Extraction, purification, structural features, biological activities, modifications, and applications from Taraxacum mongolicum polysaccharides: A review.

Dandelion (Taraxacum mongolicum Hand.-Mazz), as a famous medicinal and edible plant, has the effects of clearing heat and detoxifying, diuresis, and resolving masses. Phytochemistry investigations revealed that T. mongolicum has various bioactive ingredients, mainly including flavonoids, sterols, polysaccharides, phenolic acids and volatile oils. There is growing evidence have shown that the polysaccharides from T. mongolicum (TMPs) are a class of representative pharmacologically bioactive macromolecules with a variety of biological activities both in vitro and in vivo, such as immunomodulatory, anti-inflammatory, anti-oxidant, anti-tumor, hepatoprotective, hypolipidemic and hypoglycemic, anti-bacterial, regulation of intestinal microbial, and anti-fatigue activities, etc. Additionally, the structural modification and potential applications of TMPs were also outlined. The present review aims to comprehensively and systematically collate the recent research progress on extraction and purification methods, structural characteristics, biological activities, mechanism of action, structural modification, and potential industry applications of TMPs to support their therapeutic potential and health care functions. Overall, the present review provides a theoretical overview for further development and utilization of TMPs in the fields of pharmaceutical and health food.
