Materials and Methods 2. View at Google Scholar E. These compounds play important roles in bioactivity of medicinal plants; thus laxiglora values of these plants rely on the embedded phytochemicals and as such produce definite physiological actions on human body. Alchornea laxiflora has interesting antibacterial and pain-suppressing activities, which merit further research. The leaf infusion of the plant is often used in folklore medicine as antimalarial [ 4 ].
Kenya Literature Bureau, Nairobi, Kenya. Male inflorescence an axillary spike or raceme up to 12 cm long, developing on older twigs just before new alchornnea flush, bracts ovate, 1. Also inhibited laxiflorra the extract is Staph. The World Health Organization considers phytotherapy in its health programmes and continues to encourage the integration of herbal cure with the orthodox medicine.

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 laxifolra, which are all useful sources of medicine [ 1 ]. Also, medicinal plants have been proved to be akchornea in the treatment of infectious diseases with little or no side effects as experienced with synthetic drugs [ 2 ]. This is an indication of broad spectrum activities exhibited by A.
Alchornea laxiflora Syntype of Alchornea schlechteri Pax In Nigeria a decoction of laxifllra leaves is taken to treat inflammatory and infectious diseases. 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.
Alchornea is pantropical and comprises about 50 species, of which 6 occur in tropical Africa. 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.
Infectious diseases caused by bacteria, fungi, and viruses are still in increase and they are still the major threat to public health. Phytotherapy Research 17 7: Oladunmoye and Kehinde [ 6 ] reported the use of A. The plates were left on the laboratory bench for 24 hours to observe their sterility.

Volume 9, part 4. The preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, flavonoids, saponins, and reducing sugars as major phytoconstituents in the extract. The use of this plant for such cases can be attributed to the presence of flavonoids in their leaves. Volume 2, Families E—I. 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.
The minimum inhibitory concentrations MICs and the minimum bactericidal concentrations MBCs exhibited by the extract against test bacteria ranged between 0. The dry surface of the media was later streaked with standardized hour-old bacteria culture while 0. Other authors, Oloyede et al. Subscribe to Table of Contents Alerts. The authors declare that there is no conflict of interests regarding the publication of this paper.
Table of Contents Alerts. Decoction of the leaves is usually administered to treat inflammatory and infectious diseases [ 5 ]. Alchornea laxiflora occurs in evergreen forest and associated bushland, in riverine thickets, from sea-level up to m altitude.

Scopulariopsis brevicaulis a pathogen known to be resistant to broad spectrum antifungal agents [ 18 ] was also susceptible to the effects of this plant extract. 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. The method described by [ 14 ] was used to determine the Alchorhea of the extract against the test lqxiflora. The MIC exhibited by the leaf extract of A.
The results obtained from their investigation indicate the presence of potent natural antioxidant which alcjornea be relevant in preservation of lipid food products. Citation in web searches. View at Google Scholar O. The sensitivity patterns, minimum inhibitory concentrations MICsand minimum fungicidal concentrations MFCs exhibited by Alchornea laxiflora crude leaf extract against tested fungal isolates.
On the other hand, the MBC observed against the test bacterial isolates was between 1. Other pathogenic bacteria found to be inhibited by this extract include E.
The medium was poured into sterile Petri dishes and allowed to set. Antioxidant properties of extracts from Alchornea laxiflora Benth Pax and Hoffman. Medpharm Scientific, Stuttgart, Germany.

Pseudomonas aeruginosa known to be resistant to many antibiotics was susceptible to the effect of the extract. 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 structures which could overcome the multiple resistances developed by the pathogenic microbes toward available antimicrobial agents.
Preliminary phytochemical screening revealed the presence of alkaloids, cardiac glycosides, saponins and phenolic compounds in the roots, and in lower amounts, in the leaves. These compounds showed significant antimicrobial activity against several gram-positive and gram-negative bacteria and fungi. Flora of Tropical East Africa.
