Abstract: A composition for use in the treatment and/or prevention of adverse side effects induced by an anti-cancer compound, said composition comprising an aqueous liquid extract, the aqueous liquid extract comprising Phycocyanin. The present invention also relates to the use of this aqueous liquid extract comprising Phycocyanin and optionally Spirulina polysaccharides, for the treatment and/or prevention of adverse side effects induced by an anti-cancer compound. Indeed, Phycocyanin, thanks to its antioxidant effects, can reduce the undesirable side effects induced by an anti-cancer compound.

Abstract: Composition comprising an aqueous liquid extract of phycobiliproteins, containing phycocyanin, which is obtained from cyanobacteria or micro-algae and which has not been subjected to any drying step, said composition being used to prevent or treat lipido-carbohydrate metabolism disorders in humans or mammals. In particular, the composition can be used to prevent or treat non-alcoholic hepatic steatosis or steatohepatitis.

Abstract: A method for preparing a liquid extract rich in phycocyanin from cyanobacteria or microalgae containing phycocyanin in solution, comprising a step of carrying out the cellular lysis of an aqueous suspension of said fresh cyanobacteria or microalgae, a step of macerating the lysate obtained, for several hours in a solution of divalent cations, while releasing the water-soluble molecules in the extracellular space, and one or more steps of clarifying and concentrating the suspension in order to isolate the water-soluble molecules, among them phycocyanin. This method is performed at a pH between 5 and 8.5, at room temperature, without drying.
