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). -
Diversification of Afrobatrachian Frogs and the Herpetofauna of the Arabian Peninsula
Diversification of Afrobatrachian Frogs and the Herpetofauna of the Arabian Peninsula By Daniel Portik A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Dr. Jimmy A. McGuire, Chair Dr. Rauri Bowie Dr. David Blackburn Dr. Rosemary Gillespie Fall 2015 Abstract Diversification of Afrobatrachian Frogs and the Herpetofauna of the Arabian Peninsula by Daniel Portik Doctor of Philosophy in Biology University of California, Berkeley Dr. Jimmy A. McGuire, Chair The identification of biotic and abiotic factors that promote the diversification of clades across Africa and the Arabian Peninsula remains a difficult challenge. A variety of ecological and evolutionary processes can be driving such patterns, and clade-specific traits may also play a role in the evolution of these groups. Comparative evolutionary studies of particular clades, relying on a phylogenetic framework, can be used to investigate many of these topics. Beyond these mechanisms there are abiotic factors, such as geological events, that can drive vicariance and dispersal events for large sets of taxa. The investigation of historical biogeography in a comparative phylogenetic framework can be used to detect such patterns. My dissertation explores these topics using reptiles and amphibians as study systems, and I rely on the generation of molecular sequence data, phylogenetics, and the use of comparative phylogenetic methods to address a variety of questions. I provide the abstract for each chapter below. Chapter 1: The reproductive modes of anurans (frogs and toads) are the most diverse among all the terrestrial vertebrates, and a major challenge is identifying selective factors that promote the evolution or retention of reproductive modes across clades. -

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. -

We explore the influence of each gene region on the support given to each node of the most parsimonious tree derived from a combined analysis of all three genes using Partitioned Bremer Support. We also explore the influence of assuming equal weights for all characters in the combined analysis by investigating the stability of clades to different transition/transversion weighting schemes. We find many strongly supported and stable clades in the Nymphalinae. We are also able to identify ‘rogue’ -
Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese -
Determining a Landscape Plant Database Matched to Hydrozones for South Africa

Hoy1*, Leslie R. Brown2, Richard M. Hendrick2 and Alan S. Barrett2 1Rand Water, PO Box 1127, Johannesburg, 2000, South Africa. 2Applied Behavioural Ecology and Ecosystems Research Unit, Department of Environmental Sciences, University of South Africa, Pretoria, South Africa. *E-mail: [email protected] Abstract About 27 % of available water in South Africa is utilised in the urban environment. Estimates for South Africa place ornamental landscape water use as high as 50 % of urban water use. South Africa’s average annual rainfall is approximately 495 mm. Rainfall patterns are erratic with periodic droughts of anticipated increased frequency. Ornamental landscapes require additional watering to minimise impacts of dry periods. These landscapes are often over- rather than under-watered. One method of reducing urban ornamental landscape water use is to group plants according to predefined hydrozones to optimise water use through improved site maintenance, landscape design and irrigation application. Currently no extensive researched database of commonly grown ornamental landscape plants linked to hydrozones exists for South Africa. To produce such a plant database, an analysis determining the hydrozone rating of plants sold in South African nurseries was undertaken. The result of this study is a database of plant species suitable for ornamental landscape hydrozones (high, medium, low and very low water requirements) and linked to a plant factor. This provides South African Green Industries Council members, especially landscapers with a database to assist in selecting the most appropriate plants for each hydrozone for their ornamental landscapes and gardens. -
