Eckol is a phlorotannin isolated from brown algae in the family Lessoniaceae such as species in the genus Ecklonia such as E. cava or E. kurome or in the genus Eisenia such as Eisenia bicyclis.

The molecule possesses a dibenzo-p-dioxin skeleton and a phloroglucinol component. The molecule can also be viewed as a phloroglucinol trimer.

It exhibits an anti-plasmin inhibitory effect and a radioprotective effect in mice. It also exhibits a cytoprotective effect against oxidative stress in Chinese hamster lung fibroblasts. It also shows antithrombotic and profibrinolytic activities.
