Polysaccharides are possibly involved in the pharmacological effects of Viscum album (mistletoe) extracts, which are used in cancer therapy. Therefore the water-soluble polysaccharides of the fresh plant and the fermented proprietary preparation Iscador® were isolated and characterized inter alia by methylation analysis, partial hydrolysis and C-13-NMR spectroscopy. The main polysaccharide of the green parts of Viscum is a highly esterified galacturonan whereas in Viscum ‘berries’ a complex arabinogalactan is predominant. Both types of these constituents were found in Iscador but with definite changes in molecular weight and structure. An interaction between the arabinogalactan and the galactose-specific lectin (ML I) in Viscum could be demonstrated. In three immunological tests (granulocyte, chemiluminescence, carbon clearance test) the polysaccharides failed to increase phagocytic activity of granulocytes and macrophages.
