“…Regarding plant parts used to prepare medications, the most prominent parts were leaves (37.1%), bark (14.3%) and roots (13.1%) (Fig 3). Such data agrees with other works that recorded 36.4% and 64.5% for leaves, and 23.7% and 7.8% for barks [37, 81].…”

“…The leaves were the most frequently mentioned parts in other studies with 72.5%, 68.2%, 61%, 40%, respectively [82,67,83,84]. This may be due to the fact that leaves are the most abundant and accessible plant parts [81]. From the conservation point of view, the use of leaves is sustainable, since, if the withdrawal of aerial parts is not excessive, will not prevent the development and/or reproduction of the plant [85].…”

Studies in rural communities are important to maintain popular knowledge between generations, as well as to identify new species for pharmaceutical production. Thus, the objectives of this study were to determine which plant species the rural community of Bananal, Mato Grosso, Brazil, uses by calculating the levels of fidelity and concordance regarding species uses among residents and to determine if there is a relationship between the number of known useful plants and levels of education, age, and residence time. Ethnobotanical data was collected from residents of the community through semi-structured interviews in January/December/2016. Species diversity was calculated using Shannon-Wiener, Level of Fidelity (LF), Correction Factor, and the Percentage of Agreement regarding the Main Uses (AMU). Statistical tests were performed using generalized linear models (GLM) in the R environment. The plant use indications were grouped according to the International Classification of Diseases and Related Health Problems (ICD 10). We found 152 species belonging to 130 genera and 67 families. The most frequently used plant parts were leaves, and decoction was the most frequent preparation mode. Strychnos pseudoquina was the species with the highest amount of use indications. The diversity index was 4.5 nats/ind-1. The body system with the most citations was the code XVIII of ICD 10, corresponding to the species: alfavaca, mentraste, terramicina, angelim, fedegoso. Medicinal species with AMU values higher than 25% were: Strychnos pseudoquina, Plectranthus barbatus, Citrus sinensis cv. pera, Cymbopogon citratus. There was a relationship between the number of useful plants and the residence time of the participants. The Bananal community revealed high species richness and the relationship of knowledge showed that the older the residents and the longer their residence time in the community, the more knowledge they acquired.

“…Therefore, the bark of this plant was selected to use in the current study. Using medicinal plants for treatment of many diseases is an interesting alternative way (16) as there are many phytochemical compounds which enable to relieve ailment (17). The pharmacological activities of several plants are from metabolite products existed in the plants (18).…”

In the present study, the fractionated extracts of Sesbania grandiflora bark were prepared and evaluated for their biological activities. The ethyl acetate fractionate (EAF) showed high antioxidant activity along with free radical scavenging and reducing mechanisms. The free radical scavenging antioxidant activity of EAF was 69.3 ± 3.6% where its Trolox equivalent antioxidant capacity was 13.6 ± 0.7 mM/mg. EAF exhibited the reducing power equivalent to ferrous sulfate at 152 ± 2 mM/mg and equivalent to gallic acid at 1.05 ± 0.01 mM/mg. In addition, EAF presented high potential on inhibition of bacterial growth with the minimum bactericidal concentration less than 1 mg/mL. Further isolation of EAF using normal-phase open column of silica gel 60, showed that the fractions eluted with the mixture of chloroform and methanol at the ratios of 4:1, 3:2, and 2:3 possessed antibacterial activity. The recovery activity of total different active fractions was 5% EAF, 20 times less than that of EAF. The chromatogram of EAF from a high-performance liquid chromatography was compared with caffeic acid, catechin, coumaric acid, ellagic acid, gallic acid, quercetin, syringin, naringic acid, trans-cinnamic acid, and vanilic acid. The result demonstrated that one major compound of EAF was gallic acid. These results suggest that the fractionated extracts of S. grandiflora bark contained antioxidant and antibacterial activities.

“…Concernant Balanites aegyptiaca, objet de la présente étude, bien que l'espèce soit écologiquement considérée comme une espèce résiliente adaptée aux différents types de sols et aux conditions climatiques variées (Hiernaux et al, 2006), les risques de diminution du potentiel de production de l'arbre sont réels. En effet, toutes les parties de la plante (racines, feuilles, fruits, écorces, épines, bois) sont utilisées à des fins alimentaires, thérapeutiques, économiques ou socioculturelles (Walter, 2001 ;Elseed et al, 2002 ;Elfeel et Warrag, 2011 ;Chahad et al, 2015 (Gnoula et al, 2008). Les rameaux et les épines sont vert grisâtre devenant brun clair finement pubérulents à tomenteux, mais généralement glabrescents.…”

). Seeds and thorns are also a great socio-cultural importance. The socioeconomic activities observed around the tree products concern fruits, seeds and wood marketing which constitute a socio-economic interest for local community and in particular for women. Conclusion and Application of findings:This study showed that local people in the region of Ouaddaï have a wealth of knowledge and expertise on B. aegyptiaca. The endogenous local knowledge identified and the perceptions constitute a basis for the development of conservation strategies and sustainable use of these genetic resources. Consequently, the availability of products derived from this three should be increased through his domestication and introduction into the existing local farmer production systems.
