Abstract

The invention discloses a polysaccharide SM‑0.2M, which is separated from raspberry polysaccharides, and its specific sugar chain structure is identified. It is verified by experiments that the polysaccharide SM‑0.2M can promote the proliferation of macrophages, and can promote macrophages The cells release NO, up-regulate the expression of TNF-α and IL-6, and then enhance the phagocytosis of macrophages, improve immunity, and help macrophages play an anti-tumor effect, which can be used to prepare related products, and to further prove The structure-activity relationship of raspberry polysaccharides and the development of polysaccharide antitumor drugs and immune adjuvants provide reference.

Description

technical field

[0001] The invention belongs to the technical field of natural products, and in particular relates to polysaccharide SM-0.2M in raspberry polysaccharide and its preparation method and application. Background technique

[0002] Plant polysaccharides, also known as plant polysaccharides, are polysaccharides with a degree of polymerization of more than 10 produced by plant cell metabolism. Important biological macromolecules in living organisms are one of the basic substances to maintain the normal operation of life activities.

[0003] At the same time, plant polysaccharides are recognized as natural macromolecules with various biological activities, and most plant polysaccharides have significant immunomodulatory and antitumor activities in vivo. They can not only directly affect the functions of various immune cells such as macrophages, T lymphocytes, B lymphocytes, and natural killer cells, but also regulate the production of related cytokines and complemen...
