Abstract:

A preparation process of tussah silk fibroin peptide liposomes with high encapsulation efficiency and suitable particle size was established by the reverse rotary evaporation method, and their anti-photodamage effect was evaluated in this study. The results show that the optimal encapsulation effect of tussah silk fibroin peptide liposomes is achieved by optimizing the single factor test to ascertain the preparation parameters of the mass ratio of cholesterol to lecithin of 1∶11, the aqueous phase volume of 3 mL, the pH of PBS solution of 8.0, the first ultrasound of 3 min, the second ultrasound of 5 min, and the emulsification temperature of 40 ℃. The tussah silk fibroin peptide liposomes are capable of ameliorating the photodamage to mouse embryonic fibroblasts by repairing collagen, enhancing anti-oxidation and exerting anti-inflammatory effects. Ultraviolet damage of zebrafish is alleviated by reducing reactive oxygen species (ROS) levels and repairing the tail fin. This study confirms the potential of tussah silk fibroin peptide liposomes in resisting skin photodamage, thereby rendering them suitable for application in skin care products.

Key words: tussah silk fibroin peptide, liposome, antioxidant, anti-inflammatory, photodamage repair
