo até seis camadas, as quais apresentam-se na forma de anel interrompido envolvendo o sistema vascular. O cilindro central é do tipo sifonestólico contínuo ectofólico. A medula é composta por células parenquimáticas com espaços intercelulares do tipo meato, sem nenhum conteúdo interno. Estas singularidades morfoanatômicas são importantes e relevantes em trabalhos de farmacobotânica, pois em conjunto são usadas para estabelecer a autenticidade de diferentes espécies vegetais. A atividade anti-inflamatória do extrato hidroetanólico de P. tetraphylla foi avaliada através do modelo de indução da formação do tecido granulomatoso em ratos e dosagens séricas realizadas para verificação de toxicidade hepática e renal. Os animais tratados com extrato de P. tetraphylla apresentaram inibição do processo da inflamação de 31,20±4,71%, já o grupo tratado com nimesulida, padrão, mostrou uma inibição de 21,42±6,52%, quando comparados ao controle negativo propilenoglicol 20% (p<0,05). As dosagens séricas de AST, ALT e creatinina de todos os grupos, quando comparadas ao controle negativo, não apesentaram nenhuma elevação siginificativa. A atividade anti-inflamatória apresentada para o extrato de P. tetraphylla pode estar associada à sua composição que contém saponinas e flavonóides.

Texto completoThe study undertaken dealnig with a large genetical variability allowed the author to confirm the antinutritional effect of lucerne saponins on chickens. The varietal effects, sequence cropping, plant parts (leaves, stems, roots) have been analysed. The becoming of saponins during the industrial extraction process of proteins have been studied. The biological dosage methods available (Trichoderma, Tenebrio, hemolysis…) have been tried and compared : they are very well correlated and available for plant breeders to obtain genotypes with low content of saponins

Texto completoActivated Carbon Fibers (ACF) constitute a new class of activated carbon widely used for air or waste water treatment. Owing to their microporous structure and to their highly acidic characteristic, we were interested in applying them for the first time as acidic promoter in organic synthesis, notably for solvent free O- and Nglycosylation reactions. The goal of this work is to show the ability of ACF to replace harmful classical acidic catalysts (e. G. Lewis acid). On the basis of ACF characterization (determination of surface area by the Brunauer Emmett and Teller (BET) method, microporous volume by the Dubinin-Radushkevich equation, the surface acidity by Boehm methodology…) and studies on O- and N-glycosylation (effect of reactant concentrations, effect of reaction time and temperature, effect of the kind of reactant) hypothetic mechanisms are proposed, notably for the synthesis of saponin and nucleoside analogues

Texto completoThe introduction describes the principles of countercurrent chromatography and especially its centrifugal partition chromatography version, as long as new or to-come industrial apparatuses. Usual strategies for the solvent system choice in case of an elution development are compared. Principles and theory of the displacement mode are particularly developed in their solid-liquid and support-free versions. Personal work bears on several applications and betterments of both elution and displacement modes. In elution development, a saponin-containing extract of Bacopa monnieri, an Indian Ayurvedic plant, has been fractionated, and isolation of an hemisynthetic alkaloid is described. In displacement development, a new solvent system range is described for the pH-zone refining mode and applied to the purification at an actual preparative scale of galanthamine from Leucojum aestivum. A new type of ion-exchanger adapted to support-free chromatography is developed. Benzalkonium chloride is used as a strong cationic exchanger. A numerical model allows graphical simulations, and extensive experimental work is done on optimization of the method. Several applications of this development mode are described, one of them being purification of rosmarinic acid from Lavandula vera cell culture extract

