摘要: 采用柱上衍生化学法,在较短的时间内,用羰基咪唑活化的氨丙基硅胶与牛血清白蛋白反应,合成出牛血清白蛋白键合手性固定相.分别考察了流动相pH值和有机改性剂正丙醇浓度对D,L-色氨酸的保留因子k和分离因子α的影响,并对7种对映异构体成功地进行了拆分.

Abstract: An HPLCchiral stationary phase was synthesized by the in situ covalent immobilization of bovine serum albumin on a aminopropyl silica packed column activated with 1, 1 carbonyldiimidazole in a short time. The effects of mobile phase pHand the content of 1 propanol on k' and α of D, L-trypto-phan were investigated, and the resolution of seven chiral compounds was successfully achieved.

Key words: Chiral separation, Bovine serum albumin, Aminopropyl silica gel, 1,1-Carbonyldiimidazole, Chiral stationary phase
