    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Vanguerieae; Rubiacaeae; phylogeny; classification; morphology; ITS; trnT-F; rpl16; Biologi; Biology; Biologi; systematisk botanik; Systematic Botany;

    Sammanfattning : Vanguerieae is a tribe in the mainly tropical angiosperm family Rubiaceae. The tribe currently comprises around 600 species in 27 genera, with the major part of the species distributed in Africa south of the Sahara. The phylogeny of the tribe was investigated using both molecular and morphological data. LÄS MER

  3. 2. Phylogenetic and taxonomic studies in the tribe Antirrhineae (Scrophulariaceae) with special reference to the genera Kickxia and Nanorrhinum

  4. 3. Antiparasitic metabolites from plants used in the Tacana Bolivian native tribe : Traditional medicine, an overview of natural products with medicinal interest

    Författare :Ivan Limachi; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tacana Traditional Medicine; Antiparasitic; cytotoxicity; Hyptis brevipes; hyptis mutabilis; Tessaria integrifolia; Trichilia adolfi;

    Sammanfattning : The thesis aims to contribute to the preservation of traditional medicinal knowledge of the Tacana Bolivian native tribe, as well as to the isolation and characterization of antiparasitic metabolites from plants used for the treatment of endemic diseases. A selection of medicinal plants, made in collaboration with the Tacana communities who decided which plants have a specific medicinal propose, were collected and identified by the national herbarium of Bolivia, and confirmed by healers from the most representative communities.
