Decursinol is a coumarin that has been found in Angelica gigas and has diverse biological activities.1,2,3,4 It inhibits glutamate-induced neuronal cell death in primary rat mixed cortical cells when used at concentrations of 0.1, 1, and 10 ?M. Dietary administration of decursinol (0.004%) reduces decreases in spontaneous alternation induced by amyloid-β (1-42) in the Y-maze, indicating prevention of memory deficits, in mice.2 Decursinol (10 mg/kg) reduces tumor metastasis in a CT26 colorectal cancer mouse xenograft model.3 It inhibits acetic acid-induced writhing in mice when administered at a dose of 50 mg/kg.4
