A new method for mixoxanthophylls extractions

Description: The subject of the offer is a new method enabling the acquisition of mixoxanthophylls preparations of high purity from dye extracts from cells of Arthrospira platensis or other species cyanobacteria, regardless of the method used extraction techniques.

The subject of the offer is a new method enabling the acquisition of mixoxanthophylls preparations of high purity from dye extracts from cells of Arthrospira platensis or other species cyanobacteria. This method is based on a preliminary extracting dyes from cyanobacterial cells or A. platensis commercially available dry biomass into the liquid phase followed by isolation fraction containing mixoxanthophylls by single-step adsorption chromatography. The following advantages: • obtaining mixoxanthophylls as a pure substance in relatively large amounts using simple liquid chromatography (1 g fraction of glycosylated carotenoids from 5 L culture of A. platensis with an OD750 optical density of at least 0.5-0.8, or 1 g fraction of glycosylated carotenoids from 1000 g of dry biomass); • greater simplicity of the method compared to the current used methods; • confirmed by an independent laboratory high purity level (above 95%) of preparations containing mixoxanthophylls;
