The present work reported the extraction, purification and characterization of an inulin fructan from Codonopsis pilosula (CPW1) and its application in stabilization of selenium nanoparticles (SeNPs). The morphology, stability, and stabilization mechanism of CPW1 stabilized SeNPs (CPW1-Se) were explored, and the results showed that the SeNPs were amorphous state, with size of 54–79 nm, and kept stable within 15 days due to the interaction between SeNPs and the hydroxyl groups on the surface of CPW1. Moreover, the effects on proliferation and apoptosis of CPW1-Se to both normal cells (293T) and liver cancer cells (Huh-7 and HepG2) were evaluated systematically by using the CCK8 assay, plate clone formation assay, flow cytometry and western blot. The results indicated that CPW1-Se possessed selective anti-hepatoma activities without side effects on normal cells, which exhibited strong potential application in liver cancer treatments.
