Abstract:

Saccharomyces cerevisiae was used to ferment Lycium ruthenicum to obtain fermented Lycium ruthenicum broth (FLRB). The components of FLRB were detected and the safety and the anti-aging effect were evaluated. These results would provide theoretical basis for its application in the field of cosmetics. Firstly, the free radical scavenging ability of FLRB was tested at the biochemical level, and then the anti-aging effects were evaluated at cellular level, including collagen formation, expression of collagenase, and activities of antioxidant enzymes in human fibroblasts. Finally, the eye irritation and skin safety of the FLRB were tested by chick embryo chorioallantoic membrane and human patch experiments. Results show that the FLRB is rich in polysaccharides and proteins, and is less in flavonoids, polyphenols and proanthocyanidins. The FLRB has significant ability to scavenge DPPH free radicals and ABTS+free radicals, with IC50 values of 8.15% and 1.08%, respectively. The FLRB of 5% volume fraction can promote collagen production to a content being 137.84% (p<0.01) of the control group and can inhibit collagenase production to a content being 70.41% (p<0.01) of the control group. The activities of GSH-Px and CAT and the total antioxidant capacity are significantly (p<0.01) improved and reactive oxygen species is significantly (p<0.01) inhibited by the FLRB of 1% volume fraction. Chick embryo chorioallantoic membrane experiment and human patch test show that the FLRB is safe to human eyes and skin.
