Abstract
A simple and rapid reverse-phase HPLC method was developed for determination of Teneligliptin (TGP) in the presence of its degradation products generated from forced decomposition studies. The HPLC separation was achieved on a C18 ACE column (150x 4.6 mm i.d.; 5 μm) using mobile phase as a mixture of Phosphate buffer pH-7.2 using ortho-phosphoric acid: methanol (30:70v/v). The UV detection was carried out at 245nm at ambient temperature and the flow rate of 1.0 mL/min. The calibration curve was found to be linear in the concentration range of 10-50 μg/mL(r=0.9993). Force degradation study was performed under various conditions like acidic, alkaline, oxidative, photolytic and mass balance calculations were carried out from the degradation results. The developed method was validated as per ICH guidelines with respect to linearity, accuracy, precision, limit of detection and quantification. The robustness of the proposed method was evaluated by the Plackett Burman design. The purity of the degraded sample was checked by peak purity analysis. The peaks of degradation products did not interfere with that of pure Teneligliptin.
