Abstract
In Africa and Cameroon in particular, people tend to use medicinal plants as the first approach to cure their illness or disease. In order to improve the safety and the progressive integration of those plants in our health systems, it is important to set a system and protocol that would permit an easy characterization, quality and safety control of medicinal plants through a standardization of their recipes. Thus, we develop a Pharmacognosy and phytochemical study of Albizia ferruginea pulps and complete by a monograph for each plant. A macroscopic and microscopic analysis of the drugs is done, followed by a study of the weight loss due to desiccation. Furthermore, the ratio of ashes in the powders was investigated in conformity with the European pharmacopeia. We further extract and perform a phytochemical screening. From the macroscopic analysis, it is observed that the pulp was strong, fibrous crack and powder brown with an aromatic smell. The micrographic analysis shows the presence of various tissues such as suber, fiber, liber, sclerotic cells as well as the calcium oxalate. The ashes percentage of A. ferruginea powder is 1.16%, whereas the weight loss due to desiccation is 7.6 % and inflation indices, 4 mL. The phytochemical screening showed the presence of alkaloids, flavonoid, polyphenols, mucilages, anthocyanins, and saponins. The information gathered throughout this study will contribute to the fast identification, quality control, and characterization of A. ferruginea pulps. Key words: Standardisation, pulps, quality control, Albizia ferruginea.
Highlights
Death per year and causes for more than half the dead casualty occurring in Africa (Organisation Mondiale de la Sante, 2006)
The vegetal material consists of A. ferruginea pulps harvested on February 1, 2016, at Eloundem, located at almost 10 km from the Yaounde city center
The pulps were dry for a week in an ambient environment, followed by a grinding to a granular powdered form
Summary
According to the World Health Organisation (WHO), infectious diseases are causes for more than 17 million. Death per year and causes for more than half the dead casualty occurring in Africa (Organisation Mondiale de la Sante, 2006). Those infectious diseases are rapidly spraying and causing more skin conditions in the continent. It is reported that up to 80% of African regularly use traditional medicine (Observatoire de la sante en Afrique, Medecine traditionnelle, Revue du bureau regional de l’OMS pour l’Afrique, 2003). AbondoNgono et al (2015) reported in 2012 on a census of traditional healers in the Centre region of Cameroon. They launched the mapping of Cameroonian traditional healers (Abondo-Ngono et al, 2015). The standardization reference of the powdered pulps of A. ferruginea was used
