Area of Science:

  • Pharmacology and Traditional Medicine
  • Natural Product Chemistry
  • Biochemistry

Background:

  • Panax ginseng (P. ginseng) possesses a rich history of medicinal use.
  • While saponins were traditionally considered primary active compounds, recent research highlights the crucial role of ginseng polysaccharides.
  • Ginseng polysaccharides exhibit complex structural features and a wide range of biological activities.

Purpose of the Study:

  • To review the extraction, purification, structural characteristics, and biological activities of ginseng polysaccharides.
  • To explore the influence of different P. ginseng parts and growth conditions on polysaccharide properties.
  • To discuss the relationship between the structure and activity of ginseng polysaccharides.

Main Methods:

  • Literature review summarizing existing research on ginseng polysaccharides.
  • Analysis of studies detailing extraction and purification techniques.
  • Compilation of data on structural characterization and biological activity assays.

Main Results:

  • Ginseng polysaccharides from various parts (roots, flowers, stems, leaves, berries) and growth conditions (cultivated, mountain, wild) show diverse structures.
  • These polysaccharides demonstrate significant biological activities including immune regulation, anti-tumor, antioxidant, hypoglycemic, and anti-radiation effects.
  • A strong correlation exists between the structural characteristics of ginseng polysaccharides and their observed biological activities.

Conclusions:

  • Ginseng polysaccharides are vital contributors to the medicinal value of P. ginseng.
  • Understanding the structure-activity relationship is key to harnessing their therapeutic potential.
  • Further research into ginseng polysaccharides offers promising avenues for novel therapeutic applications.
