Abstract:
Cutaneous leishmaniasis is a common anthropozoonosis and a major public health problem in Algeria. Therefore, we conducted an ethnopharmacological survey in the locality of Ain Sekhouna (located in the highlands of western Algeria), one of the foci of cutaneous leishmaniasis. We aimed to identify the medicinal plants and natural remedies used by the local population to treatment cutaneous leishmaniasis. We identified three plant species, belonging to three distinct families, used as natural remedies against the disease, namely, Haloxylon scoparium Pomel (Chenopodiaceae, 73%), Artemisia herba-alba Asso. (Asteraceae, 18%), and Camellia sinensis L. (Theaceae, 9%). Additionally, 35% of the plant-based medicines mostly comprised the powdered form of the aerial parts of the plant. According to the respondents, the powder is combined with butter, cade oil, or honey and is applied exogenously on the skin. Overall, these medicinal plants can be used as a source of natural medicines, in combination with commonly used dermatological excipients, to treat cutaneous leishmaniasis.

Abstract:
Extracts of Sutherlandia frutescens (cancer bush) exhibit considerable qualitative and quantitative chemical variability depending on their natural wild origins. The purpose of this study was thus to determine bioactivity of extracts from different regions using in vitro antioxidant and anti-cancer assays. Extracts of the species are complex and are predominantly composed of a species-specific set of triterpene saponins (cycloartanol glycosides), the sutherlandiosides, and flavonoids (quercetin and kaempferol glycosides), the sutherlandins. For the Folin-Ciocalteu phenolics test values of 93.311 to 125.330 mg GAE/g DE were obtained. The flavonoids ranged from 54.831 to 66.073 mg CE/g DE using the aluminum chloride assay. Extracts from different sites were also assayed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging method and ferric reducing anti-oxidant power (FRAP) methods. This was followed by an in vitro Cell Titer-Glo viability assay of various ecotypes using the DLD-1 colon cancer cell line. All test extracts displayed anti-oxidant activity through the DPPH• radical scavenging mechanism, with IC50 values ranging from 3.171 to 7.707 µg·mL−1. However, the degree of anti-oxidant effects differed on a chemotypic basis with coastal plants from Gansbaai and Pearly Beach (Western Cape) exhibiting superior activity whereas the Victoria West inland group from the Northern Cape, consistently showed the weakest anti-oxidant activity for both the DPPH• and FRAP methods. All extracts showed cytotoxicity on DLD-1 colon cancer cells at the test concentration of 200 µg·mL−1 but Sutherlandia plants from Colesburg (Northern Cape) exhibited the highest anti-cancer activity. These findings confirm that S. frutescens specimens display variability in their bioactive capacities based on their natural location, illustrating the importance of choosing relevant ecotypes for medicinal purposes.

Abstract:
Agathosma betulina, commonly known as buchu, has been used for centuries by the indigenous people of South Africa for medicinal purposes. Currently, the essential oils from buchu are used in medicine, food flavorings, and aromatic oils. Increased exploitation of natural growing buchu in the Fynbos biome and a worldwide shortage of buchu oil encouraged commercial cultivation in South Africa. The root-knot nematode (Meloidogyne spp.) is one of the most common plant-parasitic nematodes found on commercial crops grown in the Western Cape. It has also been isolated from the soil and roots of plants in the natural Fynbos vegetation (2). In June 2003, a nursery propagating buchu plants experienced problems with poor growth. Examination of the buchu roots under a stereo microscope showed extensive galling with large numbers of female root-knot nematodes with eggsacs. Nematode extractions of the soil were also done. Only second-stage juveniles of Meloidogyne spp. (311 per 250 ml of soil) were recovered. A polymerase chain reaction (PCR)-based diagnostic method (1) was used for the identification of the root-knot nematode species. Ten intact females were dissected from the roots and individually placed directly in 5 μl drops of 1× PCR reaction buffer (16 mM [NH4]2SO4, 67 mM tris-HCL, pH 8.8, 0.1% vol/vol Tween 20) ontaining 60 μg/ml of proteinase K. The tube was kept at -80°C for a minimum of 10 min. The tube was incubated at 60°C for 15 min and 5 min at 95°C. The PCR amplifications were then prepared directly in the same tube. Amplified DNA fragments were digested with HinfI and DraI. The digested DNA was loaded on a 2% agarose gel, separated by electrophoresis, and detected by ethidium bromide staining. The digested amplified DNA fragments correspond to those of Meloidogyne javanica. Morphological characteristics were used to verify the PCR-based identification of the nematode. To our knowledge, this is the first report of M. javanica causing extensive galling on the roots of Agathosma betulina. Visual damage to the roots indicates the root-knot nematode to be an important threat to the commercial cultivation of buchu. References: (1) R. Knoetze.

