In-Depth Understanding of Ecklonia stolonifera Okamura: A Review of Its Bioactivities and Bioactive Compounds

Abstract

Ecklonia stolonifera Okamura (ES) is mainly distributed in the coastal areas of the middle Pacific, around Korea and Japan, and has a long-standing edible value. It is rich in various compounds, such as polysaccharides, fatty acids, alginic acid, fucoxanthin, and phlorotannins, among which the polyphenol compound phlorotannins are the main active ingredients. Studies have shown that the extracts and active components of ES exhibit anti-cancer, antioxidant, anti-obesity, anti-diabetic, antibacterial, cardioprotective, immunomodulatory, and other pharmacological properties in vivo and in vitro. Although ES contains a variety of bioactive compounds, it is not widely known and has not been extensively studied. Based on its potential health benefits, it is expected to play an important role in improving the nutritional value of food both economically and medically. Therefore, ES needs to be better understood and developed so that it can be utilized in the development and application of marine medicines, functional foods, bioactive substances, and in many other fields. This review provides a comprehensive overview of the bioactivities and bioactive compounds of ES to promote in-depth research and a reference for the comprehensive utilization of ES in the future.

Influence of laboratory conditions on two species Dictyotaceae family (Phaeophyceae): Diterpenoid profile and physiological response

“…Some studies have speculated that the increase in fucosterol content may be the algae's response to maintaining cell membrane integrity during periods of lower temperatures and restricted photosynthetic periods (Terasaki et al, 2017). It is important to highlight that fucosterol is the main phytohormone present in macroalgae of the Phaeophyceae class, accounting for up to 97% of the total content of compounds in this class (Men et al, 2022). In addition, it has shown therapeutic potential, being able to act as an anti-inflammatory, antioxidant, anti-diabetic, anti-Alzheimer's, anticancer and hepatoprotective agent (Bakar et al, 2019;Meinita et al, 2021;Wang et al, 2022).…”
