Effects of Antitumor Polysaccharides from Forsythia Corea on the lumune Function (I)

  • Published : 1985.03.01


Polysaccharide fractions were prepared from Forsythia Corea by several different extraction schedules. The fractions obtained were designated as ForCo A, ForCo B and ForCo C respectively. ForCo C was further purified through Sephadex G 200 column chromatography and obtianed two subfractions (Coreana A, Coreana B). ForCo showed marked antitumor activity against sarooma 180 and its activity was dose-dependent. Coreana A, purified from ForCo C, showed somewhat higher antitumor activity. ForCo C increased the number of circulating leucocytes and peritoneal exudate cells, but didn't show any significant effects on the phagocytic activity and total serum protein level. Chemical analysis showed that ForCo C was composed of glucose, galactose, xylose and arabinose. A close relationship between antitumor activities and polysaccharide contents waw observed. These results indicate strongly that antitumor active principle of Forsythia Corea is polysaccharide.