Texto completoThe @chemical investigation of fruits and stem barks of Caryocar glabrum and Caryocar villosum, as well as leaves of Guioa crenulata led us to identify 76 compounds, 53 of which possess new structures. The isolated compounds belong to eight families of secondary metabolites: 54 saponins, 4 glycosides of benzylic or phenolic alcohols, 3 galloylhamameloses, 2 glycosides of 3,4-dihydroisocoumarin, 5 derivatives of ellagic acid, 3 flavonoids, 1 trimeric tannin formed by three epicatechinic units, and 4 glycosides of farnesol. Their structures were established by 1D and 2D NMR experiments, ESI-(MS)n and acid hydrolysis. In some cases, we have used circular dichroism to determine the configuration of asymmetric carbons. The influence of glucose and glucuronic acid on the hemolytic activity of saponins was evaluated. The toxic activity of methanol extracts of C. Glabrum and C. Villosum was evaluated by determination of lethal dose using brine shrimps (Artemia salina). The antiplasmodial activity of ethyl acetate extracts of fruits of C. Villosum and stem barks of C. Glabrum was measured. The dermocosmetic activity of some saponins which have hederagenin as aglycone, bidesmosides and galloylhamameloses was evaluated. The cytotoxic activity of ethanolic and ethyl acetate extracts of the leaves of Guioa crenulata was evaluated

Texto completoExtracts enrichided with saponins, obtained from stem barks of two Lecythidacaea, Foetidia africana and Bertholletia excelsa, showed an activity on human dermal fibroblasts in culture. The first extract stimulates the fibroblastic synthesis of GAG, and the second stimulates the synthesis of type I collagen. These activities should allow a dermocosmetic utilisation of the two extracts. In this work, we studied the chemical composition of these bioactive extracts. The chemical composition of a third species of Lecythidaceae, Planchonia grandis, was also studied. Structures of three prosapogenins, twenty-four saponins and three flavonoi͏̈ds, all newly described, were elucidated using mono and bidimensionnal NMR experiments and mass spectrometry ESI-(MS)n

Texto completoCentella asiatica is a herbaceous plant with great medicinal value, which has been used in traditional medicine as an antipyretic, diuretic and in the treatment of skin diseases. However, there is currently a shortage of "C. asiatica" in the international market, due to geopolitical problems and changes in the environment. An alternative source of centellosides, such as an in vitro biotechnology system, is therefore necessary. This thesis reports the development of a micropropagation system of "C. asiatica" using artificial seeds to obtain in vitro calli and subsequently cell suspensions. The results demonstrate that the organized structures of "C. asiatica" are not necessary for the synthesis of centellosides, its main active compounds. Moreover, the elicitation studies showed that exogenously applied methyl jasmonate induced the biosynthesis of saponins, while the free sterol content decreased notably, thus establishing a dose-dependent relationship between elicitor concentration and centelloside content.
Since the obtained cell suspension cultures of "C. asiatica" maintain active enzymatic systems, this has permitted the biotransformation of alpha-amyrin to centellosides. This process can become a alternative biotechnological system to produce saponins.

Texto completoThis work is dedicated to the application of high-performance thin-layer chromatography (HPTLC) for the analysis of plant extracts used in aroma, perfume and cosmetic industries. Different planar chromatographic methods were developed and validated for the quantification of natural compounds in plant matrices: quantification of nicotine in tobacco extracts, quantification of major phenolic compounds in vanilla fruits, beans and extracts and quantification of alcohols and acetates in vetiver extracts from Haiti. A fractionation scheme was developed for chemical separation of the metabolites in oleoresins; HPTLC, by its capacity to focus on specific metabolites, was used for phytochemical screening of the fractions. Fractionation of mate (Ilex paraguariensis St-Hil ) oleoresin allowed for the isolation of saponins enriched fraction which was characterized by HPTLC, HPLC-MS and NMR. 16 saponins were identified; 6 of them were never described in mate leaves. 4 genins were identified as to be ursolic, oleanolic and 23-hydroxyursolic acids as well as 3-hydroxy-24-nor-urs-4(23), 12-dien-28-oic acid, which was never documented. HPTLC and HPLC quantification allowed for the elucidation of 60 to 70 % of the extract and its valorization through its high content in polyphenols and saponins. Developed HPTLC methods were precise, sensitive and repeatable
