Figures & data
Figure 1. Chemical structures of compounds 1–6 isolated from Syringa patula.
Figure 2. Cytotoxicity of tested compounds against Hep-G2 cells after treatment for 24 h with different concentrations of β-amyrin acetate (circles), syringaresinol (squares), and oleoside 11-methyl ester (triangles), as estimated by MTT assay. Results are presented as a percentage compared to control cells treated with solvent (mean of four readings ± SD).
Figure 3. Proliferation index of RAW 264.7 cells after treatment with different concentrations of β-amyrin acetate (circles), syringaresinol (squares), and oleoside 11-methyl ester (triangles), as estimated by MTT assay. As described in “Materials and methods”, the proliferation index was calculated relative to control.
Figure 4. Evaluation of nitrite production (nmol nitrite/mg cellular protein, mean ± SD) by RAW 264.7 cells stimulated for 20 h by LPS (1 μg/mL) alone or in combination with 20 μg/mL of the different compounds.
