Abstract:

The lectin was extracted from seeds of Malania oleifera. It was precipitated with 20%, 40%, 60%, 80%, 100% saturation of ammonium sulfate and measured hemagglutination activity for chicken and rabbit erythrocytes, respectively. The result showed that the lectin lower to 80% ammonium sulfate precipitation had hemagglutination activities for chicken and rabbit erythrocytes, but not 100%. Up to 80% saturation of ammonium sulfate enabled to separate lectin from M. oleifera seeds completely. The results proved that the seeds of M. oleifera had agglutination. It was to lay the foundation for development and utilization of M. oleifera lectin.
