title: The occurrence of materials cross-reacting with anti-A and -B agglutinins in fruit or seed extracts of higher plants.
abstract: Fourteen species of higher plants were found to contain materials in their fruit or seed extracts which were heat stable, inhibitory for and capable of absorbing anti-H, -A and -B agglutinins and also lectins. The majority of species exhibiting a high grade of such cross-reactivity belonged to two genera, Viburnum of the Caprifoliaceae and Acer of the Aceraceae. Gel diffusion patterns indicated, however, that the A- and B-like activities of the Viburnum fruits were somewhat distinct serologically from blood group A and B substances of human origin.
