Abstract:

The aim was to study the transdermal penetration characteristics of tea polyphenols and explore the protective effect of tea polyphenols on UVA-induced oxidative damage in human skin fibroblasts (HSF). Using the Franz diffusion cell with rat skin as a barrier, a well-performed detection method was established to detect the percutaneous penetration indexes of catechin, epicatechin, epicatechin gallate and epigallocatechin gallate in tea polyphenols by high performance liquid chromatography (HPLC). The model of HSF damaged by UVA was established to explore the effect of tea polyphenols on the content of reactive oxygen species (ROS), the level of malondialdehyde (MDA), the enzymatic activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in cells. The results show that the detection method has good specificity, precision and average recovery. The transdermal permeability of catechin and epicatechin increase gradually with the increase of time, and the infiltration rate of epicatechin is greater than that of catechin. However, the transdermal permeability of epicatechin galate and epigallocatechin galate can not be detected in the 24 h experiment, but the two substances remain more in the skin, indicating that the four substances in tea polyphenols can be applied to the skin well. Besides, tea polyphenols have significant protective effect on UVA-induced oxidative damage in HSF by reducing the content of ROS and the level of MDA, increasing the enzymatic activity of SOD and GSH-Px.
