Title: The process of achieving the highest degree of drug's purity of c-phycocyanin from spirulina alga
Inventor: HOSEINI FAHIME
Filed: 2019-03-31
Abstract: Spirulina platnaseus, is a multi-striated cyanobacterium prokaryotic and photosynthetic. The extraction and purification of c-phycocyanin from spirulina due to a wide range of drug activity, which is mainly attributed to C-phycocyanin, has definitive therapeutic properties. It provides 20 times more antioxidant activity than ascorbic acid (Karkos.2011). Among these, Spirulina has been reported to exhibit anti-inflammatory (Remirez.2002), anti- hyperlipidemic (Torres-Duran.2007), hypoglycemic(Lima.1999), antihypertensive (Torres- Duran.2007), anti-neoplastic (Mittal.1999), antiviral(Lee.2001), antianemic (Simsek.2009). All of these benefits are attributed to substances in Spirulina known as phycobiliproteins (C- phycocyanin, allophycocyanin, phycoerythrin and phycoerythrocyanin), which called phycobilisome (Hoseini.2013). C-phycocyanin is the major phycobiliprotein in Spirulina. This blue colored red fluorescing biliprotein of algae was first reported in 1928 by Lemberg. The isolation and testing of these phyco billy proteins has shown that the beneficial effects of all microalgae depend on them.Hence, they are considered as a real and effective biological agent (Eriksen.2008;Hoseini.2013). Therefore, maintaining valuable properties and improving the benefits of active biological substances such as C-phycocyanin is essential. Because the nature of its protein structure, is sensitive to temperature, light, pH, etc makes it difficult to achieve purity, especially the purity of the drug. To divine grace, We have devised a simple, fast and innovative way for the separation and purification of this bioactive material from its natural resources. The benefits and merits of the new invention is that we were able to achieve the highest purity of the drug in the world, which has a significant difference with the previous achievements in the world (The new achievement is more than 7 times the purity of the drug in the world). It is important that we achieved this degree of purity and maximum yield by minimizing the number of extraction and purification steps.