Abstract:
AbstractThe potential distribution of the South African weevil, Perapion antiquum (Gyllenhal), a biological control agent for the weeds Emex spp., was deter mined by the computer program CLIMEX, using its native distribution, phenology and abundance together with development parameters. The predicted distribution included parts of Hawaii where the weevil successfully controlled Emex australis and E. spinosa. In Australia, sites of past unsuccessful releases have climates that this analysis indicates are unsuitable for the insect. The most favourable regions for establishment of the weevil are near the coast in the southern half of Australia, but most of these do not overlap with regions where Emex spp. are a problem. In western Cape Province, South Africa, E. australis plants are abundant and the weevil attacks the plant after seeds have formed. In Hawaii, a fortuitous combination of climatic conditions favours the weevil during the period after seed germination, and this may be the key to its control of the weed. Sites with climatic conditions similar to successful control sites in Hawaii are not found in Australia. It was concluded that P. antiquum will be of limited use as a biological control agent in Australia even in areas suitable for its establishment.

Abstract:
In Mediterranean-Climate Ecosystems (MCEs), Holocene coastal dunes comprise small, fragmented and dynamic features which have nutritionally imbalanced and excessively drained, droughty, sandy soils. These characteristics, along with summer drought and salt-laden winds, pose many challenges for plant colonization and persistence. Consequently, MCE dune floras are likely to be distinctive with a high proportion of habitat specialists and strong convergence in growth form mixes. Very little research has compared the species traits of dune floras within and across MCEs. This paper contributes to filling that gap. Here, we analyze the taxonomic, biological and geographical traits for all 402 species in a flora from a dune landscape (Cape St Francis) in the southeastern Cape Floristic Region (CFR) and compare patterns with the trait profiles of other dune floras at a regional (CFR) and global (MCE) scale. Within the CFR, the southeastern (all-year-rainfall) flora at Cape St Francis had a similar trait profile to western (winter-rainfall) dune floras, except for having a lower representation of species belonging to CFR-endemic clades, and higher number of species associated with tropical lineages. The St Francis flora, in common with other CFR and MCE floras, was dominated by members of the Asteraceae, Fabaceae and Poaceae. Some 40% of the St Francis flora was endemic to the CFR, typical of the high rate of MCE-level endemism elsewhere in the CFR, and in other MCEs. About 30% of the flora was confined to calcareous sand, a value typical for many other MCE sites. The St Francis flora, as well as other CFR dune floras, differs from those of other MCEs by having many species associated with shrubby lineages, and by the relatively high incidence of species associated with tropical lineages. The growth form profile of the St Francis and other CFR floras shows strongest similarity with that of Australian MCE dunes in that in both regions, evergreen hemicryptophytes and shrubs share dominance, and annuals are floristically and ecologically subordinate. The least similar of MCEs to the St Francis trait profile is the Mediterranean Basin where annuals are the most frequent growth form while shrubs are subordinate. California and Chile dune floras appear to occupy an intermediate position, in terms of growth form mix, between the Cape and Australia on the one hand, where dune floras have retained features typical of nutrient-poor soils, and the Mediterranean Basin, where dwarf, deciduous shrubs and annuals dominate the life form spectrum. All MCE dunes are threatened by alien plants, infrastructure development, tourism demands and rising sea levels. The high incidence of species of conservation concern in CFR dune floras underestimates the exponentially increasing threats to their habitats, which are already historically at a much-reduced extent. All remaining coastal dune habitat in the CFR, and probably in other MCEs, should be conserved in their entirety.

