The biologically active components of plant extracts and essential oils are used in most of the pharmaceutical industries because of their antimicrobial, antifungal, and antiviral properties. This is one of the reasons why Yoruba tribe of Alchorna Nigeria referred to A. Subscribe to Table of Contents Alerts.
It is also a common ingredient in herbal antimalarial preparations. 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.
In Nigeria a decoction of the leaves is taken to treat inflammatory and alxiflora diseases. There are 2 Wikipedia citations related to Alchornea laxiflora Benth.
On the other alchorrnea, the MBC observed against the test bacterial isolates was between 1. 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. Oladunmoye and Kehinde [ 6 ] reported the use of A. The results obtained from their investigation indicate the presence of potent natural antioxidant which may be relevant in preservation of lipid food products.
Alternaria species is a plant pathogen capable of causing hay fever in humans leading to asthma [ 16 ]; thus, the extract may be a lxiflora for future drugs in the management of respiratory tract complications such as asthma.
Further studies are ongoing in our laboratories on the mechanism s of actions of the extract on bacteria and fungi found to be susceptible to the effects of the plant extracts. Alchornea is pantropical and comprises about 50 species, of which 6 occur in tropical Africa. Among the Yorubas of Southwestern Nigeria, A.
The plates were allowed to stand on the allchornea bench for one hour to allow for proper diffusion of the extract solution into the medium. Volume 2, Families E—I. Small branches are used as chew sticks. Kenya Literature Bureau, Nairobi, Kenya. The phytochemical analysis of the leaf extract of A. There are 47 book citations related to Alchornea laxiflora Benth. The susceptibilities of these pathogens to the leaf extract of A. 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 albicansalchorea Candida pseudotropicalis.
The spores were later standardized before use. These were later examined for the presence or absence of growth. 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.
Scopulariopsis brevicaulis a pathogen known to be resistant to broad spectrum antifungal agents [ 18 ] was also susceptible to the effects of this plant extract. Euphorbiaceae, subfamilies Phyllantoideae, Oldfieldioideae, Acalyphoideae, Crotonoideae and Euphorbioideae, tribe Hippomaneae.
Alchornea laxiflora (Benth.) Pax
The minimum inhibitory concentrations as well as the minimum bactericidal concentrations were determined. The phytochemical assay of the leaf extract of A. The sensitivity patterns, minimum inhibitory concentrations MICsand minimum bactericidal concentrations MBCs exhibited by Alchornea laxiflora crude leaf extract against tested bacterial isolates.
Efforts are still ongoing to search for new biologically active compounds from natural sources as new antimicrobial agent with a view to discovering new chemical allchornea which could overcome the multiple resistances developed by the pathogenic microbes toward available antimicrobial agents.
Evidence-Based Complementary and Alternative Medicine
The preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, flavonoids, saponins, and reducing sugars as major phytoconstituents in the extract.

Medpharm Scientific, Stuttgart, Germany.
The extract was able to inhibit the growth of these pathogenic dermatophytes which is an indication that extract laxifoora this plant is a good source of antifungal compound that can be employed in pharmaceutical industries for the formulation of potent antifungal drugs.

Also alchornra by the extract is Staph. 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. Journal of Ethnopharmacology 74 3: Abstract Alchornea laxiflora leaf extract was tested against a range of microorganisms using standard microbiological methods for antimicrobial activities.
As far as alfhornea know, up to this point, Alchornea laxiflora leaf extract is a potent source of antibacterial and antifungal compound and compared favourably with the positive controls streptomycin-antibacterial and Nystatin-antifungal used in this study. The MIC was taken as the lowest concentration that will prevent the growth of the test organisms. Antioxidant properties of extracts from Alchornea laxiflora Benth Pax and Hoffman.
Laxilfora phytochemical analyses of A. Citation laxifloga web searches.
Aspergillus species which were among laciflora fungal isolates used and known to cause aspergillosis mainly bronchopulmonary aspergillosis were susceptible to this plant extract. The leaf extract has been reported to contain alkaloids, flavonoids, saponins, tannins, carbohydrates, cardioactive glycosides steroids, phenols, and reducing sugars as phytochemicals resident in the plant.
The method described by [ 14 ] was used to determine the MIC of the extract against the test isolates.
