Background: Allium species are generally reputed for their anti-pest properties; however, few studies have focused on optimising the quality and yield of anti-pest bioactive materials from these medicinal plants.Setting: Laboratory and greenhouse experiments were carried out on the Bellville campus of the Cape Peninsula University of Technology, Cape Town.Aims: This research study aimed to evaluate the effect of light intensity on the volatile constituents, antifungal and anti-insect activities of extracts obtained from Allium porrum L. cultivated hydroponically under greenhouse conditions.Methods: Seedlings of A. porrum were hydroponically grown under 40% shading and 0% shading conditions for 12 weeks. The phytochemical constituents of the aerial parts (leaf and bulb) of A. porrum were analysed. The antifungal activity against Fusarium oxysporum and the anti-insect activity on the grapevine mealybug (Planococcus ficus) was evaluated by microdilution and repellency bioassays, respectively.Results: Remarkably, the total polyphenol content was statistically higher (DF = 1, 6; F = 9.17; p 0.05) in plants exposed to 40% shade treatment. The gas chromatography-mass spectrometry (GC-MS) analysis revealed that the volatile compounds varied significantly (DF = 1; χ 2 = 3.435; p 0.05) between the two treatments. However, although a higher number of compounds (73) occurred in plants exposed to 40% shade than in those exposed to 0% shade (58), the shading effect on the number of compounds was not significant (DF = 1; χ 2 = 69.551; p 0.05). The acetone extracts of A. porrum that were cultivated under lower light irradiance showed a higher fungistatic activity against F. oxysporum in the antifungal bioassay.Conclusion: Broadly, this study revealed that lowering light intensity from 313 μmol m-2 s-1 to 153 μmol m-2 s-1 favoured a higher phenolic content, volatile constituents and higher anti-F. oxysporum activities in leeks.

Background: With exception of the desert biome, all of South Africa’s biomes occur in the Eastern Cape. The province is known to have high numbers of livestock that are mostly found in communal farming areas. Multi-drug resistance of gastrointestinal nematodes against major classes of conventional anthelmintics and the high cost of synthetic drugs calls for an urgent search for different control strategies of nematodes.Aim: A survey was conducted to identify and document plant species used to control gastrointestinal nematodes of livestock in Ciko, Goso and Upper Ngqumeya communities in the Eastern Cape Province.Setting: The study included filed observations and transect walks, as well as a standardized questionnaire given to 48 sheep farmers.Methodology: Forty-eight livestock farmers including men and women of mixed ages were interviewed. The information was obtained through the use of a structured questionnaire, field observations and transect walks. Data generated were analysed using descriptive statistics with frequency of citation (FC) and relative frequency of citation (RFC) as quantitative.Results: A total of 11 plant species from different genera were reportedly available and used to control gastrointestinal nematodes. Aloe ferox (0.67) and Zanthoxylum capense (0.44) had the highest values of RFC followed by Strychnos henningsii (0.23) and Elaphantorhhiza elephantine (0.21) and were widely known by the people of the study areas. The three most frequently used plant parts were leaves, roots and bark accounting for about 36.4%, 27.3% and 27.3%, respectively. The ethnoveterinary medicines were prepared in the form of decoctions and infusions. Oral administration of the concoctions was the only route of administration. The major constraints of sheep production as perceived by the farmers were prevalence of internal (36%) and external parasites (18.1%). All medicinal plants used were native and collected from the wild. The most dominant life forms were trees (45.4%), followed by herbs (36.4%) and shrubs (18.2%). Homestead expansion was ranked as the major threat (26%) to medicinal plants followed by firewood (21%). In-situ (protection through rangers) was the most frequently mentioned (67%) conservation practice used by farmers to protect the loss of medicinal plants followed by ex-situ (33%).Conclusion: In the light of data gathered on the surveyed plants, it appeared the plants play a role in the healthcare of sheep in rural communities. Further studies are required to analyse the plants for their chemical composition and biological properties.

