Figures & data
Figure 1. Inhibitory effects on NO production and cytotoxicity of total extract and each fraction (A and B), and compounds 1−13 (C and D) isolated from J. rigida leaves and twigs in LPS-stimulated RAW264.7 cells. The RAW264.7 cells were pretreated with each sample to be tested for 1 h before exposure to LPS for 24 h. The concentration of nitrite in culture medium was measured by Griess reaction and sodium nitrite was used as a standard. The values shown are mean ± SD of three independent experiments. The results differ significantly from LPS-only treated; *p < 0.01, **p < 0.001.
