Their potential correlations were analyzed by Pearson’s correlation analysis. Then, the oxidative stress model of H2O2-induced MSFs was used to evaluate the effects of different pnFE on MSF viability, reactive oxygen species (ROS), malondialdehyde (MDA), and the activities of catalase (CAT), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) to explore their protective effects on MSFs subjected to H2O2-induced cellular oxidative damage. Finally, their safety and stability were evaluated by using the red blood cell (RBC) test and hen’s egg test-chorioallantoic membrane (HET-CAM) assay, and changes in pH and content of soluble solids, respectively.Results: Compared with pnWE, pnFE has more active substances and stronger antioxidant capacity. In addition, pnFE has a protective effect on H2O2-induced oxidative stress in MSFs with appropriate safety and stability.Conclusion: PnFE has broad application prospects in the field of cosmetics.Keywords: Panax notoginseng, Saccharomyces cerevisiae, fermentation, oxidative stress, fibroblast cells, cosmetic ingredients |
