| Abstract: | Lectin activity in immature pods from 30 strains of winged bean was investigated. Most of the lectin activity occurred in green shells and a small portion in immature seeds. Hemagglutinating activity of green shells was classified into four groups, according to the agglutination of trypsinized human type A, B, and O erythrocytes. Extracts from green shells of four representative strains which showed different hemagglutination patterns gave different elution profiles of lectin activity from ion exchange columns. Four types of lectin activity with different blood group specificities were apparently found in green shells. |
