In order to investigate antitumor activity of Alfalfa polysaccharides,crude Alfalfa polysaccharide were extracted by hot water and purified by DEAE-cellulose column chromatography,four ingredients S1,S2,S3,S4 were obtained.Crude polysaccharides S0 and S1,S2,S3,S4 were respectively injected to mice implanted Sarcoma 180 and Hepatoma 22 ascitic fluid tumor,the body weight change of mice and its life-span were also detected.The results showed that S1 and S2 could inhibit weight increase and strikingly prolonger the life-span of mice implanted Sarcoma 180 or Hepatoma 22 than those of control group mice.
