Carrageenans extraction processes

Also andalusol (104), extracted from S. foetens, was able to inhibit acute inflammatory processes induced by carrageenan [126]. It operates also on the induction of nitric oxide synthase NOS in murine cultured macrophages J774 and is able to scavenge NO directly [127-128]. 

The aerial parts of Eupatorium articulatum L. (Compositae) are widely used in the Andes region of Ecuador for the treatment of inflammatory diseases. The methanolic extract of this species exhibited a significant in vivo anti-inflammatory activity, when tested for its ability to reduce carrageenan-induced inflammation in rat paw oedema, thus supporting the traditional use claimed for this plant. Since the inflammation process is associated to the generation of reactive oxygen species and the induction of lipid peroxidation, the antioxidant properties of the extract were also studied [45]. Significant activity was observed when tested for its ability... 

Carrageenans " are a family of high molecular weight sulfated polysaccharides. The structures strongly depend on the source and conditions during extraction and purification process. 

Carrageenan is frequently preferred over other thickening, suspending and binding ingredients, because it is natural, economical, readily available and functional in an extremely broad application base. Carrageenans can be produced via a variety of process techniques such as alcohol extraction, potassium chloride gel press or extraction with various alkalis. The process technique is important, because it influences the gel characteristics. Likewise, different seaweeds also influence the gel characteristics.
