Sementes de Parkia platycephala Benth.possuem uma lectina que é melhor extraída a pH 4,0 e pode ser isolada por cromatografia de afinidade em coluna de Sephadex G-50. A lectina aglutina eritrócitos de coelho mas não aglutina hemácias humanas (A, B e O), de boi, de carneiro ou de galinha. D-glicose, D-manose, D-frutose e derivados mostraram ser açúcares inibidores da atividade hemaglutinante, sendo que alfa-metil-glicosídeo e alfa-metil-manosídeo foram os mais potentes inibidores entre os açúcares testados. Seeds of Parkia platycephala Benth. have a lectin which is best extracted at pH 4,0 and partially purified using a Sephadex G-50 column as an affinity adsorbent. The lectin .agglutinates rabbit erythrocytes but not those of cow, sheep, chicken or human D-glucose, D-mannose, D-fructose and derivatives act as inhibitors of the lectin with o-methyl-glucopyranoside and O-methyl-mannopyranoside being the most potent ones