Abstract:
This study refers to the use of medicinal plants by populations in the Western Amazon and provides information that can be used in phytochemical studies. It draws upon the traditional knowledge regarding the use of medicinal plants in five regions of the state of Rondônia, in the Brazilian Amazon, focusing on native species. The field research was carried out in five municipalities of the state of Rondônia: Ariquemes, Buritis, Candeias do Jamari, Cujubim and Itapoa do Oeste, characterized by primary economic sectors: agriculture, cattle farming, plant extraction and mineral exploration. Structured interviews were applied to 227 persons chosen because of their prestige in the communities in relation to the knowledge and use of medicinal plants, identifying the therapeutic purpose, parts of the plant used and methods of preparation. The species were taxonomically identified. The ethnobotanic knowledge (inferred by the number of uses of medicinal plants per person) was correlated with the Brazilian region of origin, age, and gender of the interviewees. According to the collected data, 34 botanical families and 53 native species were identified. Of the 53 species, only 7 occur exclusively in the Amazon Forest: Theobroma grandiflorum (Willd. ex Spreng.) K. Schum., Psidium densicomum Mart. ex DC, Piper cavalcantei Yunck., Pilocarpus microphyllus Stapf ex Wardlew., Euterpe oleracea Mart., Croton cajucara Benth., Baccharis altimontana G. Heiden. The most common disorders treated with the plants were kidney problems, influenza, generalized infections and inflammations, malaria and high blood pressure. Leaves were the most used parts in preparations. Barks, fruits, roots, flowers, stems, seeds, oils, buds, tubercles, and rhizomes were also mentioned. Thirteen forms of preparations were recorded, and infusion and decoction were the most used. Syrups, juices, flour, sap, oil and parts of the plant blended with milk, honey and coffee or flamed, macerated and in the form of poultice, were also found. Persons from the Southeast region had more information compared with persons from the other regions; persons in the age groups between 50-59, 60-69 and 70-79 had more information in comparison with the other age groups; and the female interviewees mentioned significantly more uses of medicinal plants than the male ones. The relatively small number of native Amazon species identified can be the result of the loss of knowledge about medicinal plants in the Amazon because of internal migration, extinction of local indigenous groups, increasing urbanization and consequent globalization of the lifestyles.

Abstract:
Abstract Bulgaria is one of the European countries with the greatest biodiversity, including biodiversity of medicinal plants. The object of this study is Chepan Mountain. It is located in Western Bulgaria and it is part of Balkan Mountain. On the territory of the Chepan Mountain (only 80 km2) we found 344 species of medicinal plants from 237 genera and 83 families. The floristic analysis indicates, that the most of the families and the genera are represented by a small number of inferior taxa. The hemicryptophytes dominate among the life forms with 49.71%. The biological types are represented mainly by perennial herbaceous plants (60.47%). There are 7 types of floristic elements divided in 27 groups. The largest percentage of species are of the European type (58.43%). Among the medicinal plants, there are two Balkan endemic species and 18 relic species. We described 23 species with protection statute. The anthropophytes among the medicinal plants are 220 species (63.95%).

