Roots of Aconitum carmichaelii are used in Asian countries due to its content bioactive alkaloids. In the production root preparations, tons leaves usually discarded, leading a huge waste herbal material. The aim this study is investigate polysaccharides these unutilized leaves. A neutral polysaccharide (AL-N) appeared be mixture heteromannans, and two purified acidic (AL-I-I AL-I-II) were shown pectins containing homogalacturonan backbone substituted with terminal β-Xylp-units. AL-I-I...
Abstract An ethnopharmacological survey was carried out to collect information on the use of seven medicinal plants in rural areas nearby regions Bamako, Mali. The were Opilia celtidifolia , Anthocleista djalonensis Erythrina senegalensis Heliotropium indicum Trichilia emetica Piliostigma thonningii and Cochlospermum tinctorium About 50 medical indications reported for these traditional medicine. most frequent ailments malaria, abdominal pain dermatitis. highest number usages treatment...
The Gourma population has a vast knowledge of medicinal plants, as demonstrated in this survey carried out between 1999 to 1991 with herbalists, traditional healers and resource persons, well 424 households informants. This investigation includes 42 species major use native medicine for rural health care the region. These plants belong 23 families are used treatment digestive disorders, malaria, skin diseases, cardiovascular respiratory complaints. identified potential source new bioactive...
Plants are used in different ways Mali, among those as medicine and food. The monitoring of metals the plants is great importance for protecting public from hazards possible toxic effects also informing population about nutritional value plants. concentrations some essential metal ions were surveyed seven medicinal edible Mali. Dry ashing plant material subsequent use atomic absorption spectrophotometry analytical methodologies used. Iron, manganese, zinc found high plants, i.e., 1.4 1.5...
Polysaccharides from plants have been the subject of study for a very long time, but mainly their physical properties and industrial use based on these properties. Over last 20 years there has an ever increasing interest in biological activity biomolecules. These studies became possible as result scientific development isolation, purification characterisation methods concomi-tant with fairly simple vitro tests, especially effects immune system. The growing acceptance knowledge to be gained...
An ethnopharmacological survey was carried out to collect information about the use of six medicinal plants in regions around Siby and Dioila, Mali. The investigated were Biopyhtum petersianum, Cola cordifolia, Combretum molle, Opilia celtidifolia, Parkia biglobosa Ximenia americana. More than 60 medical indications reported for these traditional medicine. most frequently ailments malaria (25.6%), different types pain (14.0%) dermatitis (7.4%). main forms preparation decoction (58.1%)...
Abstract Background Although, medicinal plants have been important for women’s health historically, the knowledge about such use during pregnancy in developing countries is limited. This first quantitative, ethnobotanical study on Malian of and attitudes towards pregnancy. The aim was to describe according indications evaluate potentially safety use. overall preserve valuable information reproductive future. Methods Data collected through structured interviews 209 pregnant women or mothers...
The interaction between a pectin type polysaccharide fraction, PMII, isolated from the leaves of Plantago major , and human complement was tested in two different hemolytic complement‐fixation tests addition by elisa methods detecting complement‐activation products. Sera were used as source 10 arbitrary volunteers, individually pool. designed to measure concentration necessary inhibit 50% hemolysis (ICH 50 ). for products measured AU/mg using fully activated serum standard. We observed more...
Hot water‐soluble polysaccharides were extracted from field colonies and suspension cultures of Nostoc commune Vaucher, flagelliforme Berkeley et Curtis, sphaeroides Kützing. Excreted extracellular polymeric substances (EPS) isolated the media in which grown. The main monosaccharides colony three species glucose, xylose, galactose, with an approximate ratio 2:1:1. Mannose was also present, but levels varied among species, arabinose appeared only N. flagelliforme. compositions cellular EPS...
AbstractIdentification of 123 species, belonging to 50 families, used for wound healing in the Bamako region Mali, was performed this study. The fifteen species that were most frequently cited by traditional healers subjected chemical and biological studies. Water extracts screening effects on human complement system vitro. monosaccharide composition total carbohydrate content also determined. All showed system, but from Biophytum petersianum Klotzsch., Pterocarpus erinaceus Poir, Podaxon...
