The structure of the title compound [systematic name: (1R,4aS,7R,8S,E)‐8‐cinnamoxyloxy‐7‐isopropyl‐4a‐methyldecahydronaphthalene‐1‐carboxylic acid], C24H32O4, isolated from Verbesina turbacensis collected in Costa Rica, shows a eudesman sesquiterpene skeleton with normal values of bond lengths and angles. In the crystal structure, the hydroxy group is involved in the formation of intermolecular O—H...O hydrogen bonds, which link the molecules into zigzag chains extended along the [001] direction.