ENGLISH ABSTRACT: Buchu (Agathosma betulina and A. crenulata) are grown commercially as an aromatic crop and are endemic to the Western Cape of South Africa. Poor rooting of cuttings have limited the development of superior clones. Under standard mist bed conditions terminal, sub-terminal or basal stem cuttings were taken from March to August. When not treated with an auxin, rooting percentages of between 20 and 25 were obtained. Rooting percentages increased to between 40 and 45 after treatment with 500-1000 ppm indolebutyric acid (lBA). Substituting lBA with naphthaleneacetic acid (NAA) did not improve rooting. There was a tendency for cuttings with fewer than four leaf pairs to give lower rooting percentages. Plants of Agathosma betulina x A. crenulata, grown in Paarl, and A. betulina, grown in Piketberg, were used as source plants for making cuttings. Paarl plants were shaded with 80 percent shade and Piketberg plants with 60 or 80 percent shade respectively from February to October 2002. Plants in full sun served as a control. Plants were pruned back initially in February and then two months before samples were taken in March, June, August and October at both locations. New shoots were used as cuttings. Terminal cuttings for rooting and for carbohydrate analyses were collected on four different dates (March, June, August and October). Cuttings were treated with 500 ppm indolebuteric acid (lBA) and placed in misting beds with bottom heating (18-25°C) for a period of three months. Shading reduced rooting of cuttings from the Paarl plants. However, it did not significantly increase rooting of cuttings taken from Piketberg plants. Rooting percentage was the highest in August (43%) for cuttings from sun grown plants in Paarl. No consistent relationship between, respectively, dry mass or carbohydrate content of cuttings and rooting could be established. Terminal current years' growth, taken from Agathosma crenulata x A. betulina (hybrid) softwood cuttings, collected in January 2002, were extracted with methanol and fractioned by thin layer chromatography (Silica gel) in isopropanol: acetic acid: water (4: 1:1 v/v). The chromatographs were divided in ten fractions and were bio-assayed for a rooting co-factor with the mung bean rooting test. Extracts from buchu cuttings showed significant activity at the Rf values of co-factor 3. Co-factors 1,2 and 4 do not seem to be present in significant quantities. However, co-factors with Rf values different from previous reported values were present in significant quantities. No inhibition was found in buchu. In fact, all Rf values stimulated rooting.
AFRIKAANSE OPSOMMING: Boegoe (Agathosma betulina x A. crenulata) word kommersieël verbon as 'n aromatiese gewas en is endemies tot die Wes-Kaap. Die ontwikelling van superieure klonale materiaal word beperk deur swakbeworteling. Terminale, sub-terminale en basale steggies is gesnyonder standaard misbed toestande van Maart tot Augustus. Beworteling was tussen 20 en 25 persent as geen ouksien gebruik word nie. As indolebottersuur (IBS) gebruik word tussen 500-1000 dpm, verhoog die bewortelingspersentasie tot tussen 40 en 45 persent. Die gebruik van naftaleen asynsuur (NAS) in plaas van IBS het nie beworteling verbeter nie. Daar was a tendens dat steggies wat minder as vier blaarpare gehad het 'n verlaging in bewortelingspersentasies gehad het. Plante van Paarl, A. betulina x A. crenulata, en Piketberg, A. betulina, is gebruik as plantmateriaal vir steggies. Plante in die Paarl was onder 80 persent skadu geplaas en plante in Piketberg onder 60 en 80 persent skadu van Februarie tot Oktober 2002. Plante in vol son was as 'n kontrole gebruik. Plante was eers in Februarie teruggesny en dan weer twee mande voor monsters geneem is. Die monsters is in Maart, Junie, Augustus en Oktober geneem in beide liggings. Terminale steggies is vier keer ingesamel (Maart, Junie, Augustus en Oktober) vir beworteling en koolhidraat analises. Die steggies is met 500 dpm IBS behandel. Daarna is die steggies vir drie maande in die misbed geplaas met bodem-verhitting (18- 25°C). Dit is gevind dat die gebruik van skadu die beworteling in Paarl verminder het alhoewel die beworteling in Piketberg nie beduidend beinvloed is nie. Die hoogste bewortelingspresentasies is waargeneem in Augustus (43%) in Paarl van plante wat in vol son was. Geen verband tussen onderskeidelik die droe massa of koolhidraat inhoud en beworteling kon gevind word nie. Terminale steggies van dieselfte jaar se groei van Agathosma betulina x A. crenulata (hibried) is in Januarie 2002 ingesamel. Die materiaal is geëkstraheer en gefraksioneer deur dunlaag kromatografie in isopropanol: asynsuur: water (4: 1:1 v/v). Die kromograaf is in 10 fraksies verdeel. Die fraksies was bioassaieer VIr beworteling ko-faktore met die mungboontjie bewortelingstoets. Die ekstrakte van boegoe het beduidende aktiwiteit by die Rf waardes van ko-faktor 3 getoon. Ko-faktore 1, 2 en 4 is nie in groot genoeg hoeveelhede waargeneem nie. Ko-faktore, wat nie voorheen gevind is nie, is waargeneem in beduidende hoeveelhede. Geen inhibitors is in boegoe gevind nie en al die getoetste ko-faktore het beworteling gestimuleer.

