Advances in the Extraction, Purification, Structural Characteristics and Biological Activities of Polysaccharides: A Promising Medicinal and Edible Resource With Development Value.

Abstract in brief

• Recent research highlights the growing interest in natural polysaccharides, especially their potential in food, medicine, and cosmetics, due to their health benefits such as anti-tumor, anti-inflammatory, and cardiovascular protection, primarily derived from lignans, flavonoids, and coumarins.
• The polysaccharides extracted from the root and rhizome of a medicinal plant (ESPS) have shown promising biological activities, but current studies mostly focus on small molecules; there is a lack of comprehensive information on their types and structural characteristics.
• The review discusses the progress in extracting, characterizing, and understanding the biological functions of ESPS, emphasizing the need for efficient extraction methods, resource utilization, and standardized quality control to support their further development and application.]
