A stability indicating chiral high-performance liquid chromatographic (HPLC) method was developed and subsequently validated for the separation and simultaneous determination of S-(+)and R(-)-donepezil hydrochloride (DP) in tablet products. Baseline resolution was achieved by using Chiralcel-OJ-H column with a mobile phase consisted of(More)
Enantiomeric resolution of teratolol was achieved on a vancomycin macrocyclic antibiotic chiral stationary phase known as Chirobiotic V with UV detection set at 220 nm. The polar ionic mobile phase (PIM) consisted of methanol-glacial acetic acid-triethylamine (100:0.01:0.015, v/v/v) has been used at a flow rate of 0.8 ml min(-1) . The calibration curves in(More)
