摘要:改变溶剂系统中各组分的比例、体系的温度、pH,通过测定分配系数和分层时间选择适宜于高速逆流色谱(HSCCC)分离红霉素A的溶剂系统。结果表明:适宜于HSCCC分离红霉素A的溶剂系统组成为V(正己烷)∶V(乙酸乙酯)∶V(甲醇)∶V(水)分别为3∶5∶5∶5,3∶6∶5∶5,4∶7∶5∶5,6∶10∶6∶5,5∶5∶4∶5,体系温度为20-30℃,体系pH为7-10。实践证明当pH=7,T=298 K时,选取3∶6∶5∶5的溶剂系统用HSCCC分离红霉素A,其纯度为99.99%。
Solvent systems with different compositions were compared by measuring their partition coefficients and settling times at different temperatures and pH in separating erythromycin A by high-speed counter current chromatography. The optimal solvent systems were found to be V(n-Hexane) : V(Ethyl acetate) :V(Methanol) : V(Water)=3 : 5 : 5: 5, 3 : 6 : 5 : 5, 4 : 7 : 5 : 5, 6 : 10 : 6 : 5, 5 : 5 : 4 : 5 and the appropriate temperature was 20-30 ℃, pH was 7 - 10. A practical use of one of these solvent systems composed of V(Hexane) : V(Ethyl acetate) : V(Methanol) : V(Water)=3 : 6 : 5 : 5 at the condition of pH=7, T=298 K was demonstrated its applicability in separating erythromycin A by HSCCC.
