Abstract:

Study on antioxidant and whitening efficacy of tussah fibroin peptides was conducted. The results show that the IC50 of DPPH free radical scavenging rate of NO.1 (molecular weight 2 000-5 000 Da) and NO.2 (molecular weight<2 000 Da) samples are 1.41 and 3.84 mg/mL, respectively, and the IC50 of hydroxyl free radical scavenging rate are 0.085 and 0.091 mg/mL, respectively. The total reducing power level increases with the sample dosage. The addition of tussah fibroin peptides have a protective effect on the UV-damaged mouse fibroblasts through increasing the activity of SOD and the content of GSH, and decreasing the content of MDA. In the evaluation of whitening efficacy, the IC50 of No.1 and No.2 samples of tyrosinase inhibition effect rate are 3.65 and 5.84 mg/mL, respectively, which can inhibit melanin synthesis and tyrosinase activity in mouse melanoma cells. In conclusion, tussah silk fibroin peptides have antioxidant and whitening activity, and the NO.1 sample with larger molecular weight is better than the NO.2 sample with smaller molecular weight.

Key words: tussah fibroin peptides, anti-oxidation, resistance to UV oxidative damage
