説明Echinacoside is a phenylethanoid glycoside that has been found in Echinacea and has diverse biological activities. It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) radicals (EC50 = 6.6 μM in a cell-free assay). Echinacoside (10 μg/ml) inhibits hydrogen peroxide-induced production of reactive oxygen species (ROS) and apoptosis in PC12 cells. It reduces increases in plasma alanine aminotransferase (ALT), TNF-α, IL-1β, IL-16, and IL-10 levels and hepatocyte apoptosis induced by LPS/D-galactosamine in a mouse model of acute liver injury when administered at a dose of 60 mg/kg. Echinacoside (20 mg/kg per day for 15 days) prevents loss of dopaminergic neurons in the substantia nigra pars compacta and decreases in striatal dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) levels in a mouse model of MPTP-induced Parkinson''s disease. It also improves motor performance in the rotarod test in the same model.

使用Echinacoside Ethanolate is a caffeic acid glycoside, known for its neuroprotective, antiinflammatory and anti-oxidative activities. Also an anti[proliferative towards hypoxia influenced pulmonary artery smooth muscle cells.
