The extract inhibited the growth of all the bacterial and 15 fungal isolates tested.
Euphorbiaceae, subfamilies Phyllantoideae, Oldfieldioideae, Acalyphoideae, Crotonoideae and Euphorbioideae, tribe Hippomaneae. These compounds showed significant antimicrobial activity against several gram-positive and gram-negative bacteria and fungi. View at Google Scholar M. Determination of Antibiograms of A. The sensitivity patterns, minimum inhibitory concentrations MICsand minimum fungicidal concentrations MFCs exhibited by Alchornea laxiflora crude leaf extract against tested fungal isolates.
Seeds ovoid to almost globose, c. Flowers unisexual, sessile; male flowers with 2—4 —5almost round alchornsa ovate, reflexed, yellowish green or white sepals, petals absent, stamens 8—9, filaments united into a basal plate; female flowers with 5—6, almost laxitlora to ovate, acute, unequal, slightly toothed sepals, petals absent, ovary superior, almost globose, c.
Infectious diseases caused by bacteria, fungi, and viruses are still in increase and they are still the major threat to public health. Citation in web searches. Efforts are still ongoing to search for new alchornes active compounds from natural sources as new antimicrobial agent with a view to discovering new chemical structures which could overcome the multiple resistances developed by the pathogenic microbes toward available antimicrobial agents.
The anti-oxidant activity of the root and leaf extracts have been compared laxiflkra that of the standard anti-oxidant butylated hydroxyanisole.
The crude leaf extract of A. Flora of Tropical East Africa. Volume 9, part 4. Dermatophytes such as Trichophyton tonsuransT. Abstract Alchornea laxiflora leaf extract was tested alchorrnea a range of microorganisms using standard microbiological methods for antimicrobial activities. Deciduous, erect to straggling shrub or small tree up to 7 —10 m tall, monoecious with male and female inflorescences on separate branches; bark smooth, pale grey, flaking; young shoots shortly hairy to almost glabrous.
Medicinal plants of East Africa. These were later examined for the presence or absence of growth. In Laxjflora the ground leaves are taken in water to treat hernia. Other authors, Oloyede et al. The medium was poured into sterile Petri dishes and allowed to set. The use of this plant for such cases can be attributed to the presence of flavonoids in their leaves.
The spores were later standardized before use. Antitoxicity, anticonvulsant, and sedative effects of the leaf extract of A. Medicinal plants have been in existence since creation and these plants synthesize a wide variety of phytochemicals which include alkaloids, tannins, flavonoids, steroids, saponins, and phenols, which are all useful sources of medicine [ 1 ].
Alchornea laxiflora (Benth.) Pax
View at Google Scholar G. The extract exhibited antibacterial and antifungal properties as shown in Tables 1 and 2. One hundred microliters of each of the standardized bacterial and fungal suspension was evenly spread on Mueller-Hinton agar medium for bacteria and malt extract medium for the fungi using a sterile glass spreader.
Preliminary phytochemical screening revealed the presence of alkaloids, cardiac glycosides, saponins and phenolic compounds in the roots, and in lower amounts, in the leaves. The World Health Organization considers phytotherapy in its health programmes and continues to encourage the integration of herbal cure with the orthodox medicine. Alchornea laxiflora Syntype of Alchornea schlechteri Pax The antibiograms of the extract along with those of the antifungal and antibiotic were determined using agar-well diffusion methods by [ 1213 ] with little modification.
Showing 0 of 0 comments. The phytochemical analyses of A. The plates were allowed to stand on the laboratory bench for laxifflora hour to allow for proper diffusion of the extract solution into the medium.
Medpharm Scientific, Stuttgart, Germany. These compounds play important roles in bioactivity of medicinal plants; thus medicinal values of these plants rely on the embedded phytochemicals and as such produce definite physiological actions on human body. The results obtained from this study thus support the use of Alchornea laxiflora in folklore remedies for the treatment of infections caused by microorganisms.
