Ecklonia cava

Ecklonia cava is an edible marine brown alga species found in the ocean off Japan and Korea.

It is used as an herbal remedy in the form of an extract called Seanol, a polyphenolic extract, and Ventol, a phlorotannin-rich natural agent.[1]

Phlorotannins, such as fucodiphlorethol G,[2] 7-phloro eckol, 6,6'-bieckol,[3] eckol, 8,8'-bieckol, 8,4"'-dieckol and phlorofucofuroeckol A can be isolated from Ecklonia cava.[4]

Other components are common sterol derivatives (fucosterol, ergosterol and cholesterol).[3]
