Literary Histories

Despite many efforts to publish comprehensive literary histories of South or Southern Africa in recent years, few studies existin which a thorough comparative study is undertaken between two or more South African literatures. This article wants to provide a practical example of such a study by comparing the urbanisation of Afrikaners in Afrikaans literature with that of black people as seen in English and Zulu literature. The statement made by Ampie Coetzee that comparative studies should take place within the framework of discursive formations is one of the fundamental starting points of this study. Maaike Meijer’s concept of the “cultural text” is further employed as a theoretical instrument. The identification of repeating sets of representation is central to the demarcation of a “cultural text about urbanisation” in Afrikaans, English and Zulu literature respectively. The cultural text forms the basis from which a valid comparative study can be embarked upon, and the results of the research have important implications for further comparative studies but also literary historiography.

Identification And Quantification

In this work, we report the identification and quantification of catechins by electrochemistry and UV-Vis spectroscopy in Elephantorrhiza elephantina (Fabaceae) and Pentanisia prunelloides (Rubiaceae), both of which are medicinal plants that are widely used in Southern Africa to remedy various ailments. A comparative study of the catechin content as (-)-epicatechin equivalent is reported for the first time, with E. elephantina exhibiting a higher concentration relative to P. prunelloides in both aqueous and methanol extracts.
