Popis: Skin aging is associated with increased reactive oxygen species (ROS) produced by human cells. These radicals are the main causes of skin aging, and skin cells have developed antioxidant enzymes for protection against ROS-induced damage. Antioxidants play critical roles to prevent ROS-induced aging symptoms. In this study, the antioxidant properties of Pourthiaea villosa (Thunb.) Decne. extract (PVDE) were studied. Human dermal fibroblast (HDF) cells were treated with PVDE to evaluate its antioxidant and antiaging activities and to investigate the underlying mechanisms. The identified compounds were polyols, and phenolic and flavonoid compounds from PVDE by UHPLC-LTQ-IT-MS/MS. PVDE exhibited significant antioxidant effects, as evaluated with reducing power, and ABTS and DPPH radical scavenging activity. Furthermore, PVDE treatment significantly increased antioxidant enzyme expressions and effectively blocked H2O2-induced matrix metalloproteinase activity through MAPK signaling pathways in HDFs. Therefore, these results showed that PVDE affords an advantage of being a functional natural material with antioxidant and antiaging effects for the skin.
