Ecklonia kurome

Ecklonia kurome (黑布 (kurome), 鹅掌菜) is a brown alga species in the genus Ecklonia found in the Sea of Japan.

The phlorotannins eckol, phlorofucofuroeckol A and 8,8'-bieckol can be found in Ecklonia kurome.

An oligosaccharide extract from Ecklonia kurome called GV-971 is approved in China for the treatment of Alzheimer's disease, but the evidence is highly dubious.
