Article de synthèse EthnobotaniqueNotes ethnobotanique et phytopharmacologique sur Ricinus communis L.Résumé : Le ricin (Ricinus commmunis) est un arbuste appartenant à la famille des Euphorbiacées. Il se trouve un peu partout dans le monde, mais il se concentre surtout dans les régions tropicales. Cette euphorbiacée est connue pour sa tolérance aux conditions abiotiques défavorables ainsi que par ses vertus médicinales et thérapeutiques très intéressantes vu les activités pharmacologiques des composés phyto chimiques présents dans les extraits de la plante (les flavonoïdes, les alcaloïdes et les tanins). De même, le ricin présente un composé très toxique : la ricine, qui, associée à des anticorps monoclonaux, est utilisée en thérapie du cancer et du sida.

It grows in many parts of the world and is mainly present in tropical regions. It is known for its tolerance to unfavourable abiotic conditions as well as its medicinal therapeutic virtues such as the pharmacological activities of the phytochemical compounds founded in the extracts of the plant (flavonoids, alka loids and tanins). In the same way, the ricinus presents a very toxic compound: the ricine which, associated to monoclonal antibodies, is used in cancer and AIDS therapies.
The salinity effects on the germination and the growth of greenhouse grown castor bean (Ricinus communis L.) from three local provenances (Sidi Thabet, Grombalia and Kairouan) were studied. Plants were grown in sand-perlite mixture and irrigated with solution containing 0, 2, 5, and 10 g/l NaCl. The effect of salt stress on germination was weakly pronounced in the case of castor bean for the three provenances compared to control. Moreover, salt stress induced significant differences on plant growth during the experimental period. After 80 stress days, decreases in plant height were observed. 10 g/l NaCl has an intense depressive effect on seedling stage. The seedlings have not completed their development and this is noticed for all provenances. 5 g/l NaCl has also an intense depressive effect only for Grombalia. With regards to the mineral nutrition, hypocotyls are more concentrated in Na + and Cl -than the other organs. Thus, we observed a slight increase in K + concentration for 2 and 5 g/l NaCl compared to control, especially for Kairouan in stems. Based on the stability of the tolerance to salinity from germinative stage to seedlings stage, the provenance of Kai rouan was identified as the most tolerant and the provenance of Grombalia as the most sensitive to salt toxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