Background: Indigenous knowledge is progressively fading out because of a lack of proper record-keeping, as the knowledge is transmitted verbally. There is, therefore, a dire need for preserving this valuable knowledge by ensuring proper documentation and sharing of traditional knowledge.Aim: This research study sought to explore the indigenous knowledge used by herbal medicine practitioners for treating various human ailments in Jos Metropolis of Plateau State, Nigeria.Setting: The study was conducted using a structured questionnaire administered to 100 registered traditional healers in Jos North LGA of Plateau State.Methods: Selected medicinal plants were collected, pressed and transported to the Forestry Research Institute of Nigeria (FRIN), Ibadan for identification, authentication and deposition of voucher specimens for voucher number at FRIN herbarium, Ibadan. Descriptive statistics were used to analyse the ethnomedicinal data.Results: Thirty-nine plant species, distributed in 33 families and 39 genera, were cited by the respondents. The Fabaceae was the most represented family, followed by the Euphorbiaceae and Myrtaceae. Leaves were the most used plant part (29%), whilstthe most cited plant habit forms include trees (48%) and herbs (31%). The herbal remedies were mostly administered orally (53%) and topically (26%), whilst the most common method of preparation was decoction (42%). The highest consensus factor (1.00) was detected for chickenpox or measles or leprosy, haemorrhoids and sickle cell ailments.Conclusion: There is an existence of a wide gap in traditional healing knowledge between the elderly and the younger generations in the study area. The high fidelity level observed in this study implied a general acceptance and preferred usage of such herbal plants for the treatment of particular ailments.
背景:由于缺乏适当的记录，土著知识正逐渐消失，因为知识是口头传播的。因此，迫切需要通过确保传统知识的适当记录和共享来保护这一宝贵的知识。目的:本研究旨在探索草药从业者在尼日利亚高原州乔斯大都会治疗各种人类疾病时使用的土著知识。环境:本研究采用结构化问卷对高原州Jos North LGA的100名注册传统治疗师进行调查。方法:将精选药用植物采集、压实后运至尼日利亚伊巴丹林业研究所(FRIN)进行鉴定、鉴定，并在尼日利亚伊巴丹林业研究所标本室存放凭单号凭单标本。采用描述性统计方法对民族医学资料进行分析。结果:调查对象共引用植物39种，分属33科39属。豆科是最具代表性的科，其次是大戟科和桃金娘科。树叶是最常用的植物部位(29%)，而被引用最多的植物习性形式包括树木(48%)和草药(31%)。草药主要是口服(53%)和局部(26%)，而最常见的制备方法是煎煮(42%)。在水痘、麻疹、麻风病、痔疮和镰状细胞病中发现了最高的共识因子(1.00)。结论:研究区老年人与年轻一代在传统治疗知识方面存在较大差距。在这项研究中观察到的高保真度水平意味着这种草药植物被普遍接受和首选用于治疗特定疾病。

Background: Salvia dolomitica Codd. and Salvia namaensis Schinz. are indigenous to southern Africa and are used as medicinal plants in folk medicine.Aim: This study aimed to assess the effects of different levels of water deficit treatments on the growth, concentration of secondary metabolites, and anti-Fusarium oxysporum activity of S. dolomitica and S. namaensis.Setting: Experiments were carried out on the Bellville campus of the Cape Peninsula University of Technology, Cape Town.Methods: Four weeks old seedlings of the two species were subjected to 3-, 6-, 9- and 12-day water deficit regimes. Secondary metabolites such as polyphenols, alkaloids, and flavanols were assessed using spectroscopic methods. The anti-fungal activities of crude extracts obtained from plants were evaluated in a micro-dilution bioassay.Results: In all treatments, the plant height, crown width, number of stems and leaves, and fresh and dry weights reduced with increased water deficits. Acetone extracts from all treatments showed anti-fungal activity. However, extracts from the treatment with moderate water deficit (6-day watering interval) recorded significantly (P 0.01) better inhibition of F. oxysporum at the 18 h post incubation than the commercial fungicide, Mancozeb.Conclusion: This research has revealed that mild to moderate water deficit level favours the accumulation of alkaloids in S. dolomitica. Meanwhile, mild to severe water deficit significantly lowered flavanol content in S. namaensis. There was a correlation between the increase in total alkaloid contents and the enhanced anti-fungal activity of extracts of S. dolomitica. The present findings pave the way for optimised cultivation of medicinal plants and development of bioactive natural products.

Background: As a result of high percentage of women infected with urinary tract infection (UTI) annually, many rural dwellers use Adansonia digitata fruit pulp as herbal cure. Adansonia digitata L. (Malvaceae) is one of the great trees idolised in Africa because of its therapeutic properties.Aim: This study aimed at identifying chemical compounds in the ethylacetate fraction of the baobab fruit pulp and indicated their biological activities to justify its use for the folkloric treatment of UTI.Methods: The crude extract from Baobab fruit pulp was partitioned and ethylacetate extract was used for assay. Gas chromatography-mass spectrometry (GC–MS) analysis was performed to identify the bioactive compounds in the ethylacetate fraction, antioxidant activity was evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays whilst the total phenolic and flavonoid contents were determined by already adopted protocols. The antibacterial properties were tested against some urinary tract pathogens using macro broth dilution method.Results: A total of 36 bioactive compounds were identified by GC–MS analysis, most of them have been reported as antibacterial, antioxidant, antidiabetic, antiasthma, antifungal, anti-inflammatory and anti-cancer agents. The extract exhibited highest activity against Pseudomonas aeruginosa American Type Culture Collection (ATCC) 19582 (1.22 mg/mL) whilst Escherichia coli ATCC 8739 (˃ 8.6 mg/mL) displayed high level of resistance amongst the five bacterial isolates used in this study.Conclusion: These findings indicated that the extract contained bioactive compounds of therapeutic importance with significant antioxidant and antibacterial potentials and justify the folkloric use of this fruit in the treatment of UTIs by many African dwellers.
