Abstract:

In this study, lyophilized samples of collagen peptides were prepared from enzymatic hydrolysis of Navodon
septentionalis bone. Our analysis results showed that the peptides had maximum absorption at 220 nm and consisted of 3%
hydroxyproline. At 60 mg/mL, the peptides had antioxidant activity equivalent to that of GSH, and at 25 mg/mL, scavenged
95.98% of hydroxyl free radical and 97.36% of 1,1-diphenyl-2-picryhydrazyl (DPPH) free radical.

Key words: Navodon septentionalis bone, collagen polypeptide, amino analysis, MALDI-TOF, antioxidant activity
