| contents | This study employed neutral PBS buffer combined with ammonium sulfate fractionation to isolate peptide-active fractions (PD-30, PD-50, PD-80) from Cuminum cyminum L.seeds (cumin) and systematically evaluated their antimicrobial, antioxidant, hypoglycemic, and anticancer activities. The results demonstrated that the PD-80 fraction exhibited potent antifungal activity against Candida albicans (inhibition zone diameter: 12.5 mm) and significant antioxidant capacity, with DPPH and ABTS radical scavenging rates of 72.4% and 78.9%. The PD-50 fraction showed the strongest antibacterial effect against Escherichia coli (inhibition zone diameter: 11.7mm), while PD-30 displayed the highest inhibitory activity against PTP1B (IC50=18.39 ug/mL), indicating its potential for hypoglycemic applications. Through mass spectrometry and database alignment, 414 peptides were identified for the first time in cumin-derived PBS extracts, including 18 structurally novel monomers comprising 11 antimicrobial peptides, 7 anticancer peptides, and 6 hypoglycemic peptides. Notably, peptide CK12 shares sequence homology (59% similarity) with the HIV fusion inhibitor T20, suggesting potential antiviral activity. This study elucidates the multifunctionality and structural basis of cumin peptides, providing a theoretical foundation for their application in natural pharmaceuticals and functional foods. Future research will focus on chemical modification and in vivo validation to advance their utilization in precision medicine and the modernization of traditional Chinese medicine. |
