Antiskin Inflammatory Activity of Black Ginger (Kaempferia parviflora) through Antioxidative Activity

Figure 6

Antioxidative effect of Kaempferia parviflora extract (KPE) and the involvement of oxidative stress in sUV-induced inflammatory mechanisms. The antioxidative effect of KPE was measured using ABTS (a), DPPH (b), and ORAC (c) assay. (d) N-acetyl-L-cysteine (NAC) suppressed sUV-induced COX-2 expression (d) and MAPK phosphorylation (e). NAC was treated to the cells prior to 1 h of sUV irradiation. Each protein amount was measured using Western blot analysis with specific primary antibodies. Data are representative of 3 independent experiments that gave similar results. The asterisks () indicate the significant difference (of ) compared to the untreated control.
