L\'activite hemagglutinante des lectines est testee sur les graines de trois especes de courges (Cucurbitaceae) Citrullus lanatus (CL), Citrullus sp. (Csp), Cucumeropsis edulis (CE) de consommation courante en Cote d\'Ivoire (Afrique de l\'Ouest) et comparee a celle des graines de haricot Phaseolus vulgaris (PV). Les extraits de toutes les graines de courges montrent une activite hemagglutinante faible (4 a 128) par rapport a celledes graines de haricot (512 a 1024).Les hematies de lapin sont les plus reactives vis-a-vis des extraits bruts des graines de courges et de haricot. En plus, le traitement trypsique augmente la reactivite de ces memes hematies. La fraction proteique F5, obtenue par precipitation au sulfate d\'ammonium a 95% de saturation, de l\'extrait brut de Csppresente l\'activite hemagglutinante la plus elevee (512). Le traitement thermique a 100°C pendant 15 minutes reduit significativement l\'activite hemagglutinante des lectines desextraits bruts des graines de courges et de haricot ; le meme traitement applique pendant 30 minutes abouti a une inactivation totale des lectines de toutes ces graines. Lectin hemagglutinating activity has been assessed on the seeds of three species of Cucurbitaceae: Citrullus lanatus (CL), Citrullus sp. (Csp) and Cucumeropsis edulis (CE) of current consumption in Cote d\'Ivoire (West Africa), and compared with the seeds of haricot beans Phaseolus vulgaris (PV). The extracts of all the seeds of Cucurbitaceaeexhibit low levels of lectin activity (4 to 128), compared to those of beans (512 to 1024).The red blood cells of rabbit exhibit the highest reactivity both with Cucurbitaceae and beans seed crude extract. Moreover the treatment with trypsin enhances these same red blood cells reactivity. The highest levels of lectin activity have been measured on the protein fraction (F5) obtained by precipitation of the raw extract of Csp with the ammonium sulphate solution to 95% of saturation. The thermal treatment at 100 °C temperature for 15 minutes significantly reduce the levels of lectin activity of both seeds extracts of Cucurbitaceae and beans; the same treatment applied for 30 minutes results in total inactivation of the lectins of all these seeds.
