Anti-tumor effect of plant polysaccharides

Current studies believe that plant polysaccharides are mainly used to enhance the immune function of the body to achieve the purpose of killing tumor cells, that is, the anti-cancer effect passes through the host-mediated effect to enhance the body's non-specific and specific immune effects, rather than directly killing tumor cells. It is also related to the influence of polysaccharides on cell biochemical metabolism, inhibition of tumor cell cycle and inhibition of SOD activity in tumor tissues. Lycium barbarum polysaccharide can enhance the function of the anti-cancer immune surveillance system; kelp polysaccharide has a significant inhibitory effect on tumor-bearing H22 mice, and its tumor inhibition rate is as high as 43.5%; Grifola frondosa polysaccharide can significantly inhibit tumor growth and enhance mice Immune Function. Other polysaccharides such as spirulina polysaccharide, tremella polysaccharide, ginseng polysaccharide, lentinan, polyporus polysaccharide, wolfberry polysaccharide, astragalus polysaccharide, Ganoderma lucidum polysaccharide, bamboo leaf polysaccharide, Flammulina velutipes polysaccharide, Cordyceps polysaccharide have anti-tumor effects.
