Direct Separation and Quantitative Determination of Transglimepiride by High Performance Liquid Chromatography Using an Amide Type Chiral Stationary Phase
Trans and cis glimepiride were directly separated by a new established high performance chromatographic method, which involved the use of Chirex 3005 column. Several parameters were studied. Simple and reliable separation was achieved, with the separation factor (α) 1.12 and the resolution factor ( R s) 1.86, when using the optimized mobile phase composed of n hexane:1,2 dicholoethane:methanol (88/8/4 by vol) at 25℃ and 1.8 mL/min . Standard linear calibration curve was established for trans...
