Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi
YIKA-VWAZA TRUST RESEARCH STUDY REPORT N (2017/18) Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi By Sopani Sichinga ([email protected]) September , 2019 ABSTRACT In 2018 – 19, a survey on vascular plants was conducted in Vwaza Marsh Wildlife Reserve. The reserve is located in the north-western Malawi, covering an area of about 986 km2. Based on this survey, a total of 461 species from 76 families were recorded (i.e. 454 Angiosperms and 7 Pteridophyta). Of the total species recorded, 19 are exotics (of which 4 are reported to be invasive) while 1 species is considered threatened. The most dominant families were Fabaceae (80 species representing 17. 4%), Poaceae (53 species representing 11.5%), Rubiaceae (27 species representing 5.9 %), and Euphorbiaceae (24 species representing 5.2%). The annotated checklist includes scientific names, habit, habitat types and IUCN Red List status and is presented in section 5. i ACKNOLEDGEMENTS First and foremost, let me thank the Nyika–Vwaza Trust (UK) for funding this work. Without their financial support, this work would have not been materialized. The Department of National Parks and Wildlife (DNPW) Malawi through its Regional Office (N) is also thanked for the logistical support and accommodation throughout the entire study. Special thanks are due to my supervisor - Mr. George Zwide Nxumayo for his invaluable guidance. Mr. Thom McShane should also be thanked in a special way for sharing me some information, and sending me some documents about Vwaza which have contributed a lot to the success of this work. I extend my sincere thanks to the Vwaza Research Unit team for their assistance, especially during the field work. -
Diabetes and Medicinal Plants: a Literature Review
ISOLATION AND IDENTIFICATION OF ANTIDIABETIC COMPOUNDS FROM BRACHYLAENA DISCOLOR DC Thesis submitted in fulfilment of the requirements for the degree Master of Science By Sabeen Abdalbagi Elameen Adam School of Chemistry and Physics University of KwaZulu-Natal Pietermaritzburg Supervisor: Professor Fanie R. van Heerden August 2017 ABSTRACT Diabetes mellitus, which is a metabolic disease resulting from insulin deficiency or diminished effectiveness of the action of insulin or their combination, is recognized as a major threat to human life. Using drugs on a long term to control glucose can increase the hazards of cardiovascular disease and some cancers. Therefore, there is an urgent need to discover new, safe, and effective antidiabetic drugs. Traditionally, there are several plants that are used to treat/control diabetes by South African traditional healers such as Brachylaena discolor. This study aimed to isolate and identify antidiabetic compounds from B. discolor. The plant materials of B. discolor was collected from University of KwaZulu-Natal botanical garden. Plant materials were dried under the fume hood for two weeks and ground to a fine powder. The powder was extracted with a mixture of dichloromethane and methanol (1:1). To investigate the antidiabetic activity, the prepared extract was tested in vitro for glucose utilization in a muscle cell line. The results revealed that blood glucose levels greater than 20 mmol/L, which measured after 24 and 48 hours of the experimental period, three fractions had positive (*p<0.05) antidiabetic activity compared to the control. The DCM:MeOH (1:1) extract of B. discolor leaves was subjected to column chromatography, yielding five fractions (A, B, C, D, and E). -
Brachylaena Elliptica and B. Ilicifolia (Asteraceae): a Comparative Analysis of Their Ethnomedicinal Uses, Phytochemistry and Biological Activities
Journal of Pharmacy and Nutrition Sciences, 2020, 10, 223-229 223 Brachylaena elliptica and B. ilicifolia (Asteraceae): A Comparative Analysis of their Ethnomedicinal Uses, Phytochemistry and Biological Activities Alfred Maroyi* Department of Botany, University of Fort Hare, Private Bag X1314, Alice 5700, South Africa Abstract: Brachylaena elliptica and B. ilicifolia are shrubs or small trees widely used as traditional medicines in southern Africa. There is need to evaluate the existence of any correlation between the medicinal uses, phytochemistry and pharmacological properties of the two species. Therefore, in this review, analyses of the ethnomedicinal uses, phytochemistry and biological activities of B. elliptica and B. ilicifolia are presented. Results of the current study are based on data derived from several online databases such as Scopus, Google Scholar, PubMed and Science Direct, and pre-electronic sources such as scientific publications, books, dissertations, book chapters and journal articles. The articles published between 1941 and 2020 were used in this study. The leaves and roots of B. elliptica and B. ilicifolia are mainly used as a mouthwash and ethnoveterinary medicines, and traditional medicines for backache, hysteria, ulcers of the mouth, diabetes, gastro-intestinal and respiratory problems. This study showed that sesquiterpene lactones, alkaloids, essential oils, flavonoids, flavonols, phenols, proanthocyanidins, saponins and tannins have been identified from aerial parts and leaves of B. elliptica and B. ilicifolia. The leaf extracts and compounds isolated from the species exhibited antibacterial, antidiabetic, antioxidant and cytotoxicity activities. There is a need for extensive phytochemical, pharmacological and toxicological studies of crude extracts and compounds isolated from B. elliptica and B. ilicifolia. -
A Classification of the Subtropical Transitional Thicket in the Eastern Cape, Based on Syntaxonomic and Structural Attributes
