Abstract

Ultraviolet B (UVB) exposure can contribute to photoaging of skin. is rich in ursolic acid (UA), which is beneficial to the prevention of photoaging. Because UA is hardly soluble in water, the extract (COE) was obtained using water as the antisolvent to separate the components containing UA from the crude extract of . The effect of COE on UVB damage was assessed using . The results showed that COE could increase the lifespan and enhance the antioxidant enzyme activity of exposed to UVB while decreasing the reactive oxygen species (ROS) level. At the same time, COE upregulated the expression of antioxidant-related genes and promoted the migration of SKN-1 to the nucleus. Moreover, COE inhibited the expression of the downstream gene and the extension of the lifespan in mutants exposed to UVB, indicating that SKN-1 was required for COE to function. Our findings indicate that COE mainly ameliorates the oxidative stress caused by UVB in via the SKN-1/Nrf2 pathway.
