A B S T R A C TFolk medicine is a relevant and effective part of indigenous healthcare systems which are, in practice, totally dependent on traditional healers. An outstanding coincidence between indigenous medicinal plant uses and scientifically proved pharmacological properties of several phytochemicals has been observed along the years.This work focused on the leaves of a medicinal plant traditionally used for therapeutic benefits (Ango-lan Cymbopogon citratus), in order to evaluate their nutritional value. The bioactive phytochemical com-position and antioxidant activity of leaf extracts prepared with different solvents (water, methanol and ethanol) were also evaluated.The plant leaves contained rv60% of carbohydrates, protein (rv20%), fat (rv5%), ash (rv4%) and moisture (rv9%). The phytochemicals screening revealed the presence of tannins, flavonoids, and terpenoids in all extracts. Methanolic extracts also contained alkaloids and steroids. Several methods were used to eval-uate total antioxidant capacity of the different extracts (DPPH . , NO . , and H2O2 scavenging assays, reducing power, and FRAP). Ethanolic extracts presented a significantly higher antioxidant activity (p < 0.05) except for FRAP, in which the best results were achieved by the aqueous extracts. Methanolic extracts showed the lowest radical scavenging activities for both DPPH . and NO . radicals.

“…Namibia is home to about 8159 plant species with therapeutic potential (Hedimbi and Chinsembu, 2012;Ilonga, 2012;Cunningham, 1993;Grote, 2003;Cheikhyoussef et al, 2011;Thomas, 2015). Over 80% of the world's population, mostly in low and middle income countries (LMIC) rely on traditional medicine for primary health care of common ailments (Fabricant and Farnsworth, 2001;Ganatra et al, 2012;Thirumurugan, 2010;WHO, Traditional Medicines, 2012).…”

“…The rising burden of antimicrobial resistance is a wake-up call for further research and development of cost-effective medicines, particularly from the indigenous ethnomedicines of Namibia. In Namibia, concoctions of Colophospermum mopane and Acrotome inflata are widely used traditionally in the management of infectious diseases (Musvoto et al, 2007;Cheikhyoussef et al, 2011;Bainbridge H, 2012). The traditional uses include cure and/or prevention of wound infections and treatment of syphilis, diarrhea, coughs, inflammatory diseases and fevers (Cheikhyoussef et al, 2011).…”

“…C. mopane and A. inflata belong to the Fabaceae and Lamiaceae families, respectively. Secondary metabolites of these families including tannins, alkaloids, and flavonoids have exhibit antimicrobial activity (Cheikhyoussef et al, 2011;Mahesh and Satish, 2008;Lewis and Ausubel, 2006). Thus, extracts of these ethno-medicines from C. mopane and A. inflata may be a potential source of phytochemicals with antimicrobial activity conceivably with better safety profile and/or novel mechanisms against resistant bacteria (Thirumurugan, 2010;Parekh and Chanda, 2007;Tiwari et al, 2011;Cowan, 1999) Phytochemicals such as alkaloids, tannins, saponins and flavonoids have been reported to have antimicrobial activity (Heneman and Zidenberg-Cherr, 2008;Suliman, 2010).…”

Plants with diverse therapeutic properties are indigenous to Namibia. Concoctions of Colophospermum mopane and Acrotome inflata are widely used traditionally in the management of respiratory, gastrointestinal and wound infections. Limited studies have validated these traditional uses particularly against resistant bacteria strains such as Pseudomonas spp. This study aimed to determine the antimicrobial activity and phytochemistry of extracts of C. mopane and A. inflata, medicinal plants indigenous to Namibia. Phytochemical analysis and antimicrobial testing were done on leaves and barks of C. mopane and A. inflata whole plant. Voucher specimens were collected from Omugulugoonime village, Oshikoto region and validated at the National Botanical Research institute, Windhoek. Crude extraction of dried plants was done by maceration with ethanolic and aqueous solvents. Phytochemical screening was done using methods described by Harborne (1998) and/or Tiwari et al (2011). The antimicrobial activity against wild types of Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtillis and Candida albicans was done using the disc-agar-diffusion method. The mean diameters of the zones of inhibition (mm) for each extract were determined against each test organism. The antimicrobial activity (zones of inhibition) of ethanolic extracts (5 mg/ml) of C. mopane bark (10±0.6 mm) and leaves (10±1.2 mm) and A. inflata (8.7±0.6 mm) against P. aeruginosa is comparable to that of penicillin G (14±1.4 mm). Aqueous extracts leaves and bark of C. mopane showed activity against P. aeruginosa and S. aureus. The activity of the ethanolic extracts against B subtillis was: C. mopane leaves (7.3±0.6 mm), C. mopane bark (8.7±0.6 mm) and A. inflata (11.3±3.21 mm) and Penicillin G (26±1.4 mm). Both ethanolic and aqueous extracts did not have activity on C. albicans. Aqeous extracts of A. inflata had no activity on Pseudomonas and B. subtillis. Organic extracts of Colophospermum mopane and A. inflata exhibit antimicrobial potential against Pseudomonas and Bacillus species. The alkaloids, flavonoids and tannins should be further purified and characterized for antipseudomonal activity.

Current vegetation structure and composition of woody species in community‐derived categories of land degradation in a semiarid rangeland in Kunene region, Namibia

et al. 2020

Land degradation has put the world's rangelands under intense pressure and reduced their capacity to provide vital services to those who solely depend on them for survival. With the current pressures on rangelands, worldwide, there is an urgent need to survey the present condition of rangelands. Such detailed surveys can identify where improvement programmes can be emphasised; whether it be reseeding, stock control, sociological restraints or other actions. To combat rangeland degradation, management systems are more effective when they account for community perceptions and practices. This study aims to assess the current status of woody plants in different categories of degradation as perceived by herders in Kunene, Namibia. Furthermore, we wished to compare the perception of degradation by herders with the measured ecological condition. With the help of herders, sites representing different categories of degradation (low, moderate, high and protected) were identified and 10 plots of 400m 2 each were established in each category. Species diversity, density, basal area and regeneration of woody plants increased sequentially along the degradation gradient (high to low). Vegetation attributes such as species diversity, seedling density and standing basal area increased with increasing distances from the villages. Although the herders' perception of degradation, for high and moderate degradation, matches the ecological results, the low degradation sites show signs of bush encroachment, a type of degradation that the herders did not perceive as degradation. Colophospermum mopane, a known encroacher species across Namibia, was the dominant species in the moderate and low degradation sites. Pechuel-loeschea leubnitziae, which is also known to be an indicator of degradation, was the dominant species in the high degradation sites. The findings highlight the present and future threats the study area is facing and form the basis for current restoration research.
