Figure 5: Effect of nine marker compounds from Xanthii fructus on lipopolysaccharide-stimulated interleukin-6 production in RAW 264.7 cells. Each bar represents the mean of three independent experiments (#P < 0.05 and ##P < 0.01 versus untreated control; **P < 0.01 versus lipopolysaccharide-treated cells). (a) Protocatechuic acid, (b) chlorogenic acid, (c) caffeic acid, (d) 1,4-dicaffeoylquinic acid, (e) 1,3-dicaffeoylquinic acid, (f ) ferulic acid, (g) 1,5-dicaffeoylquinic acid, (h) 3,5-dicaffeoylquinic acid, and (i) 4,5-dicaffeoylquinic acid
