This ethnobotanical study on plants used for the treatment of sexually transmitted infections was undertaken to document the knowledge by lay people in a rural community in northern Maputaland, South Africa. The focus was on the medicinal plants which are growing in and around the immediate vicinity of the homesteads.
The increasing prevalence and distribution of malaria has been attributed to a number of factors, one of them being the emergence and spread of drug resistant parasites. Efforts are now being directed towards the discovery and development of new chemically diverse antimalarial agents.
The ethanolic extract of a Malagasy species Euphorbia stenoclada (ES) (Euphorbiaceae), traditionally used as a herbal remedy against asthma and acute bronchitis, was tested to evaluate possible anti-proliferative activity on human airway smooth muscle cells (HASMC). The ES ethanolic extract totally abolished the interleukin-1 (IL-1) induced proliferation of HASMC (IC50 = 0.73 ± 0.08g/mL).
Ethnopharmacological relevance: Through this study, relevantinformation was gathered on the knowledge about medicinal remedies in some rural communities of Muda (central Mozambique). The use of 198 different medicinal plants has been recorded and a significant number of medicinal species and uses new for Africa and particularly for Mozambique has been detected.
Ethnopharmacological relevance: Traditional remedies from plants have been use to treat male reproductive related disorders for ages in South Africa. Aim: This study reviewed the current status of medicinal plants used in male reproductive healthcare as well as their effectiveness as a mode of treatment.
This paper reviews the antimicrobial research undertaken on South African medicinal plants during the period 1997–2008. Antimicrobial methods (disc diffusion, minimum inhibitory concentration (MIC), bioautography) are briefly discussed and an analysis of the publications reviewed indicates that the majority of papers use MIC assays for antimicrobial determination.
Results from the in vitro antiamoebic activity of some Congolese plant extracts used as antidiarrhoeic in traditional medicine indicated that of 45 plant extracts tested, 35 (77.78%) exhibited an antiamoebic activity and 10 (22.22%) were inactive.
The flavonoids contained in Euphorbia neriifolia leaves were extracted, identified and characterized. Direct and sequential soxhlet extraction and its concentrated fractions were subjected to thin layer chromatography and high performance thin layer chromatography. The results showed that maximum yield of the flavonoid (6.53 g) was obtained from ethanolic extract.
Sixty-seven crude ethanol extracts from 50 plants (31 families), which are used in North Cote-d’Ivoire as traditional remedies for bacte- ˆ rial diseases, were screened for in vitro activity against Gram negative (Escherichia coli and Pseudomonas aeruginosa) and Gram positive (Staphyloccocus aureus, Enterococcus faecalis, Streptococcus pyogenes and Bacillus subtilis) bacteria.
The chemical constituents of some species of Euphorbia, which grow mostly in semi-desert areas in Iran and on the Alborz Mountains in the north of Tehran, have been found to include chemotaxonomically important myrsinane diterpenoids and cycloartane triterpenoids.
