Combretum glutinosum Perr. ex DC. (Combretaceae) est une plante médicinale largement utilisée en Afrique par les praticiens traditionnels pour le traitement de divers troubles comme maladies respiratoires, la douleur, paludisme et infections microbiennes. En raison sa large utilisation traditionnelle, dans cette revue, rapports scientifiques publiés sur composition ses propriétés pharmacologiques ont été explorés effectuant recherche documentaire bases données Google Scholar, PubMed,...
Screening of flavonoid compounds in fruit, leaf, stem and root bark extracts Z. leprieurii was achieved by liquid chromatography (LC) coupled with tandem mass spectrometry (MS2). Among the 186 reference tested, four flavonoids were identified one or other organ from each plant (fruit, barks stem): neodiosmin hesperidin all extracts. The presence datiscin reported only leaves while that rutin fruits leaves. Of these flavonoids, three (neodiosmin, rutin) are detected for first time leprieurii....
Hibiscus sabdariffa also known as Roselle is a shrub generally measuring between one and two meters in height. After flowering, white or red calyxes appear, depending on the variety. These are highly prized by African populations for production of drinking juice. Thus, this work was initiated to study thermal effects physico-chemical parameters juice obtained. The pH determined using meter, conductivity meter. Polyphenols were quantified ferric chloride reaction Folin-Ciocalteu's reagent....
Methylene blue (MB) is a phenothiazine derivative used in microbiology, surgery, diagnostics and as sensitizer the photo-oxidation of organic pollutants. These numerous uses methylene could lead to its accumulation wastewater, causing harmful effects on environment living beings. To combat these effects, wastewater treatment processes, particularly physicochemical, were implemented. Adsorption techniques are find new natural, biodegradable inexpensive adsorbents treat colored waste from...
Introduction: Laryngeal cancer is the first of upper aerodigestive tract. Dysphonia, dyspnea and dysphagia are evocative signs. Diagnosis histological squamous cell carcinoma most common type. The objective our study was to discuss epidemiological anatomo-pathological characteristics laryngeal cancers diagnosed in different pathological anatomy cytology (ACP) laboratories Dakar hospitals. Material method: This a retrospective spanning from January 2013 December 2018 at Fann, Aristide Le...
The aim of this study was to investigate the chemical composition essential oils “Covid-Organics” Madagascar (62% Artemisia annua and two other undisclosed medicinal plants) used as curative preventive treatments Covid-19, identify its constituent species. isolated by hydro-distillation from samples (curative preventive) were analyzed GC-FID GC-MS. These mainly dominated camphor (17.9% 11.9%, respectively), spathulenol (4.8% 11.8%, α-acorenol (4.3% 3.7%, (E)-β-caryophyllene (3.4% 4.2%,...
This study determined mineral value and antioxidant activity of Senegal fruits for contributing to improving healthy diet preventing some chronic diseases. Mineral element contents Dialium guineense, Landolphia heudelotti, Mangifera indica, Cyperus esculentus Saba senegalensis, which are widely available consumed, were studied. The results by ICP-OES spectrophotometry after acid mineralization showed highest levels (per 100 g fruits), calcium (158 mg), potassium (1018 magnesium (532 zinc (26...
La valorisation des ressources locales constitue un impératif afin d’atteindre objectifs de développement durable. Cette étude a consisté à évaluer les caractéristiques physiques, chimiques et minéralogiques d’une argile provenant Mbodiène (Sénégal), l’attapulgite, comparativement avec médicament antidiarrhéique, constitué d’attapulgite, dénommé Actapulgite®. L’échantillon d’attapulgite brute été purifié une solution HNO3 1M. Une morphologique effectuée par visualisation la Microscopie...
The fruits of Zanthoxylum leprieurii Guill. & Perr. (Rutaceae) are traditionally used in Africa, particularly Cameroon, as a spice and the treatment sickle cell anaemia. objective this study was to investigate fruit essential oils from different sample locations during their maturation period by using GC GC-MS. Except for one collected Aniak which consisted mainly oxygenated monoterpenes, volatile composition Z. exhibited relative high amounts monoterpene hydrocarbons (61.1-90.9%) such...
Li-ion batteries (Libs) are a mature technology widely used for energy storage in various electronic devices. Nowadays, this has become leading candidate the portable electronics market and electric vehicles due to its good performance. As result, demand Libs containing critical metals, rare earth elements precious metals is increasing day by with accelerated upgrades of consumer electronics, which promotes supply risk many mining resources. In addition, problems associated production...
Our study focused on the valuation of Tchiky clays. This work aims to evaluate its properties explore possible uses in pharmacy. Physico-chemical and mineralogical characterizations were carried out, as well pharmacopoeial tests an evaluation antioxidant activity. Thus, chemical analysis by X-ray fluorescence spectrometry gave silicon (55.65%), iron (15.73%), aluminum (13.53%), potassium (6.05%), titanium (3.98%), magnesium (2.10%), calcium (0.82%). diffraction showed presence kaolinite,...
Antisepsis and disinfection have always played an important role in the fight against infectious diseases. The use of these products has been effective breaking chain transmission microorganisms. Today, with advent COVID-19, main recommendations are, among other things, physical distance antiseptic products, including hydro-alcoholic products. In Senegal, poor regulations on acquisition distribution antiseptics disinfectants, this situation led to a proliferation disinfectants national...
