Antioxidant and Acetylcholinesterase-Inhibitory Properties of Long-Term Stored Medicinal Plants Stephen O Amoo, Adeyemi O Aremu, Mack Moyo and Johannes Van Staden*
Amoo et al. BMC Complementary and Alternative Medicine 2012, 12:87 http://www.biomedcentral.com/1472-6882/12/87 RESEARCH ARTICLE Open Access Antioxidant and acetylcholinesterase-inhibitory properties of long-term stored medicinal plants Stephen O Amoo, Adeyemi O Aremu, Mack Moyo and Johannes Van Staden* Abstract Background: Medicinal plants are possible sources for future novel antioxidant compounds in food and pharmaceutical formulations. Recent attention on medicinal plants emanates from their long historical utilisation in folk medicine as well as their prophylactic properties. However, there is a dearth of scientific data on the efficacy and stability of the bioactive chemical constituents in medicinal plants after prolonged storage. This is a frequent problem in African Traditional Medicine. Methods: The phytochemical, antioxidant and acetylcholinesterase-inhibitory properties of 21 medicinal plants were evaluated after long-term storage of 12 or 16 years using standard in vitro methods in comparison to freshly harvested materials. Results: The total phenolic content of Artemisia afra, Clausena anisata, Cussonia spicata, Leonotis intermedia and Spirostachys africana were significantly higher in stored compared to fresh materials. The flavonoid content were also significantly higher in stored A. afra, C. anisata, C. spicata, L. intermedia, Olea europea and Tetradenia riparia materials. With the exception of Ekebergia capensis and L. intermedia, there were no significant differences between the antioxidant activities of stored and fresh plant materials as measured in the β-carotene-linoleic acid model system. Similarly, the EC50 values based on the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay were generally lower for stored than fresh material. Percentage inhibition of acetylcholinesterase was generally similar for both stored and fresh plant material.

DETECTION OF SELECTIVE TYROSINASE INHIBITORS FROM SOME SOUTH AFRICAN PLANT EXTRACTS OF LAMIACEAE FAMILY By Ninon Geornest Eudes Ronauld ETSASSALA A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science Department of Chemistry Faculty of Natural Sciences University of the Western Cape Supervisor: Dr. Ahmed Mohammed Co-supervisor: Prof. Emmanuel Iwuoha AUGUST 2016 ABSTRACT ABSTRACT Various dermatological disorders, such as formation of black pigmented patches on the surface of the skin arise from the over-activity of tyrosinase enzyme’s degenerative action. This enzyme is further implicated in the involvement of melanin in malignant melanoma, the most life- threatening skin tumors. Although, synthetic products were found effective to combat this menace, nevertheless, overtime detrimental effect on human skin is a challenge. Investigation of natural tyrosinase inhibitors from methanol extracts of medicinal plants of Lamiaceae family using L-tyrosine as substrate on three different complementary assays (TLC bio-autography, spectrophotometry and cyclic voltammetry) was carried out accordingly. The result indicated Salvia chamelaeagnea, Salvia dolomitica, Plectranthus ecklonii, Plectranthus namaensis, and Plectranthus zuluensis, with significant zone of inhibition against tyrosinase on TLC bio-autography, spectrophotometry result showed that extracts of Plectranthus ecklonii (IC50 = 21.58 휇g/mL), Plectranthus zuluensis (IC50 = 23.99 휇g/mL), Plectranthus madagascariensis (IC50 = 23.99 휇g/mL) and Salvia lanceolata (IC50 = 28.83) demonstrated good anti-tyrosinase activity when compared with kojic acid (IC50 = 3.607 μg/mL). On the other hand, cyclic voltammetry are in consonant with above results thereby supported the nomination of some of the extracts as strong anti-tyrosinase agents.

The Potential of South African Plants in the Development of New Medicinal Products ⁎ B.-E
Available online at www.sciencedirect.com South African Journal of Botany 77 (2011) 812–829 www.elsevier.com/locate/sajb Review The potential of South African plants in the development of new medicinal products ⁎ B.-E. Van Wyk Department of Botany and Plant Biotechnology, University of Johannesburg, P.O. Box 524, Auckland Park 2006, South Africa Received 2 July 2011; received in revised form 26 August 2011; accepted 26 August 2011 Abstract Southern Africa is an important focal point of botanical and cultural diversity but only a few plant species have hitherto become fully commer- cialised as medicinal products. In recent years there has been an upsurge in research and development activity, resulting in several new products and new crops. In this review, more than 90 of the best-known and most promising indigenous South African plants are listed and subjectively evaluated in the context of their potential for commercialisation as medicinal products for a variety of applications. The history of product devel- opment relating to the following species is brieﬂy discussed and the plants and some of their products are illustrated: Agathosma betulina (buchu), Aloe ferox (bitter aloe), Artemisia afra (African wormwood), Aspalathus linearis (rooibos tea), Bulbine frutescens (burn jelly plant); Cyclopia gen- istoides (honeybush tea), Harpagophytum procumbens (devil's claw), Hoodia gordonii (hoodia, ghaap), Hypoxis hemerocallidea (“African pota- to”), Lippia javanica (fever tea), Mesembryanthemum tortuosum (=Sceletium tortuosum)(kanna, kougoed), Pelargonium sidoides (“Umckaloabo”), Siphonochilus aethiopicus (African ginger), Sutherlandia frutescens (=Lessertia frutescens) (cancer bush), Warburgia salutaris (pepperbark tree) and Xysmalobium undulatum (“Uzara”). The main factors that are apparently responsible for failure or success will be highlight- ed, especially the importance of marketing strategy, proof of concept and barriers to market entry.

