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.[1]

Chemistry

[edit]

Phlorotannins

[edit]

Ecklonia stolonifera contains the phlorotannins phlorofucofuroeckol A,[2] eckol, dieckol,[3] dioxinodehydroeckol[4] (eckstolonol),[5] 2-phloroeckol, phlorofucofuroeckol B, 6,6'-bieckol,[6] triphlorethol-A,[7] phloroglucinol and 7-phloroeckol.[8]

Those phlorotannins are responsible for the potent pharmacological effects associated with this seaweed.[9] These molecules show a hepatoprotective activity.[6][10]

Oxylipins

[edit]

The oxylipins ecklonialactones A, B,[11] C, D, E and F[12] and fucosterol[7] can also be isolated from the species.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
