Berkheya Setifera DC Alfred Maroyi et al /J. Pharm. Sci. & Res. Vol. 11(8), 2019, 2942-2948 A review of botany, medicinal uses and biological activities of Berkheya setifera DC. (Asteraceae) Alfred Maroyi Medicinal Plants and Economic Development (MPED) Research Centre, Department of Botany, University of Fort Hare, Private Bag X1314, Alice 5700, South Africa Abstract Berkheya setifera is a well-known plant species in southern Africa in traditional and folk medicine. This study is aimed at providing a critical review of the botany, biological activities and medicinal uses of B. setifera. Documented information on botany, biological activities and medicinal uses of B. setifera was collected from several online sources which included BMC, Scopus, SciFinder, Google Scholar, Science Direct, Elsevier, Pubmed and Web of Science. Additional information on the botany, biological activities and medicinal uses of B. setifera was sourced from book chapters, books, journal articles, theses and scientific publications sourced from the University of Fort Hare library. The current study showed that the leaves and roots of B. setifera are traditionally used in 60% of the countries where the species is indigenous. Berkheya setifera is used as herbal medicine for 28 human diseases which include abdominal pains, arthritis, blood circulatory problems, colds, coughs, itching skin and rash, jaundice, kidney problems, magical uses, stomach complaints, sterility and uterine disorders. Pharmacological research revealed that B. setifera extracts have antibacterial, antimalarial, anti-inflammatory, antioxidant, haemolysis, antifungal and cytotoxicity properties. Future studies should concentrate on assessing the phytochemical, pharmacological and toxicological activities of B. setifera crude extracts as well as chemical ingredients isolated from the species. Keywords: Berkheya setifera, Compositae, herbal medicine, indigenous pharmacopeia, pharmacology, phytochemistry INTRODUCTION Taxonomy and botanical description of Berkheya Berkheya setifera DC. is a perennial herbaceous plant setifera belonging to Compositae or the Asteraceae family. Research by Phaliso et al.8 revealed that genus Berkheya Berkheya setifera together with other related species such Ehrhart consisting of about 80 species is paraphyletic with as B. echinacea (Harv.)

Box 722, Somerset West 7129, South Africa Department of Chemistry, The University of Adelaide, Adelaide, Australia 1 ABSTRACT Aims There are major knowledge gaps in understanding the translocation leading from nickel uptake in the root to accumulation in other tissues in tropical nickel hyperaccumulator plant species. This study focuses on two species, Rinorea cf. bengalensis and Rinorea cf. javanica and aims to elucidate the similarities and differences in the distribution of nickel and physiologically relevant elements (potassium, calcium, manganese and zinc) in various organs and tissues. Methods High-resolution X-ray fluorescence microscopy (XFM) of frozen-hydrated and fresh- hydrated tissue samples and nuclear microprobe (micro-PIXE) analysis of freeze-dried samples were used to provide insights into the in situ elemental distribution in these plant species. Results This study has shown that the distribution pattern of nickel hyperaccumulation is typified by very high levels of accumulation in the phloem bundles of roots and stems.

[email protected] (author for correspondence) 2 Department of Botany, University of Hawaii at Manoa, Hawaii 96822, U.S.A. [email protected]; ster- ling@hawaii. edu Compositae (Asteraceae) are the largest flowering plant family (23,000 to 30,000 species) and its members are found throughout the world in both temperate and tropical habitats. The subfamilies and tribes of Compositae remained relatively constant for many years; recent molecular studies, however, have identified new subfa- milial groups and identified previously unknown relationships. Currently there are 35 tribes and 10 subfami- lies (Baldwin & al., 2002; Panero & Funk, 2002). Some of the tribes and subfamilies have not been tested for monophyly and without a clear understanding of the major genera that form each tribe and subfamily, an accu- rate phylogeny for the family cannot be reconstructed. The tribe Arctoteae (African daisies) is a diverse and interesting group with a primarily southern African distribution (ca. 17 genera, 220 species). They are espe- cially important in that most of the species are found in the Cape Floral Kingdom, the smallest floral kingdom and the subject of intense conservation interest. Arctoteae are part of the monophyletic subfamily Cichorioideae s.s. Other tribes in the subfamily include Eremothamneae, Gundelieae, Lactuceae, Liabeae, Moquineae, and Vernonieae, and these were all evaluated as potential outgroups.

  • Kirstenbosch NBG List of Plants That Provide Food for Honey Bees
    Indigenous South African Plants that Provide Food for Honey Bees Honey bees feed on nectar (carbohydrates) and pollen (protein) from a wide variety of flowering plants. While the honey bee forages for nectar and pollen, it transfers pollen from one flower to another, providing the service of pollination, which allows the plant to reproduce. However, bees don’t pollinate all flowers that they visit. This list is based on observations of bees visiting flowers in Kirstenbosch National Botanical Garden, and on a variety of references, in particular the following: Plant of the Week articles on www.PlantZAfrica.com Johannsmeier, M.F. 2005.
