Seed samples of Sword bean (Canavalia gladiata) (Jacq, DC) were analysed for phytohaemagglutinating (lectin) activity. The lectins of raw seed samples exhibited lectin activity without any specificity against human “A”, “B”, and “O” erythrocytes. Among the different post harvest treatments almost complete reduction in phytohaemagglutinating activity was recordedwhen the seed samples were subject to autoclaving followed by dry heat treatment (roasting). Nonetheless, soaking in salt (NaCl) solution was found to be ineffective in reducing lectin activity.

Abstract


Seed samples of Sword bean (Canavalia gladiata) (Jacq, DC) were analysed for phytohaemagglutinating (lectin) activity. The lectins of raw seed samples exhibited lectin activity without any specificity against human “A”, “B”, and “O” erythrocytes. Among the different post harvest treatments almost complete reduction in phytohaemagglutinating activity was recordedwhen the seed samples were subject to autoclaving followed by dry heat treatment (roasting). Nonetheless, soaking in salt (NaCl) solution was found to be ineffective in reducing lectin activity.