S. Afr. J. Bot., 1987, 53(5): 329 - 340 329 A classification of the subtropical transitional thicket in the eastern Cape, based on syntaxonomic and structural attributes D.A. Everard Department of Plant Sciences, Rhodes University, Grahamstown, 6140 Republic of South Africa Accepted 11 June 1987 Subtropical transitional thicket, traditionally known as valley bushveld, covers a significant proportion of the eastern Cape. This paper attempts to classify the subtropical transitional thicket into syntaxonomic and structural units and relate it to other thicket types on a continental basis. Twelve sites along a rainfall gradient were sampled for floristic and structural attributes. The floristic data were classified using TWINSPAN. Results indicate that the class subtropical transitional thicket has at least two orders of vegetation, namely kaffrarian thicket and kaffrarian succulent thicket. Two forms of thicket were recognized for both these orders viz. mesic kaffrarian thicket and xeric kaffrarian thicket for the kaffrarian thicket and mesic succulent thicket and xeric succulent thicket for the kaffrarian succulent thicket. Ordination of site data by DECORANA grouped sites according to these vegetation categories and in a sequence along axis 1 to which the rainfall gradient can be clearly related. Variation within the mesic kaffrarian thicket was however greater than between some of the other thicket types, indicating that more data are required before these forms of thicket can be formalized. Composition, endemism, diversity and the environmental controls on the distribution of the thicket types are discussed. 'n Aansienlike gedeelte van die Oos-Kaap word beslaan deur subtropiese oorgangsruigte, wat tradisioneel as valleibosveld bekend is. Hierdie studie is 'n poging om subtropiese oorgangsruigte in sintaksonomiese en strukturele eenhede te klassifiseer en dit op 'n kontinentale basis in verband met ander ruigtetipes te bring. -

City of Cape Town | Table Bay Nature Reserve | Quarterly Report | January to March 2014 1 1 AREA MANAGER’S SECTION 1.1 Typha capensis (bulrush) reeds Numerous communications have been received from neighbours around the Table Bay Nature Reserve about Typha capensis (bulrush) reeds and the seeds that they release during February and March. From the 1950s to 1980s there were several drastic alterations to the hydrology of the wetlands in the Table Bay area, including major excavations and dredging, construction of major roads and railways, and the development of residential and industrial areas. Today these developments and roads act as drainage impoundments. Surface storm-water runoff and treated wastewater effluent is directed into the natural areas. This is changing the dynamic seasonal and temporary wetlands into more static nutrient-enriched permanent water areas. As a result of this urbanisation, elevated water and nutrient levels are more likely to persist throughout the Rietvlei wetland system. -
Exploring the Benefits and Challenges of Indigenous Foods in an African Context Using a Case Study of Community Gardens in the Western Cape of South Africa
Exploring the benefits and challenges of indigenous foods in an African context using a case study of community gardens in the Western Cape of South Africa by Francia-Marié de Bruin Thesis presented in partial fulfilment of the requirements for the degree Of Master of Philosophy in Sustainable Development in the Faculty of Economic and Management Sciences at Stellenbosch University Supervisor: Dr Laura Pereira Co-Supervisor: Catherine (Loubie) Rusch March 2018 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third-party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: March 2018 Copyright © 2018 Stellenbosch University All rights reserved i | P a g e Stellenbosch University https://scholar.sun.ac.za Abstract Research suggests that the benefits and value of indigenous foods within the South African context have not been fully utilised. Their potential value to the South African food system and food security which is embedded within it, could be enhanced were their benefits to be explored more comprehensively. Therefore, the aim of this research was to systematically review literature using relevant search criteria and databases relating to underutilised indigenous crop species and foods in Africa as well as abroad (including the Oceania, South America and Asia). The intention was to provide an encompassing overview of both literature and literature gaps regarding nutritional, environmental, economic, and social-cultural benefits and challenges of indigenous food plants. -

Wang1,2, G.Q. Li1, Q.L. Liu1, S.F. Chen1,2 Key words Abstract Plantation-grown Eucalyptus (Myrtaceae) and other trees residing in the Myrtales have been widely planted in southern China. These fungal pathogens include species of Cryphonectriaceae that are well-known to cause stem Eucalyptus and branch canker disease on Myrtales trees. During recent disease surveys in southern China, sporocarps with fungal pathogen typical characteristics of Cryphonectriaceae were observed on the surfaces of cankers on the stems and branches host jump of Myrtales trees. In this study, a total of 164 Cryphonectriaceae isolates were identified based on comparisons of Myrtaceae DNA sequences of the partial conserved nuclear large subunit (LSU) ribosomal DNA, internal transcribed spacer new taxa (ITS) regions including the 5.8S gene of the ribosomal DNA operon, two regions of the β-tubulin (tub2/tub1) gene, plantation forestry and the translation elongation factor 1-alpha (tef1) gene region, as well as their morphological characteristics. The results showed that eight species reside in four genera of Cryphonectriaceae occurring on the genera Eucalyptus, Melastoma (Melastomataceae), Psidium (Myrtaceae), Syzygium (Myrtaceae), and Terminalia (Combretaceae) in Myrtales. These fungal species include Chrysoporthe deuterocubensis, Celoporthe syzygii, Cel. eucalypti, Cel. guang dongensis, Cel. cerciana, a new genus and two new species, as well as one new species of Aurifilum. These new taxa are hereby described as Parvosmorbus gen. -
