Book Description
Une enquête ethnobotanique effectuée dans les îles de la Grande-comore et d’Anjouan, a permis de recenser 44 plantes utilisées en médecine traditionnelle. L’intérêt de ce travail s’est porté plus particulièrement sur les plantes utilisées dans le traitement du paludisme. Après évaluation sur des cultures in vitro de Plasmodium falciparum, trois plantes ont été sélectionnées pour une étude phytochimique et pharmacologique. Des feuilles de Flueggea virosa ont été isolés huit composés, dont cinq décrits pour la 1e fois dans la plante. Quatre composés phénoliques : la rutine, l’acide gallique, le gallate de méthyle, la bergénine ; et quatre alcaloïdes : deux de type sécurinine, un alcaloïde indolique de type β-carboline, et un alcaloïde indolomonoterpénique. Le gallate de méthyle est le composé le plus actif de Flueggea virosa (CI50 = 2,6 μg/ml). Suite à ce résultat, une synthèse d’acides phénols et d’esters correspondants a été réalisée. Les esters de l’acide gallique, l’ester méthylique de l’acide caféïque et les esters de l’acide protocatéchique présentent des activités intéressantes. L’extrait chlorométhylénique des parties aériennes de Piper capense, nous a permis d’isoler cinq composés, parmi lesquels 2 composés nouveaux : les Kaousines A et B. La décoction des parties aériennes de Flacourtia indica a permis d’isoler 3 composés, l’homaloside D, le poliothrysoside et le pyrocatéchol, décrits pour la 1e fois dans la plante. Les trois composés montrent des activités antiplasmodiales intéressantes (CI50 = 2 et 3 μg/ml). Les extraits de Flacourtia obtenus après biotransformations montrent une modification des profils chromatographiques, mais pas de gain d’activité antiplasmodiale par rapport à la décoction.

Book Description
This volume in the series is devoted to Africa, a continent that possesses a vast treasure of medicinal plants and has produced some exclusive materials for the world market. This volume is expected to strengthen the medicinal plant sector in African countries by making comprehensive information on medicinal and aromatic plants available to policy-makers and entrepreneurs. It can be used to frame effective policies and create an environment conducive to the growth of the plant-based medicine industry, bringing economic benefit to African nations. It will help health organizations to improve the health of their people by using their own resources and a less expensive system of medicine, which is accepted by African society. It could also lead scientific communities to increase R&D activities in the field.

Book Description
The African Herbal Pharmacopoeia (AfrHP) provides comprehensive, up to date botanical, commercial and phytochemical information on over fifty of the most important African medicinal plants. The technical data were made on plant samples sourced from across the continent. These monographs prepared by leading African scientists, have been reviewed by international experts. Additional data includes micro morphology of the plant material, distribution maps and TLC Chromatograms. These data are crucial for producers, collectors and traders in medicinal plants and extracts as well as researchers, manufacturers and practitioners. The scope, quality and standard of these herbal monographs are comparable to those prepared in Europe, North America and Asia. Whilst this is the very first edition, it is being proposed to proceed to a second edition, quickly, as more plant species will be covered.

Book Description
This scheme meets the need for a standard yet adaptable system of geographical units for use in recording plant distributions and arranging specimens. Because a purely political arrangement cannot meet all the needs of botanists, the scheme's arrangement compromises between a politically and a phytogeographically oriented system. It identifies geographic units worldwide in a four-level hierarchy, incorporating continents, regions, provinces and countries. Each geographical unit at each level has its own numeric or alphanumeric code. The scheme is presented in five tables, the recognized geographical units are shown in 17 maps, and a gazetteer relates over 2,100 names to the overall system.

Book Description
This volume brings together a collection of papers by some experts in medicinal plants. It is presented as a contribution to clarifying the many policy and technical issues associated with the conservation, use, production and trade of medicinal plants. This publication draws attention to the huge contribution of medicinal plants to traditional and modern health care systems, but also alert the readers on the many problems and challenges facing their sustainable development, such as: assessment and management of the medicinal plant resource base; best harvesting and processing practices; trade issues and aspects dealing with the intellectual property rights on traditional medicine by indigenous peoples. The use of this document will help raise the awareness on medicinal plants as an important forest resource, and will help ensure that medicinal plants are adequately included in forest conservation and utilization programmes.
