    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 ...

    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 ...

    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 ...
