Abstract:

The aim of this study was to investigate the anti-aging and soothing effects of Lanzhou lily flower peptides (LLFPs) generated via enzymatic hydrolysis and microbial fermentation. Comprehensive methodologies including LC-MS/MS analysis, fluorescent probes, ELISA, qRT-PCR, an acetic acid-induced zebrafish model, and human clinical trials were employed to evaluate the related biomarkers across multiple dimensions, alongside chemical component identification. Results demonstrate that LLFPs contain 535 short-chain peptides, with 76.09% exhibiting molecular weights <1 000 Da. The peptides significantly reduce UVB-induced MMP-1 and ROS expression in keratinocytes, promote dermal fibroblast proliferation and collagen secretion, modulate circadian clock genes (CLOCK, BMAL1), alleviate UVB-induced photo-oxidative stress in keratinocytes, and decrease total movement distance in acetic acid-stimulated zebrafish. Clinical trials further validate the anti-aging and soothing efficacy of LLFPs in human subjects. Through integrated in vitro and in vivo verification, this research reveals the dual anti-aging and soothing efficacy of LLFPs, providing a scientific foundation for their application in cosmetic formulations.
