AI Technical Summary

Technical Problem

Existing antiviral drugs for influenza have significant side effects and are prone to drug resistance. Furthermore, there is limited research on the application of Panax notoginseng polysaccharide in antiviral activity, which limits its efficacy.

Method used

Polysaccharide extracts from *Panax notoginseng* were purified by water extraction and alcohol precipitation, ion exchange chromatography, and gel size exclusion chromatography to obtain polysaccharides with molecular weights between 50.0 kDa and 100.0 kDa. These polysaccharides are used to prepare antiviral drugs and lung protectants targeting the H1N1 subtype of influenza A virus.

Benefits of technology

The polysaccharide of *Panax notoginseng* significantly inhibits the activity of influenza virus, prolongs the survival time of experimental animals, and improves the pathological damage to the lungs caused by influenza virus, thus expanding the scope of efficacy of *Panax notoginseng* polysaccharide and providing a new direction for the prevention and treatment of influenza virus.