Abstract:
Magister Scientiae (Biodiversity and Conservation Biology)
South Africa is recognised worldwide for its rich diversity of plants, many of which have been used in ethno-medicine. However, the use of wetland plant species in ethno-medicine required further investigations. This research is aimed at investigating three wetland medicinal, plant species, Centella asiatica, Cyperus longus and Typha capensis based on their geographical, seasonal, mineral nutrient (Fe, Mn, Ca, Mg, K and Na) and secondary metabolite characteristics. Samples of each species were collected from Grabouw, Kelderhoff, Kenilworth, Pringle Bay, University of the Western Cape (UWC) and Worcester within the Western Cape Province of South Africa. Specimen and soil collections were carried out during autumn, spring, summer and winter of 2014. Both plant and soil samples were acid digested and mineral nutrient concentrations in the samples were analysed using an atomic absorption spectrometer (AAS). Secondary metabolites were determined using analytical TLC on normal phase Merck-Silva gel coated aluminium plates as well as by using HPLC separation from crude extracts of C. asiatica, C. longus and T. capensis using LC-MS hardware from Agilent. The elemental analysis of soil samples showed that Ca, K, Mg, Mn and Zn concentrations were predominantly low. Soil mineral concentrations increased progressively from inland (Worcester) towards the coastland in the south (Pringle Bay). Calcium and sodium concentrations, in particular, were higher in soil samples obtained from Grabouw (inland south) and decreased northward towards Worcester. Comparatively, plant mineral concentrations were generally higher than soil concentrations. The high concentration of some of these essential elements, in selected plants is an indication that these plant species could be a good source of essential elements. High concentrations of phytochemicals were found in Centella asiatica during winter, while Cyperus longus and Typha capensis exhibited high concentrations during autumn indicating variation in respect of season. Consequently, harvesting of the studied plants should be done at the season with a relatively high phytochemical concentration. Studies are needed to investigate the extent of pesticide or herbicide contamination in wetland plants to protect the health of users. The LC-MS analyses of the three study species showed that seasonal variation affects metabolite constituents and moreover that these metabolite constituents differ from one locality to another. The seasonal variation of the elements in the studied medicinal plants justified the importance of harvesting seasons in the optimal utilization of the studied plants for medicinal purpose. s, for C. asiatica, anti-bacterial treatments for C. longus and fertility enhancement and birth control for T. capensis.

Abstract:
This dissertation is based upon research of an emergent ethnomedicine in a botanically rich area, the Western Cape of South Africa. It examines the interface between ethnobotany and medical anthropology by investigating the biological and social factors related to the knowledge, use and trade of medicinal plants by Cape bush doctors. Incredible syncretism was observed in the identity formation of this homogenous urban group of healers who combined elements of a globally recognized eco-religion and sociopolitical movement Rastafari with several South African cultures through knowledge of medicinal plants. By rejecting colonial principals, including capitalistic biomedical systems, bush doctors have crafted a niche acquiring knowledge and herbal remedies for the treatment of common ailments. Transmission amongst Rastas and trail-and-error experimentation with herbs emphasize that plant knowledge is situational and arises through relationships. From an estimated 200 bush doctors in the Cape, 62 almost exclusively middle-aged coloured males were interviewed. They declared their mission was 'to heal all people' through a reintroduction of KhoiSan healing traditions, an indigenous ancestry largely rejected by coloureds during apartheid. An ethnobotany of bush doctors revealed that of 192 species, 181 were medicinal and included various herbs important to most South African cultural groups. This largely herbaceous pharmacopeia is narrow compared to the region's high biodiversity and thirty-three species were identified as conservation priorities. The presence of bush doctors at transportation hubs as herbal hawkers creates a diversified economy through cultivation of relationships with primarily disadvantaged coloured and black consumers. The consumption, trade and sale of local plants by bush doctors represent efforts to embody the landscape; it reasserts coloured links to indigeneity, renews respect for their heritage and affords rights to resources. By evoking tradition within their tolerant philosophy, leaders of this emergent ethnomedicine develop a racially equitable and ecologically sustainable platform for health care evidenced by medicinal plant gardens in townships and transmission of diverse ethnomedical knowledge. Bush doctors are legitimized through the performance of transmission. This phytomedicinal knowledge reifies an ideology, repositioning coloureds in a moderate stance between colonial biomedicine and traditional African ethnomedicines, but also creates a unified South African medicine.

