Ectomycorrhizas and Putative Ectomycorrhizal Fungi of Afzelia Africana Sm. and Uapaca Guineensis Mull. Arg. in Southern Senegal
Ectomycorrhizas and putative ecto- mycorrhizal fungi of Afxelia africana Sm. and Uapaca guineensis Müll.. Arg. in southern Senegal BY D. THOEN'i2 AND A. M. BA' 'Laboratoire de Microbiologie des Sols, ORSTOM, B.P. 1386, Dakar, Senegal 'Fondation Universitaire Luxeinbourgeoise (FUL), rue des Diporte's, No. 140, B-6700 Arlon, Belgium (Received 3 April 1989; accepted 18 August 1989) SUMMARY Ectomycorrhizas and ectomycorrhizal fungi of Afielia africana Sm. and Uapaca guineensis Müll. Arg. are reported in forests of southern Senegal. Ectomycorrhizas occurred in dry and wet conditions, at different soil contents of available phosphorus (0-17.5 pg g-'). U.guineensis was confined to groundwater forests. Individual trees had both ecto- and endomycorrhizas, A. africana grew scattered in semi-evergreen and riverside forests, whereas in the woodland it formed larger patches and could dominate the canopy. Eighteen putative ectomycorrhizal fungi grew under U..guineensis and thirty-one under A. africana. Only six species were common to both trees, indicating an ecological and/or taxonomical selection. The fungi belonged to the following Orders : Russulales (16), Boletales (2), (2), (1l), Agaricales (9), Cnntharellales Sclerodermatales Hymenogastrales (l), Gnutieriales (l),Aphyllophorales (1). Some of them had a wide Sudano-Zambezian or Guineo-Congolian distribution and reached their northern limit in Senegal.

In Vitro Antimalarial Activity of the Ethanol Extracts of Afzelia Africana and Cassia Alata Commonly Used As Herbal Remedies for Malaria in Ghana
ISSN 2394-966X International Journal of Novel Research in Life Sciences Vol. 2, Issue 6, pp: (10-16), Month: November-December 2015, Available at: www.noveltyjournals.com In vitro antimalarial activity of the ethanol extracts of Afzelia africana and Cassia alata commonly used as herbal remedies for malaria in Ghana 1Vigbedor Bright Yaw, 2Osafo Acquah Samuel, 3Ben Adu Gyan B, 4Lotsi Bertha Department of Chemistry, Kwame Nkrumah University of Science and Technology, Kumasi-Ghana Department of immunology, Noguchi memorial institute for medical research, College of health sciences, University of Ghana Abstract: In this study, two commonly used plants were investigated for their antimalarial activities against the 3D7 strain of the Plasmodium falciparum parasite.Ethnobotanical survey in the Sekyere central district revealed the usage of the aqueous decoction of the stem bark of Afzelia africana and the leaves of Cassia alata in combination therapy for the treatment of malaria; however, its efficacy has not been scientifically proven. In this study, the stem bark of A. africana and the leaves of Cassia alata were investigated for their antimalarial activity against the 3D7 strain of the Plasmodium falciparum parasite. This was done by employing the WHO microtest assay (Mark III). These were compared with artesunate-amodiaquine. The results indicated that, the standard drug, Artesunate-amodiaquine was the most active with an Inhibitory Concentration (IC50) of 0.313μg/ml this was followed by Afzelia africana, and Cassia alata with IC50 values of 2.954μg/ml, and 17.270μg/ml respectively. This study has provided scientific evidence for traditional usage of Afzelia africana and Cassia alata as effective remedy for the treatment of malaria in Ghana. -

However, species-specific relationships between climate and tree-ring stable isotopes have not yet been studied in riparian forests in the savannas of West Africa. Four cross-dated discs, each of Afzelia africana Sm. (evergreen) and Anogeissus leiocarpus (DC.) Guill. & Perr. (deciduous) in the humid (HSZ) and dry (DSZ) savanna zones of the Volta basin in Ghana were selected from a larger tree-ring dataset to assess the relationships between the tree-ring carbon isotope composition (d13C values) and climatic parameters. -

Accepted 27th November, 2012 Forest degradation has been worsening over the past years by the numerous populations seeking a means of living, without respecting minimum conservation rules. Converting forests into timber is another cause of deforestation. In Wari-Maro, a protected forest, timber tree species such as, Afzelia africana, Pterocarpus erinaceus, Khaya senegalensis, Pseudocedrela kostchyi, Ceibapentanda and Chlorophora excels were exploited for commercial use in Benin. The study aimed to assess the status of timber (commercial timbers) species in Wari-Maro forest in Benin. The methodology used was based on satellite images processing for identification of the vegetation types. The sampling plots were established in each type of vegetation for assessing the different timbers species listed above. The results show that Afzelia africana was less than three plants per hectare and the extreme classes were not represented. The same results were obtained with Khaya senegalensis. The results have also shown that P. erinaceus and P. kostchyi were represented in all classes with the number of plants less than 8 per hectare. -

In this study, the leaves of Afzelia xylocarpa (Kurz) Craib. were investigated for biological activity, and their active substances were determined. Extracts of A. xylocarpa leaf exhibited concentration-dependent phytotoxic activity against the seedling length of Lepidium sativum L., Medicago sativa L., Phleum pratense L., and Echinochloa crus-galli (L.) P. Beauv. Bioassay-guided fractionation of the A. xylocarpa leaf extracts led to isolating and identifying two compounds: vanillic acid and trans-ferulic acid. Both compounds were applied to four model plants using different concentrations. The results showed both compounds significantly inhibited the model plants’ seedling length in a species-dependent manner (p < 0.05). The phytotoxic effects of trans Citation: Krumsri, R.; Ozaki, K.; -ferulic acid (IC50 = 0.42 to 2.43 mM) on the model plants were much greater than that of vanillic Teruya, T.; Kato-Noguchi, H. -

Original Research Article Conservation and Restoration Of
Original Research Article Conservation and Restoration of Endangered Plant Species in the Tropical Forests ABSTRACT Indiscriminate charcoal productions, timber harvesting, demand for farmlands and overgrazing have aggravated land degradation process in the tropical regions. At each point of this cycle, species are lost and biodiversity is obtainable only in the National Parks, Game reserves, Forest reserves, Wildlife sanctuaries. Forests and its resources are important assets that the tropical regions can sustainably manage for its renewable potentials, environmental benefits and socio- economic importance to mankind. Thus, this paper aim at reviewing of past research works to provide profound solutions for conservation and restoration of forests and its products in the mid of financial shortcoming among the developing nations in the tropical regions. Based on this review, endangered plant species (such as- Prosopis africana, Parkia biglobosa, Khaya senegalensis, Gleditsia assamica, Gymnocladus assamicus and Aquilaria malaccensis among others) can be restored; and genetic heredity (with qualitative characteristics) can be sustain for generational use if only we will all ignore the voice that “demands high financial resources for the management of endangered species before it can be conserved and restored”. Even without the provision of financial resources for conservation and restoration of endangered species, with high interest and euphoria among the youths, the young populace can conserved and restored the tropical forests and its biodiversity in the regions. This can be achieved by frequent inclusion of youths in decisions making and the use of non-formal education methods (such as drama, playlet, music concerts among others). Therefore, it is recommended that communities around forest reserves in the tropical regions should be economically empowered, so that they can have alternative sources of livelihood that are biodiversity friendly, thus, reducing their dependence on forests and forest products.
