摘要
A kind of simple aqueous two-phase system composed of acetone,inorganic salt and water was used to separate and purify carthamine from safflower petals.Experimental results show that(NH4)2SO4 has the stronger phases-forming ability than K2HPO4 and NaCl.The optimum conditions for isolating carthamine from safflower yellow were chose as V(CH3)2CO=5mL,VH2O=5mL,m(NH4)2SO4=2.5g.Under the conditions,the yield can reach to 99 % for the extraction of carthamine with the partition coefficient K>55.The carthamine product with high purity was obtained using analog counter-current extracting experiment.
A kind of simple aqueous two - phase system composed of acetone, inorganic salt and water was used to separate and purify carthamine from safflower petals. Experimental results show that （NH4 ）2SO4 has the stronger phases -forming ability than K2 HPO4 and NaCl. The optimum conditions for isolating carthamine from safflower yellow were chose as V（ CH3 ）2 CO = 5mL, VH2O =5mL,m（NH4）2SO4 =2.5g. Under the conditions, the yield can reach to 99 % for the extraction of carthamine with the partition coefficient K 〉 55. The earthamine product with high purity was obtained using analog counter - current extracting experiment .
