... (Fabaceae-Caesalpinioideae) is one of these plant resources, present in arid regions of West and Central Africa from Senegal and Gambia to Sudan [11], whose fruits are underexploited. The sweet pulp of the fruit is consumed raw at maturity while the seeds are almost unexploited [12,13]. However, the cooked seeds are sometimes used to thicken soup for human consumption [13]. ...
... C. tinctorium and C. planchonii are two wild multipurpose plant species that spread across the dry regions of West Africa [26,35]. As previously described in [24,36], they are both xeromorphic and subshrubs, commonly used by rural communities for various purposes such as food, medicine for humans and animals, dye and handicraft [24,35]. Their woody subterranean rootstocks [37,38] are the main parts of these species used. ...
... Amuti (1980) gave the first description of KG floral biology and deduced from their observations that the crop is a selfpollinated plant with white or purple flowers. Obasi and Ezedinma (1994) focused on floral biology while Kafoutchoni et al. (2021b) went further to study the floral and fruiting phenology, stigma receptivity, pollen viability, and germinability, to devise insights to designing hybridization protocol that guarantees maximum success in the development of breeding lines. Similar research efforts in pigeon pea, which previously had a low success of artificial hybridization (Kalve and Tadege, 2017), has led to the development of hybrid varieties with 25-69% yield superiority over the local cultivars in India (Saxena, 2015). ...
... is study was conducted to evaluate the 90-day oral toxicity of C. spinarum, a plant used for many purposes in Togo and the West African region mainly as an aphrodisiac [29]. Based on previous toxicological results [18], a limit test of 90-day oral toxicity test was performed at 500 and 1000 mg/kg according to OECD 408 guidelines. ...
... Une Analyse Factorielle des Correspondances (AFC) a été réalisée avec le logiciel R 3.2.5 [28] pour établir les liens qui existent entre les catégories d'usages de l'espèce et les ethnies. En effet, l'ethnie reste un des facteurs majeurs qui expliquent la variation des usages des plantes entre les communautés [17]. L'impact de l'utilisation des différents organes sur la conservation de l'espèce a été mesuré par le biais de la détermination du degré de menace. ...
... La grande majorité de ces études ont déjà montré les propriétés antioxydantes des tanins, des flavonoïdes et des polyphénols. Ces composés connus pour leur capacité de piégeage des radicaux libres (Kanfon et al., 2018) peuvent prévenir le développement de nombreuses maladies chroniques (Vadivel et al., 2011). Ils sont indispensables pour réduire le stress oxydatif après un AVC, puis permettre une régénération du tissu cérébral, résorber la lésion et donc les déficits moteurs (Quintard, 2016). ...
... In recent decades, ethnobotanical studies have analyzed the dynamics of people-plant relationships under different perspectives [2]. Understanding the dynamics of traditional knowledge of people could provide significant implications, notably the checklist of plants used by people, identification of their phytochemical and biological properties, optimization of their uses, and exploration of new insights into the impacts of usages on their conservation status [3]. On the other hand, understanding how and why people select plants for a wide range of uses has been in response to a repeated call for theory-inspired and hypothesis-driven research to improve the rigor of ethnobotany as a discipline [4]. ...
... High amounts of β myrcene characterized this essential oil, and alpha and β cariophylene. Both compounds have been identified exhibiting promising acaricidal activity against V. destructor Dedome et al., 2017;Kouache et al., 2017;Maggi et al., 2010;Ruffinengo et al., 2005;. Monoterpenes, such as myrcene, have shown synergistic acaricidal activity against the plant pest like the red spider mite (Tetranychus urticae) (Cavalcanti et al., 2010), demonstrating a variable anticholinesterase activity and acaricidal activity by contact or suffocation. ...
