From the water or alcaline-water extracts of Echinacea purpurea (L.) Moench and -angustifolia DC., Eupatorium cannabinum L. and -perfoliatum L., Chamomilla recutita (L.) (Rauscher), Calendula officinalis L., Baptisia tinctoria (L.) R.B., Achyrocline satureoides DC., Arnica montana L., Sabal serrulata Roem et Schult. and Eleutherococcus senticosus Maxim. polysaccharide fractions with molecular weights in the range of 25 000 to 500 000 and higher have been isolated, which, according to the granulocytes- and carbon clearance tests, showed significant immunostimulating activities. The isolated compounds belong to the group of water-soluble, acidic heteroglycanes. The linkages in the different polysaccharides do not represent a uniform structure type.
