The molecule is a member of the class of coumarins that is 7-methoxycoumarin in which the hydrogen at position 6 has been replaced by a 1-ethoxy-2,3-dihydroxy-3-methylbutyl group (the R,R stereoisomer). Originally isolated from the roots of Angelica pubescens, angelol J shows strong inhibitory effects on human platelet aggregation. It has a role as a platelet aggregation inhibitor and a plant metabolite. It is a member of coumarins, an aromatic ether and a diol.