In our search for new anti-tuberculosis lead molecules, five medicinal plant species, Olea capensis (L.l, Tulbaghia alliacea (L.), Inula graveolens (L.), Leyssera gnaphaloides (L.), and Buddleja saligna (L.) were collected in Cape Town and surrounding area and investigated for antimycobacterial activity following report of their therapeutic use in traditional medicine to treat infectious diseases such as tuberculosis. A bioassay guided fractionation of the acetone/water (4:1) crude extracts of O. capensis (leaves) and T. alliacea (rhizomes) showed no activity against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 252923, and Mycobacterium aurum A+. In contrast, the orgamc fractions (hexane, dichloromethane) of the acetone/water (4: 1) crude extracts of 1. graveolens, L. gnaphaloides, and B. saligna exhibited significant activity against M. tuberculosis H37Rv, M. avium 25291, M. microti ATCC 19422, and M. scrofulaceum ATCC 19987. The isolation and structure determination of the bioactive led to the identification of pentacyclic triterpenoids, ursolic acid (UA) and oleanolic acid as major antitubercular constituents of B. saligna, L. gnaphaloides, and 1. graveolens. The in vitro cytotoxicity assays of the isolated bioactive constituents showed no cytotoxicity against Chinese Hamster Ovarian (CHO) cells line. Subsequently, given the pharmaceutical value of the above finding, a survey on structure activity of pentacyclic triterpenoids was conducted. It was was found, for instance that selective substitutions at C-3 and/or C-28 and the double bond at UA, OA and betulinic and (1) BA) were made in order to improve anti-tumour and anti-HIV activity. However, thought a great number of modified bioactive pentacyclic triterpenoids is reported, none was tested against Mtb. Therefore, this study also explored a new synthetic route (scheme 1) toward a generation of (5), which may allow improving antitubercular, anti-HIV or anti-tumour activity, and/or specificity.

ENGLISH ABSTRACT: This study analyses the extent to which the current intellectual property system is suited to the protection of traditional knowledge in the Western Cape. Employing a multidisciplinary approach that incorporates economic and legal theory as well as legal philosophy, this study argues that although advances in the fields of biotechnology has brought with it the need for greater intellectual property rights protection, the protection of traditional knowledge has largely been ignored. Traditional ethnobotanical knowledge holds immense economic value for both commercial entities seeking to develop products based on traditional knowledge as well as for the communities that possess such knowledge. Protecting traditional knowledge is necessary to ensure that the communities contributing their knowledge are recognized and compensated for such contributions. In order for a system to provide adequate protection for traditional knowledge it has to be consistent with and suited to the needs of traditional knowledge holders. This study therefore evaluates the prevailing system of knowledge protection as embodied in the intellectual property rights regime as a means of protecting traditional knowledge. The analysis reveals that the dominant justification for the existence ofIPRs is based on utilitarian considerations that promote IPRs as a necessary incentive encouraging innovative activity. This utilitarian justification also provides the basis for an economic justification for the existence of IPRs that suggests that the conferring of exclusive rights (in the form of IPRs) to innovators ensure that such innovators are able to recover their research costs and realize profits from their inventions. The IPR system as it exists is underpinned by these considerations and embedded in principles of individualism and private property. The WTO reinforces and promotes this approach to intellectual property in the TRIPs agreement by recognizing intellectual property as a 'trade related' issue. The inclusion of IPRs as a 'trade related' issue in the multilateral framework of the WTO reflects the interests of multinational corporations and developed nations who rely extensively on these mechanisms to maintain their power and wealth in an increasingly knowledge driven global economy. The exclusion of traditional knowledge within the TRIPs, coupled