  Ecklonia stolonifera (Japanese: ツルアラメ, turuarame) is a brown alga species in the genus Ecklonia found in the Sea of Japan. It is an edible species traditionally eaten in Japan.
  
  ## Chemistry
  
  ### Phlorotannins
  
  Ecklonia stolonifera contains the phlorotannins phlorofucofuroeckol A, eckol, dieckol, dioxinodehydroeckol (eckstolonol), 2-phloroeckol, phlorofucofuroeckol B, 6,6'-bieckol, triphlorethol-A, phloroglucinol and 7-phloroeckol.
  
  Those phlorotannins are responsible for the potent pharmacological effects associated with this seaweed. These molecules show a hepatoprotective activity.
  
  ### Oxylipins
  
  The oxylipins ecklonialactones A, B, C, D, E and F and fucosterol can also be isolated from the species.
