以离子液体和三乙胺作流动相添加剂分离苦参中的生物碱
, PP. 117-120
Keywords: 离子液体,苦参碱,三乙胺,hplc,添加剂
Abstract:
分别用离子液体1丁基3甲基咪唑四氟硼酸盐(bmimbf4)和三乙胺(tea)作流动相添加剂，用高效液相色谱法分离苦参中的生物碱，并分别考察添加剂浓度对组分保留和分离效率的影响，对两种添加剂的分离效果做了比较研究，同时对分离机制做了初步探讨。结果表明：离子液体作添加剂能够使苦参中的生物碱达到完全分离，减少试样的拖尾峰，改善峰形，提高分离效率。与tea体系相比，生物碱的保留值降低幅度较小。在相同浓度下，分离效能较高。添加量提高时，组分的保留值减小。
