    The structure and synthesis of trimeric and related dimeric Proteracacinidins from Acacia heteroensis. 

    Fourie, Eleanor (University of the Free State, 2002-07)
    English: The presence of 4', 7,8-trihydroxyl substituted flavanoids in plant material is limited to Acacia galpinii and Acacia caffra in Southern Africa. The existence of pyrogallol-type A-ring oligomers in these trees was ...

    Sintese en struktuur van Pirano-isoflavanoïede 

    Van Heerden, Fanie Retief (University of the Free State, 1977-01)
    Afrikaans: Die medisinale gebruik (waarskynlik as antiseptikum) van die bas van Dalbergia nitidula Welw. ex Bak. (Leguminosae) deur inboorlinge het tot die huidige chemiese ondersoek aanleiding gegee. Hierdie ondersoek ...

    An investigation into the biocatalytic and antimicrobial properties of Eucomis autumnalis Mill. bulbs 

    Craven, Pieter (University of the Free State, 2003)
    English: Over the past number of years a renewed interest in the search for natural alternative products, with the aim to replace existing synthetic antimicrobial, herbicidal and pesticidal chemicals in organic crop ...

    Development of new "green" methodology for the synthesis of substituted phenylacetic acid derivatives as precursors to isoflavonoids and related compounds 

    Pieterse, Tanya (University of the Free State, 2013-01)
    English: Flavonoids and isoflavonoids are known to exhibit many important physiological properties and are especially promising candidates for cancer chemoprevention. Similar to most natural products, studies directed at ...

    Identification and expression analysis of flavonoid biosynthetic genes in the genus Clivia 

    Snyman, Marius Christian (University of the Free State, 2010)
    English: Anthocyanins belong to a large group of secondary plant metabolites, the flavonoids, and fulfil a range of biological functions that include the cyanic pigmentation they provide to flowers, fruits, vegetables and ...

    Photochemistry of (+)-catechin and (-)-epicatechin 

    Wilhelm, Anke (University of the Free State, 2008-01)
    Despite the well known fact that photolysis of free phenolic catechins give rise to isomerisation at the C-2 position (e.g. (-)-cis epicatechin converts to the sterically less hindered (-)-trans isomer), researchers have ...

    Development of a viable protocol aimed at the synthesis of a selected natural product with possible application in the industry 

    Jordaan, Lizette (University of the Free State, 2007)
    Since the introduction of synthetic analogues in both the health-related and cosmetic industry, a new generation has emerged in search of beneficial bioactivity compounds. This generation of “natural and green” focuses ...

    Studies directed at the stereoselective synthesis of flavonoids through the hydrogenation of prochiral precursors 

    Van Tonder, Johannes Henning (University of the Free State, 2008-11)
    English: The in vitro studies of biologically active flavonoids are hampered by the inaccessibility of all monomeric units in enantiomerically pure form. Although a number of these scalemic flavonoids can be obtained ...

    Development of methodology for the synthesis of 4-arylflavan-3-ol lactones 

    Van Tonder, Bernadette (University of the Free State, 2008-05)
    English: The phenolic content of the heartwood of Peltophorum africanum (African wattle) and Burkea africanum (Red syringa) proved to contain a variety of compounds including the novel 4-arylflavan-3-ol lactones, ...
