A randomized controlled double-blind clinical trial comparing versus placebo the effect of an edible algal extract (Ulva Lactuca) on the component of depression in healthy volunteers with anhedonia.

Background: The effects of the seaweed extract were evaluated on the animal model equivalent of depression compared with a control group treated with the carrier (spring water) and a reference group treated with Imipramine and showed significative effect. This clinical trial was intended to confirm in humans the potential efficacy identified in animals. The primary objective was to compare against a placebo the effect of Ulva L.

Evaluation of the antidepressant- and anxiolytic-like effects of a hydrophilic extract from the green seaweed Ulva sp. in rats.

Objectives: The green seaweed Ulva sp. contains a large amount of ulvans, a family of sulphated polysaccharides. The present study was designed to investigate in rats the antidepressant- and anxiolytic-like effects of a hydrophilic extract of Ulva sp.

Green nanocomposites: synthesis and characterization.

A series of intercalated and exfoliated nanocomposites montmorillonite-ulvan was prepared. Ulvan, extracted from the green algae, is a water-soluble polysaccharide biopolymer. Depending on the drying process, air or freeze drying, ulvan were inserted in the interlayer space or adsorbed on the both sides of inorganic layers.
