摘要 目的:建立手性固定相正相高效液相色谱法拆分首次报道合成的 D、L-苯丙氨酸衍生物的光学异构体。方法:采用 O,L′-二(3,5-二甲基苯甲酰)-N,N′-二烯丙基-L-酒石酸肼(KR100-CHI-I DMB)手性色谱柱(4.6 mm×250mm,5μm),流动相为正己烷-无水乙醇-三氟醋酸(100:10:0.4),流速:0.5 mL·min^(-1),检测波长:220 nm。结果:除2,5-二氯-苯丙氨酸外的3对 D、L-卤代苯丙氨酸光学异构体得到了分离,并用建立的分离方法对酶拆分得到的卤代苯丙氨酸进行了纯度检查。结论:方法简单、灵敏,可用于检查卤代苯丙氨酸的纯度。 Objective: To establish a normal - phase high - performance liquid chromatographic method for the separation of halogen substituted Phenylalanine enantiomers. Method:Using O, O- bis (3,5 -dimethylbenzoxyl) -N, N' -dially- L- tartar diamide(4. 6 mm× 250 ram,5 μm) as a stationary phase ,separations were performed under an elution of a mixture of hexane - ethanol - trifluoroacetic acid( 100: 10: 0. 4) at a flow rate of 0. 5 mL · min^-1 The effects of various parameters on the separation were investigated and optimized. Results: Three pairs of halogen substituted Phenylalanine enantiomers were successfully separated. Conclusion:It showes that the method is simple, sensitive and is used to control the optical purity of halogen substituted phenylalanine.
