Chouana, Toufik. "Caractérisation structurale et activités biologiques des polysaccharides d'Astragalus gombo bunge". Thesis, Université Clermont Auvergne (2017-2020), 2017. http://www.theses.fr/2017CLFAC112/document.
Pełny tekst źródłaAstragalus gombo Bunge (Fabaceae) is a terrestrial plant occuring in the East Septentrional Sahara (Ouargla, Algeria). It is commonly used as fodder or in traditional medicine by local populations. Despite numerous publications focusing on polysaccharidic contents of Astragalus species and the designation of their putative or proved biological activities, no study has examined those of A. gombo. The objective of this thesis was firstly to investigate several organs of this plant for their polysaccharide contents. In a second step, the biological and rheological properties of these biopolymers have been studied to identify ways of adding value. Results led to the identification of pectic compounds and hemicelluloses in the rods of Astragalus gombo whereas a galactomannan was detected in its seeds. This galactomannan was a high molecular weight macromolecule composed of a β-(1→4)-D-mannan skeleton ramified by residues of D-galactopyranoses. The M/G ratio was of 1.7. The characterization of its rheological behavior was typic of that of a rheofluidifiant fluid with viscoelastic properties. The study of its biological properties showed its potential as prebiotic and antioxidant agent

-F(GAA) (trnL-F intergenic spacer), trnV intron, matK (maturase kinase) cpDNA (chloroplast) and ITS (internal transcribed spacer) nDNA (nuclear) regions. Fifty-six Astragalus species with their replicas and one Cicer species as outgroup were analyzed by polymerase chain reaction amplification and DNA sequencing methods. Eleven unknown samples were also used in the current study to understand their section and species name. The results of the study indicated that unknown A35 and A52 samples could be named as A. dasycarpus, while unknown A65 and A66 samples as A. ovatus and lastly unknown A2 sample as A. nitens or A. aucheri. Section of unknown A3, A16, A20, A108, A109 and A110 samples were determined as Incani, but the exact species identification of these samples were not possible because of their close phylogenetic associations with more than one species. Highest genetic diversity was observed when the DNA sequences of ITS nrDNA (nuclear ribosomal) region comprising three subregions as ITS1, 5.8S and ITS2 was used, while the lowest one was calculated when DNA sequence of trnL-F cpDNA region was analyzed. The genetic divergence between Incani and Dissitiflori sections was highest whereas between Hypoglottidei and Dissitiflori was lowest based on all used regions. To figure out phylogenetic relationships among Astragalus species distributed in Turkey and in other regions of the World, DNA sequences of studied regions of foreign samples were collected from the NCBI database and were evaluated with DNA sequence of Turkish species used in the curent study. The Iranian samples either scattered in the phylogenetic tree or attached to our samples externally. South and North American samples (New World Astragalus or Neo Astragalus group) were nested within a different subcluster, which was located in the main cluster produced by samples of Old World Astragalus group (Turkish samples). With these results, we can say that New World Astragalus group is monophyletic and diverged from Old World Astragalus group. Evolutionary divergence time for Astragalus genus was estimated as about 12.5 - 14.5 million years (Ma), and that of New World Astragalus group as 5.0 - 4.0 Ma when rates of nucleotide substitutions of trnL intron and matK cpDNA regions were analyzed. In addition to evolutionary divergence time estimation for Astragalus and New World Astragalus group, divergence times among used three sections of the genus were also calculated by using DNA sequences of trnL, trnV intron and matK cpDNA regions and results indicated that Hypoglottidei and Dissitiflori sections diverged about 5.0-7.0 million years later than Incani section.

Pełny tekst źródłaThe genus Astragalus L. (Fabaceae) is one of the genera with the largest number of representatives among the angiosperms. Its center of origin and diversity is located in the arid mountains of Central and Southwest Asia. In Lebanon, this genus is also one of the most represented genera in the flora, with 62 species and subspecies and 22 endemic species identified. The different taxa of this genus are difficult to identify based only on morphological characters and their current status of distribution must be evaluated. Phylogenetic relationships, changes in genome size and the role of polyploidy in the evolution of Astragalus genus in the Lebanese mountains range were studied. Our data confirm that a significant interspecific chromosomal polymorphism exists in the genus Astragalus of Lebanon and polyploidy and the subsequent evolution of the genome may be important drivers of the evolution of this genus. The diversification process of Astragalus genus that took place in Lebanon was analyzed using phylogenetic and molecular dating methods and analysis of ancestral areas. Our results confirm that Lebanon is the third center of diversity and should be considered as a "cradle" of biodiversity. Therefore, this study is a contribution to a better understanding of evolutionary and biogeographic processes behind the development of biodiversity in Lebanon, with an applied purpose of biogeographic conservation

