Title: Study on Extracting and Refining of the Pigments from Lycium ruthenicum Murr.
Abstract: The extracting and refining technology of pigment of Lycium ruthenicum Murr.is studied by orthogonal design in the paper.The results showed that the best extracting conditions were 80% ethanol using 40 times volume,pH 3.0,50 ℃,3 hour;The X-5 macroporous resin is used to refine the pigment.The best adsorption conditions are 1 g/L pigment solution,pH 3.0,3 mL/min,resin diament vs height:1:15,whose adsorption capacity is 0.03715 g/mL wet resin;The 95% ethanol as eluting solvent,pH 2.0,5 mL/min,3 BV eluting solvent volume are the best desorption conditions.The pigment can be recovered more than 97.78% of that all.The pigment produced by this method is purple,and its colour value is 36.7.
