Comparison of Inhibitory Effects of Safflower Decoction and Safflower Injection on Protein and mRNA Expressions of iNOS and IL-1β in LPS-Activated RAW264.7 Cells

Figure 3

(a) The ORAC values of the samples and HSYA. Sample 1: the safflower decoction; sample 5: the safflower injection. Values are expressed as error (). versus sample 5. Curcumin was the positive control. ORAC: oxygen radical absorbance capacity; HSYA: Hydroxysafflor yellow A. (b) The IC50 values for DPPH scavenging of the samples and HSYA. Sample 1: the safflower decoction; sample 5: the safflower injection. Values are expressed as error of the mean (). versus sample 5. Curcumin was the positive control. DPPH: 1,1-diphenyl-2-trinitrophenylhydrazine; IC50: half inhibitory concentration; HSYA: Hydroxysafflor yellow A.