with the desire to extend patents to cover life forms is also indicative of this bias inherent in the system. South African intellectual property legislation is then applied to the traditional knowledge of an indigenous medicinal plant to test whether IPRs are able to provide adequate protection to traditional knowledge. In this regard it is found that patent protection, which could potentially provide the greatest form of protection for traditional knowledge is. not suited to the needs of traditional knowledge holders. Problems of identifying owners, determining inventors and novelty, time limited rights and costs all limits the potential of patents as a tool for protecting traditional knowledge. Similar constraints limit the potential of other categories of IPRs to provide protection for traditional knowledge. However, it was found that IPRs do provide a certain measure of defensive protection. The study therefore concludes that the IPR system as it exists, both in the international trade environment as well as at the national level, fails to adequately address the threat of appropriation and the concerns of traditional knowledge holders. Amending the IPR system and/or developing sui generis systems of protection are therefore necessary to ensure that the knowledge of communities are protected and such communities are able to benefit from the exploitation oftheir knowledge and resources.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie is om vas te stel in hoe 'n mate die huidige sisteem vir die beskerming van intellektuele eiendom geskik is vir die beskerming van tradisionele kennis in die Wes-Kaap. 'n Multidissiplinêre benadering, wat uit elemente van ekonomiese- en regsteorie sowel as regsfilosofie haal, is gevolg om te wys dat die beskerming van tradisionele kennis grootliks geïgnoreer is, alhoewel nuwe deurbrake in biotegnologie die behoefte skep vir groter bekerming van intellektuele eiendom. Tradisionele etnobotaniese kennis het geweldige ekonomiese waarde vir beide die kommersiële entiteite wat produkte uit sodanige kennis wil produseer sowel as vir tradisionele gemeenskappe aan wie die kennis behoort. Dus, indien sulke gemeenskappe voordeel wil trek uit hierdie kennis, is dit nodig dat hul bydraes erken moet word, en dat hulle daarvoor vergoed moet word. Sulke beskerming sal net doeltreffend wees indien dit aangepas is by die behoeftes van hierdie gemeenskappe. Dus word die huidige sisteem vir die beskerming van tradisionele kennis geevalueer in hierdie studie. Die ondersoek wys dat die sisteem vir die beskerming van intellektuele eiendom berus op die teoretiese basis van nutsmaksimering, waar die hoofdoel te vinde is in die bydrae wat dit kan maak tot ekonomiese welvaart deur middel van innovasie. In hierdie opsig word beskerming van intellektuele eiendom beskou as 'n manier waardeur die innoveerder sy navorsings- en ontwikkelingskostes kan delg en wins kan maak. Hierdie benadering word onderskryf deur die WTO in die TRIPS Ooreenkoms. In hierdie opsig word die belange van veral die ryk lande en die multinasionale maatskappye bevorder, 'n sleutelvoordeel in 'n wêreld waar kennis gepaardgaan met mag in die mark. Hierdie verskynsel word versterk deur die uitsluiting van tradisionele kennis van die TRIPS Ooreenkoms en die behoefte daaraan om patentregte uit te brei. Suid-Afrikaanse wetgewing oor intellektuele eiendom word vervolgens toegepas op die geval van tradisionele kennis oor 'n inheemse medisinale plant om te toets of intellektuele eiendomsreg genoegsame beskerming aan tradisionele kennis bied. Daar is gevind dat patentregte, wat potensieël die grootste mate van beskerming sou kon bied, nie gepas is in die geval van houers van tradisionele kennis nie. Probleme wat voorkom sluit in die identifisering van eienaars, innoveerders en innoverings, die tydsbeperking op regte, asook kosteoorwegings. Ander vorms van beskerming is aan soortgelyke kritiek onderhewig, alhoewel bevind is dat intellektuele eiendomsreg wel 'n mate van defensiewe beskerming bied. Die gevolgtrekking word dus gemaak dat die huidige vorms van beskerming vir intellektuele eiendomsreg, beide internasionaal sowel as in Suid-Afrika, nie die belange van die houers van tradisionele kennis beskerm nie. Dit is dus nodig om die huidige vorms aan te spreek, of om sui generis beskerming te ontwikkel om hiervoor te sorg.
