Biological Effects of Peptide Powder from Crocodylus siamensis
摘要
Abstract
In the previous study.we had reported that peptide powder from Crocodylus siamensis was prepared using the enzymatic catalysis of trypsin. In this paper,the effects of this peptide powder on the scavenging ? OH,O2- ? .and DPPH.and its total reducing power were further investigated to reveal the antioxidation. Inhibitory effect on mushroom tyrosinase of the peptide powder was also studied. The results showed that the peptide powder had a strong antioxidant activity,with its half scavenging concentration to ? OH, O2- ? .and DPPH being 1. 2,2. Land 6. 5 mg/mL,respectively,and there was a positive correlation between the reducing power andits concentration. The peptide powder could strongly inhibit the biphenolase activity of mushroom tyrosinase, and the value of Icso was determined to be 6. 60 mg/mL. Our results indicate that peptide powder from C. Siamensis is a natural health product, and has some potential properties in anti-fatigue and anti-aging.关键词
