摘 要:[目的]建立从龙胆碱性乙醇提取物中分离龙胆碱的高速逆流色谱(HSCCC)方法。[方法]采用高速逆流色谱仪分离纯化龙胆碱性乙醇提取物中的龙胆碱,通过优化溶剂系统,以正己烷∶乙酸乙酯∶甲醇∶水(5∶5∶4∶6)为溶剂体系,上相为固定相,下相为流动相,仪器转速为850 r/min,流速为1.5 m L/min,温度为25℃,检测波长为280 nm。[结果]龙胆碱性乙醇提取物经过D151弱酸性阳离子交换树脂富集(20%乙醇洗脱部分),再采用HSCCC技术进行分离纯化,制备得到的98.8%纯度的龙胆碱。[结论]该方法稳定、回收率高,可高效地从龙胆碱性乙醇提取物中分离龙胆碱。[Objective] To establish the HSCCC method for separating the gentianine from the alkaline ethanol extracts of gentiana. [Methods] Separation and purification of gentianine by TBE300B HSCCC technology, through the optimization of the solvent system, with n-hexane : ethyl acetate : methanol : water (5:5:4:6) as the solvent system, the upper as stationary phase and the next phase as mobile phase, the rotational speed of the instrument was 850 r/rain, the flow rate was 1.5 mL/min, the temperature was 25 ~C, the detection wavelength was 280 nm. [Results] The gentianine was obtained from the gentian alkaline ethanol extracts by D151 cation exchange resin combining with HSCCC, the content was above 98.8%. [Conclusion] The method is stable and has high results, it could he used to separate gentianine efficiently from alkaline ethanol extract of gentiana.
