摘要： This invention belongs to the technical field of plant extract separation, and specifically relates to a pollen polysaccharide 1-4 and its separation method and application. This invention extracts, separates and purifies the polysaccharide from oilseed rape pollen to obtain pollen polysaccharide 1-4, which have been tested to be effective in the direction of plant growth-promoting and stress resistance. At the same time, the invention also finds that the pollen polysaccharide active moiety Fr, the pollen polysaccharide active moiety Fr-1 and the pollen polysaccharide active moiety Fr-1-5 of the crude isolated component of rape pollen also have plant growth-promoting and stress-resistant effects.
