These compounds showed significant antimicrobial activity against several gram-positive and gram-negative bacteria and fungi. View at Google Scholar H. In Nigeria a decoction of the leaves allchornea taken to treat alchonrea and infectious diseases. This is an indication of broad spectrum activities exhibited by A.
Alchornea laxiflora 2 Anthocyanins x – 15k – gif www. Alchornea laxiflora 2 Anthocyanins x – 24k – gif www. The final concentrations regimes of 0. The results obtained revealed the inhibition of both Gram-positive and Gram-negative bacteria while a wide range of fungi used were susceptible to the effects of the plant extract.
Also, medicinal plants have been proved to be effective in the treatment of infectious diseases with little or no side effects as experienced with synthetic drugs [ 2 ]. The preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, flavonoids, saponins, and reducing sugars as major phytoconstituents in the extract.
Among the Yorubas of Southwestern Nigeria, A.
Alchornea laxiflora (Benth.) Pax
The antimicrobial effects of the leaf extract of A. The authors declare that there is no conflict of interests regarding the publication of this paper. Alchornea is pantropical and comprises about 50 species, of which 6 occur in tropical Africa. The antimicrobial activities of A. The medium was poured into sterile Petri dishes and allowed to set. Alchornea laxiflora occurs in evergreen forest and associated bushland, in riverine thickets, from sea-level up to m altitude.
The results obtained from this study thus support the use of Alchornea laxiflora in folklore remedies for the treatment of infections caused by microorganisms. The results obtained from their investigation indicate the presence of potent natural antioxidant which may be relevant in preservation of lipid food products.
Oladunmoye and Kehinde [ 6 ] reported the use of A.
Introduction 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 ]. Samples were taken from plates with no visible growth in the MIC assay and subcultured onto freshly prepared nutrient agar plates for bacteria and malt extract medium for fungi. There are 6 citations in Afrirefs related to Alchornea laxiflora Benth.
Alternaria species is a plant pathogen capable of causing hay fever in humans leading to asthma [ 16 ]; thus, the extract may be a prototype for future drugs in the management of respiratory tract complications such as asthma. Decoction of the leaves is usually administered to treat inflammatory and infectious diseases [ 5 ]. Subscribe to Table of Contents Alerts. 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.
Materials and Methods 2. The MBC or MFC was taken as the concentration of the extract that did not show any bacterial or fungal growth on fresh agar medium. From the ethyl acetate soluble fraction of the crude methanolic leaf extract the flavonoids quercetin and the quercetin-related compounds rutin and quercitrin were isolated.
The sensitivity patterns, minimum inhibitory concentrations MICsand minimum fungicidal concentrations MFCs exhibited by Alchornea laxiflora crude leaf extract against tested fungal isolates. Infectious diseases caused by bacteria, fungi, and viruses are still in increase and they are still the major threat to public health. The fungal isolates used were Aspergillus nigerAspergillus fumigatusAspergillus glaucusAspergillus flavusFusarium species, Penicillium expansumAlternaria species, Trichophyton interdigitaleTrichophyton mentagrophytesTrichophyton rubrumPenicillium camembertiTrichoderma species, Scopulariopsis brevicaulisPenicillium italicumCandida albicansand Candida pseudotropicalis.
Medicinal plants of East Africa. Scopulariopsis brevicaulis a pathogen known to be resistant to broad spectrum antifungal agents [ 18 ] was also susceptible to the effects of laxfilora plant extract. The leaf sap and root decoction are drunk to treat pain in neck and shoulders.
The antioxidant activities of the leaves are interesting as well, and more research is needed to elucidate the effectiveness under different conditions.
The anti-oxidant activity of the root and leaf extracts have been compared with that of the standard anti-oxidant butylated hydroxyanisole.
