Physicochemical characteristics and immunoregulatory activities of polysaccharides from five cultivars of Chrysanthemi Flos

This study compared the physicochemical characteristics and immunomodulatory activities of chrysanthemums' polysaccharides (JPs) from five cultivars. Significant differences were found in the molecular weights, the ratios of monosaccharide compositions, and morphological properties. Polysaccharides of Gongju (GJP) had the lowest molecular weight populations and polysaccharides of Boju (BJP) had the highest.