Pełny tekst źródłaThe present study, concerning three species of Glycyrrhiza (G. Echinata, G. Glabra –truth liquorice, G. Lepidota) and A. Glycyphyllos (falsehood liquorice) has permitted at different levels (species, populations, individuals, organs) to show and study two types of variations: karyotypical (for example, possible existence of chromosomical mosaic in some individual of A. Glycyphyllos) and morphological (speed and intensity of this developmental heterophylly, phenomenon of rejuvenation accompanied by ramification). The synthesis of our results has allowed us to order the species from the less to the more developed: G. Lepidota, G. Glabra, G. Echinata and A. Glycyphyllos. More fundamentally, the study of the speed and diversity of developmental heterophylly sequence has been shown of great relevance to taxonomic and phylogenic research

Pełny tekst źródłaPlants belonging to the legume family have a big economic interest, being Brazil is a country with extensive use of plants in this family. In this context, we highlight the legume Phaseolus vulgaris L. popularly known as beans, which are a good source of bioactive compounds. This species is native of southern Brazil and the main food consumed by the population. In its chemical composition can meet the flavonoids. Numerous scientific articles describing the activities of flavonoids as antioxidants, antimutagênic, anticarcinogenic and nitrogen uptake during plant development. Since this is a legume consumed more food in the world and of great economic importance, this study sought to evaluate the chromatographic profile of the methanol extract of 47 cultivars of beans through the technique of High Performance Liquid Chromatography (HPLC) and also the validation of their method. The plant material, seeds, water content was established by gravimetric method. Through the chromatographic profile of the seeds of bean cultivars, it was possible to identify the presence of flavonoids and astragalin, a kaempferol heteroside. The method was validated for High Performance Liquid Chromatography (HPLC) according to the methods suggested in the literature. The cultivars with colored TB 0224, TB0226, TB 0309, Rosinha Precoce and Amarelo Iolanda, were those with a higher content of astragalin, demonstrating that colored beans have a higher composition of astragalin.

The species that was identified as the cause of these problems is A. distihens, but A. bergii has been included because both species share the same distribution area and also because both of them are quite similar. The search for its toxic compounds was done on the basis of the information reviewed, that they havehydrocianic acid, saponins and selenium. Also aliphatic nitrocompounds, that were identified in various Astragalus species from abroad, were included.

The purposes of this study were to investigate antioxidative components from seeds of Astragalus complantus and flowers of Lanata camara and volatile components from seeds of Astragalus complantus. The results were summerized as following: (1) The antioxidative components from the ethyl acetate extract of seeds of Astragalus complantus The ground powder of seeds of Astragalus complantus was extracted with methanol . Then the methanol extract was extracted with n-hexane, ethyl acetate and n-butanol in succession. The antioxidative activity of the extracts was measured by the ferric thiocyanate method. The antioxidative efficiency was found in following order : BHA>ethyl acetate extract>n-butanol extract>α-tocopherol>n-hexane extract>control. The ethyl acetate extract was fractionated by various chromatographies to isolate three pure components. Two of the isolated components were identified to be 3,5-dihydroxy-4''-methoxy- 1,1''-(1''2-ethylenediyl) bis[benzene] and 6''-methoxy-7-methyl formononetin (7,4'',6''-trimethoxy isoflavone) respectively.The rest one was tentatively concluded to be p-coumaroyl triterpenoid ester. (2) The antioxidative components from the ethyl acetate extract of flower of Lanata camara The flowers of Lanata camara were extractd with n-hexane, ethyl acetate, chloroform and methanol in order. The antioxidative activity of extracts were measured by the ferric thiocyanate method. The antioxidative efficiency was found in following order : BHA>ethyl acetate extract>α-tocopherol>n-hexane extract>methanol extract>chloroform extract>control. The ethyl acetate extract was fractionated by various chromatographies to isolate two pure polyphenyl. They were identified to be 2''-(3",4",5"- trihydroxyphenyl)-ethyl -sterate and protocatechuic acid respectively. (3)Volatile components from seeds of Astragalus complantus The volatile extracts were obtained from seeds of Astragalus complantus by Likens-Nickerson extraction, supercritical fluid extraction (SFE) and the ethyl acetate extract. The 28 components of the volatile extracts had been identified by GC-MS,including 5 alkylenes, 5 aldehydes, 5 ketones, 5 acids, 3 esters and 1 alkane. The antioxidative activities of the volatile extracts and solvents extracts were analyzed by the ferric thiocyanate method and compared to that of BHA and α-tocopherol. The antioxidative activity of the ethyl acetate extraction was found to be better than those of Likens-Nickerson extraction and supercritical fluid extraction.
