“…En effet, les thérophytes adaptent leur cycle de développement à la période favorable qui correspond à la saison des pluies. Elles ont un cycle très court, parfois de quelques semaines comme chez les espèces du genre Boerhavia (Noba et al, 1994) et du genre Corchorus (Mbaye et al, 2001). D'autres traits concernant l'annualité des plantes, la croissance, la résistance aux perturbations ou encore la longévité peuvent caractériser les communautés d'adventices ou de plantes localisées dans des environnements changeants.…”

RESUMĒCe travail constitue une première étude de la flore des systèmes agropastoraux dans la communauté rurale de Mlomp. Cette étude est réalisée par la méthode des relevés phytosociologiques. Elle a été entreprise pour déterminer la structure de la flore (spectres taxonomique, biologique et chorologique) et l'influence du système d'exploitation des terres sur la flore. Les résultats indiquent que cette flore globale est constituée de 158 espèces réparties dans 91 genres et 37 familles. Dans cette flore, 6 Familles principales regroupent plus de 3/5 (62,66%) des espèces : les Poaceae (26,6%), les Fabaceae (12,02%), les Cyperaceae (6,96%), les Malvaceae (6,96%), les Convolvulaceae (5,06%) et les Rubiaceae (5,06%). Cette flore est caractérisée par une prédominance des thérophytes (77,21%) avec toutefois la présence de phanérophytes (9,49%), d'hémicrytophytes (7,6%), de géophytes (4,43%) et de chaméphytes (1,27%). Cette flore est composée, pour l'essentiel, d'espèces africaines (53,2%), pantropicales (26,58%) et d'espèces afro-asiatiques (6,96%). La flore des pâturages est plus diversifiée que celle des écosystèmes cultivés. Par contre, le système d'exploitation n'influe pas fortement sur les spectres biologique et chorologique.

“…Genus Corchorus consists of annual or short-lived perennial herbs and shrubs with many agriculturally important species. It consists of some forty species of which about thirty are found in Africa (Mbaye et al, 2001). In Benin, it is represented by five species Corchorus aestuans L., Corchorus fascicularis Lam., C. olitorius L., Corchorus tridens L. and Corchorus trilocularis L. (Akoegninou et al, 2006).…”

Corchorus olitorius L. which belongs to Tiliaceae family is a cultivated herbaceous plant highly consumed as traditional leafy vegetables in Benin. Extracts from samples of different morphotypes leaves of this species were analysed for their phytochemical compositions, antioxidant and cytotoxicity activities. On each sample extract, qualitative phytochemical tests were used to detect the presence of bioactive molecules and evaluate their cytotoxicity using brine shrimp lethality bioassay. Antioxidant activity was assessed using the 2,2-diphenyl-1-picryl-hydrazyl assay. Phytochemical screening revealed the presence of several phytochemical compounds in all samples of morphotypes studied but these have not a similar profile. Morphotypes with shiny rounded leaves have more phytochemicals (58% of phytochemicals compounds) than the other samples. Analysis of the potential antioxidant reveals a first category of morphotypes with high potential antioxidant capacity ranged from 27,859 to 32,985 mM EAA/g followed by second class of morphotype which ranged from 17,527 to 23,098 mM EAA/g . Regular consumption of C. olitorius such as varieties with rounded and non-shiny leaves, varieties with elongated and shiny leaves, varieties with red stems, varieties with elongated and nonshiny leaves with lateral lobes, would be useful for the treatment of various diseases induced by free radicals. The LC50 of morphotypes C. olitorius varies between 0.78 and 3.125 mg/ml indicating non toxicity. From this study, results justify the use of some morphotypes of C. olitorius in traditional medicine. Hence, these morphotypes are nutraceuticals leafy vegetables that must be promoted through development of food based products.

“…Corchorus L. species commonly referred to as Jute belongs to the family Tiliaceae. Mbaye et al (2001) reported that the genus contains forty species throughout the tropics. Edmonds (1991) stated that thirty species are found in Africa and four species in Nigeria.The species found in Nigeria include Corchorus aestans, Corchorus tridens, Corchorus fascicularis and Corchorus olitorius.…”

“…It is of high socio-economic importance especially in western Nigeria where the livelihood of millions of local farmers depends on Corchorus production and utilization. Various species of this genus have been reported to be of economic and systematic importance (Mbaye et al, 2001).…”
