摘 要:采用反相高效液相色谱法分离和测定(反)-4-环已基-L-脯氨酸和(反)-4-苯基-L-脯氨酸.在选定的色谱条件下,(反)-4-环已基-L-脯氨酸、(反)-4-苯基-L-脯氨酸和杂质之间具有较好的分离效果.该方法具有操作简单、快速、准确度和精密度较好,对同一(反)-4-环已基-L-脯氨酸试样多次测定,(反)-4-环已基-L-脯氨酸的日内、日间相对标准偏差(RSD)分别1.55%和0.09%;(反)-4-苯基-L-脯氨酸的日内、日间相对标准偏差(RSD)分别1.94%和1.79%.(反)-4-环已基-L-脯氨酸和(反)-4-苯基-L-脯氨酸的回收率分别为99.80%~100.40%和97.28%~100.00%.(Trans)-4-cyclohexyl-L-proline and (trans)-4-phenyl-L-proline has been separated and determined by reversed-phase HPLC. The separation efficiency of (trans)-4-cyclohexyl-L- proline, (trans)-4-phenyl-L-proline and other impurities was high under the selected conditions of the chromatographic operation. The accuracy and precision of this method were satisfied. The repeated tests of (trans)-4-cyclohexyl-L-proline sample showed that RSD of inter-day and intraday for (trans)-4-cyclohexyl-L-proline were 1.55% and 0.09% respectively, while RSD of interday and intra-day for (trans)-4-phenyl-L-proline were 1.94%和 1.79 % respectively. The recovery of (trans)-4-cyclohexyl-L-proline and ( trans)-4-phenyl-L-proline were 99.80 %- 100.40 % and 97.28%-100.00%.
