Panax notoginseng is a traditional Chinese medicine containing various constituents, including the saponins, polysaccharides, polyacetylenes, amino acids, etc. It has beneficial functions, such as the anti-inflammatory, antitumor, hepatoprotective, and anti-aging effects. Among these, P. notoginseng polysaccharides (PNPs) have been exploited because of their extensive pharmacological effects, being ranked as one of the current research hotspots, especially for the functional foods and medical practice. In this review, the literature related to PNPs in the past 20 years was surveyed and analyzed using both the China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) databases. The visualization diagram shows that current studies on PNPs mainly focus on the antioxidant and immunomodulatory activities and structural characterization. In addition, the extraction, separation, purification, chemical analysis, structural characteristics, bioactivities, and applications of PNPs are outlined, in detail, aimed to provide valuable information for the further study, development, and utilization regarding PNPs.
