Effect and mechanism of Tricholoma matsutake extract combined with bakuchiol and ergothioneine on UVB‐induced skin aging

Abstract Background Aging is a physiological phenomenon in the process of life, and skin aging has a significant impact on human appearance. Therefore, the search for methods to delay skin aging is of great significance for improving the quality of human life. Materials and Methods This study investigated the anti‐photoaging effect of Tricholoma matsutake (T) extract composition combined with bakuchiol (B) and ergothioneine (E), and explored its potential mechanism through transcriptome, metabolomics, and network pharmacology. Results 57 main chemical components are identified from the ethanol extract of T. matsutake (T), including D‐carnitine (24.55%), α,α‐trehalose (15.56%), DL malic acid (8.99%), D‐(−)‐quinic acid (7.46%), erucamide (7.04%) and so on. After TBE treatment, inflammation of the mice dorsal skin is significantly minimized. Hematoxylin and eosin (H&E) staining and toluidine blue staining reveal that TBE has an anti‐inflammatory effect on the back skin tissue of mice. Masson staining shows that TBE has a repair effect on mice dorsal skin tissue. In addition, the inflammatory factors (IL‐1β, IL‐6, TNF‐α) in the mice dorsal skin tissues are significantly reduced but collagen (COL‐1) is significantly increased. By cellular immunofluorescence assay, TBE is shown to promote PPAR‐α expression in cells. Transcriptomics, metabolomics, and network pharmacology have revealed that TBE can regulate exogenous stimuli and cancer‐related signaling pathways to prevent skin aging. Conclusion The results suggest that TBE can be a beneficial supplement to natural anti‐aging.
