Abstract: In this study, papain, flavourzyme, alcalase and trypsin were separately used to hydrolyze Hericium erinaceus proteins, yielding peptides designated as HEPH-P, HEPH-F, HEPH-A, and HEPH-T, respectively. Their antioxidant, anti-inflammatory activity, and antitumor activities were evaluated. The results showed that HEPH-P had good 2,2-di(4-tert-octylphenyl)-1-picrylhydrazyl (DPPH) radical and hydroxyl radical-scavenging activities, with scavenging percentages of (53.01 ± 0.27)% and (55.73 ± 1.52)%, respectively. HEPH-A showed anti-inflammatory activity by effectively controlling the release of NO and interleukin (IL)-6 and promoting the secretion of IL-10 in lipopolysaccharide (LPS)-induced RAW264.7 cells. HEPH-P resulted in the rupturing of the cell membrane, triggered apoptosis and ultimately inhibited the proliferation of liver cancer cells. This study can provide a theoretical basis for the development and application of functionally active peptides from Hericium erinaceus proteins.
