Figure 4.

Biochemical assay kits were used to determine content of ALT, AST, MDA, and SOD. GAS protected the cells against H₂O₂-induced lipid peroxidation in HepG2 cells and reduced H₂O₂-induced reactive protein production. ALT, AST, and MDA content and SOD activity were measured in HepG2 cells. (a) The MDA level in HepG2 cells; (b) the SOD activity in HepG2 cells; (c) the content of AST; (d) the content of ALT. Error bars represent SD (n = 6). Experiments were performed at least three times. The annotation ## indicates a p value < 0.01 versus natural group. The annotation ∗∗ indicates a p value < 0.01 versus H₂O₂ group.
