Neonauclea reticulata (Havil.) Merr Stimulates Skin Regeneration after UVB Exposure via ROS Scavenging and Modulation of the MAPK/MMPs/Collagen Pathway
Figure 2
Antioxidant effect of Neonauclea reticulata preparation on DPPH radical scavenging and AAPH-induced hemolysis (). (a) Effects of methanol and water extracts of Neonauclea reticulata (10–100 μg/mL) on DPPH radical scavenging. (b) Scavenging of hydrogen peroxide by Neonauclea reticulata. (c) Time course inhibition of water extract of Neonauclea reticulata (10–100 μg/mL) on AAPH-induced hemolysis. Neonauclea reticulata preparations exhibited DPPH radial scavenging activity at doses higher than 50 μg/mL. The IC50 of Neonauclea reticulata extract on DPPH radical scavenging was 10.2 μg/mL. The Neonauclea reticulata extract inhibited erythrocyte hemolysis in a dose-dependent manner (10–50 μg/mL). The IC50 of Neonauclea reticulata extract on AAPH-induced lysis of rat erythrocytes was 33.5 μg/mL.
