Two new acidic polysaccharides, F4 and F5, were isolated from the flowers of Chrysanthemum morifolium. Monosaccharide analysis indicated that F4 contained arabinose, galactose and galacturonic acid units in a molar ratio of 1.0:2.3:6.8 and F5 contained arabinose, rhamnose galactose and galacturonic acid units in a molar ratio of 1.0:3.2:1.0:4.3. The results of methylation analysis, partial acid hydrolysis and NMR spectral analysis indicated that F4 had a homogalacturonan main chain with arabinogalactan side chain linked to 3 position of (1 --> 3,4)-linked galacturonan and F5 had a rhamnogalacturonan main chain with arabinogalactan side chain linked to 3 position of (1 --> 3,4)-linked galacturonan or 4 position of (1 --> 2,4)-linked rhamnose. Biological tests revealed that F4 and F5 could simulate the mitogen induced T and B lymphocyte proliferation in vitro.
