Blood group specific plant agglutinins (phytoagglutinins) have already been known in
some foreign countries, but only a few studies on blood group specific phytoagglutinins
native to Korea have been presented.
Authors carried out agglutination and adsorption reaction of Dolichos lablab var.
dendalensis Nakai (DLVDN) and Glycine Max. merrill (GMM) native to Korea with A,
B, O, & AB human erythrocyres, studied their agglutinating inhibition reaction with
saliva and various sugars, and observed their test stability with the following results:
1) Saline extract of DLVDN was found contain anti-A (H) specific aggluttin, and the
heat stability of these agglutinins showed that the agglutinin treated at 1℃∼80℃ for 30
min. brought positive reaction but the aggultinin treated at 85℃ for 30min. produced a
negative reaction; and the agglutinating reaction was no inhibited by sugars such as
L-arabinose, D-xylose, D-mannose, dextrose, lactose and D-galactose.
2) Saline extract of GMM was found to contain anti-O (H) specific agglutinin and the
agglutinating reaction was inhibited by some sugars such as lactose and L-arabinose.
