Eckol is a phlorotannin isolated from brown algae in the family Lessoniaceae such as species in the genus Ecklonia[1] such as E. cava[2] or E. kurome[3] or in the genus Eisenia such as Eisenia bicyclis.[4]
The molecule possesses a dibenzo-p-dioxin skeleton and a phloroglucinol component. The molecule can also be viewed as a phloroglucinol trimer.[5]
It exhibits an antiplasmin inhibitory effect[3] and a radioprotective effect in a mouse model.[1][6] It also exhibits an in vitro cytoprotective effect against oxidative stress in Chinese hamster lung fibroblasts.[2] It also shows antithrombotic and profibrinolytic activities.[4]
