Assessment of lectinic activity potentials in extracts of some tropical Euphorbiaceace

Lectins bind a variety of cells having cell surface glycoprotein or glycolipid, such as erythrocytes, leukemic cells, yeast and several types bacteria. Several specificity groups have been identified mannose, galactose, N-acetyl glucoseamine, galactoseamine, L-fucose neuraminic acid. The presence two more binding sites for each Lectin molecule allows the agglutination many type. Sixteen (16) species some tropical Euphorbiaceae plants were assessed Lectins. leaves Acalypha torta, wiskesiana, hispida, Codiaeum variegatum, Euphorbia milli, pulcherima, Jatropha curcas gossypifola; seeds Croton tiglium, Ricinus comminus Tetracarpidium conophorum; stem tirucalli tubers Manihot esculenta (Cassava, vitamin A variety), (cassava, NR 8082 TMX 419 4(2) 1425 variety) used sourcing A. C. E. tirucalli, J. curcas, gossypifola, R. T. conophorum agglutinated pooled washed human ABO in saline (direct haemagglutination) while hispida four varieties M. showed no reaction. pulcherima B only O only, hence could be rightly indicated by referring to them anti-B Ep anti-H Et respectively (where Ep=Euphorbia Et= tirucalli). However torta cross-reacted with differing strengths when standardized, that at titre 16 reacted specifically 128 cells. Based on this, these At Tc (Where At= Tc= conophorum). protein content crude extracts sixteen also assayed using Biuret assay method results revealed there are relation association between quantity patterns extracts. This research has therefore succeeded revealing Lectinic properties Euphorbiaceae.
