A flavonoid glycoside; scavenges DPPH radicals (IC50 = 0.35 UG/ml); reverses hydrogen peroxide-induced decreases in GSH levels and GPX and SOD activity in HL-7702 cells from 1-100 UG/ml; prevents palmitic acid-induced increases in protein levels of TLR4, MyD88, caspase-1, and IL-1β levels in HUVECs at 1 and 10 µM; decreases serum ALT, AST, TNF-α and IL-1 levels, as well as reduces liver inflammatory cell infiltration and hepatocyte necrosis in a mouse model of immunological liver injury induced by BCG vaccine and LPS
