From the water or alcaline-water extracts of Echinacea purpurea (L.) Moench. and -angustifolia DC., Eupatorium cannabium L. and -perfoliatum L., Chamomilla recutita L. Rauscher, Calendula officinalis L., Baptisia tinctoria (L.) R. B., Achyrocline satureioides DC., Arnica montana L., Sabal serrulata Roem. et Schult., and Eleutherococcus (Acanthopanax) 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 watersoluble, acidic branched-chain heteroglycans. Their immunostimulating activity is compared and discussed with respect to other polysaccharides of biological activity.