The Botanical, Chemical and Ethnobotanical Diversity of Southern African Lamiaceae
molecules Review The Botanical, Chemical and Ethnobotanical Diversity of Southern African Lamiaceae Ryan D. Rattray and Ben-Erik Van Wyk * Department of Botany and Plant Biotechnology, University of Johannesburg, Auckland Park, P.O. Box 524, Johannesburg 2006, South Africa; [email protected] * Correspondence: [email protected]; Tel.: +27-11-559-2412 Abstract: The Lamiaceae is undoubtedly an important plant family, having a rich history of use that spans the globe with many species being used in folk medicine and modern industries alike. Their ability to produce aromatic volatile oils has made them valuable sources of materials in the cosmetic, culinary, and pharmaceutical industries. A thorough account of the taxonomic diversity, chemistry and ethnobotany is lacking for southern African Lamiaceae, which feature some of the region’s most notable medicinal and edible plant species. We provide a comprehensive insight into the Lamiaceae ﬂora of southern Africa, comprising 297 species in 42 genera, 105 of which are endemic to the subcontinent. We further explore the medicinal and traditional uses, where all genera with documented uses are covered for the region. A broad review of the chemistry of southern African Lamiaceae is presented, noting that only 101 species (34%) have been investigated chemically (either their volatile oils or phytochemical characterization of secondary metabolites), thus presenting many and varied opportunities for further studies. The main aim of our study was therefore to present an up-to-date account of the botany, chemistry and traditional uses of the family in southern Africa, and Citation: Rattray, R.D.; Van Wyk, to identify obvious knowledge gaps.

Recently, a study showed that T. riparia essential oil (TrEO) obtained in summer has antileishmanial effects, although these results could be influenced by seasonal variation. This study evaluated the activity of the TrEO obtained in different seasons against Leishmania (Leishmania) amazonensis, in vitro and in vivo. The compounds in the TrEO were analysed by gas chromatography-mass spectrometry; terpenoids were present and oxygenated sesquiterpenes were the majority compounds (55.28%). The cytotoxicity and nitric oxide (NO) production were also tested after TrEO treatment. The TrEO from all seasons showed a 50% growth inhibitory concentration for promastigotes of about 15 ng/mL; at 30 ng/mL and 3 ng/mL, the TrEO reduced intracellular amastigote infection, independently of season. The TrEO from plants harvested in summer had the highest 50% cytotoxic concentration, 1,476 ng/mL for J774.A1 macrophages, and in spring (90.94 ng/mL) for murine macrophages.

Metal nanoparticles have important applications in medicine and agriculture. The leaves of Tetradenia riparia (Iboza), an important medicinal species in South Africa, are reported to contain various terpenoids and pyrones which can be used in the reduction of silver nitrate (AgNO3) to nano-silver particles. Materials and Methods: Fresh leaves and stems of Iboza were oven-dried, crushed, extracted in water and methanol and filtered followed by incubation with AgNO3. Synthesized nano-silver particles were characterised using ultraviolet visible (UV-Vis) spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy and Fourier transform infrared (FTIR) spectroscopy. Results: The bio-reduction of metal ion to base metal was rapidly conducted in a single step and at room temperature and pressure. UV-Vis spectra showed the characteristic surface plasmon resonance band of the synthesized nano-silver particles at 410 nm for all extracts. SEM analysis revealed predominantly aggregated spherically-shaped nano-silver particles with a size range of 20-50 nm and an average diameter of 26 nm.

The origin of fire-adapted lineages is a long-standing question in ecology. Although phylogeny can provide a significant contribution to the ongoing debate, its use has been precluded by the lack of comprehensive DNA data. Here we focus on the ‘underground trees’ (= geoxyles) of southern Africa, one of the most distinctive growth forms characteristic of fire-prone savannas. 2. We placed geoxyles within the most comprehensive dated phylogeny for the regional flora comprising over 1400 woody species.
