      High performance thin layer chromatographic determination of the related substances in alprazolam drug
      Y. ANJANEYULU*, R. MARAYYA, D. LINGA RAO, P. KRISHNA RAO (*Natco Pharma Ltd. QC / QA Chemical Div., Road No.2, Banjara Hills, Hyderabad 500033, India, mekaguda@natcopharma.co.in)

      Asian J. Chem. 19(5), 3375-3381 (2007). The TLC method described in USP 28 does not separate all the related substances of alprazolam. An alternative HPTLC method is described for separation and estimation of starting material and synthesis related intermediates in alprazolam: 2-chloro acetamide-5-chloro benzophenone (impurity 1) i.e. starting material, nordiazepam (impurity 2), thionordiazepam (impurity 3), 2-(2-aceto hydrazinyl)-7-chloro-5-phenyl-3H-1, 4-benzodiazapine (impurity 4). The hRf values of alprazolam, impurity 4, impurity 3, impurity 2, and impurity 1 were 25, 16, 77, 45, and 83 respectively. The HPTLC method developed is capable of detecting impurities at a level of 0.05%.

      HPTLC METHOD FOR SIMULTANEOUS ESTIMATION OF RABEPRAZOLE SODIUM AND ITOPRIDE HYDROCHLORIDE IN CAPSULE AND BULK DRUG
      S. Mageswari*, K. Surendra, R. Maheswari, N. Krishnan, C. Roosewelt, V. Gunasekaran (*Dept. of Pharmaceutical Analysis, Vel’s College of Pharmacy, Pallavaram, Chennai 600117, India, kalavaivgs30@rediffmail.com)

      Asian J. Chem. 19(7), 5634-5638 (2007). TLC of rabeprazole sodium and itopride hydrochloride on silica gel prewashed with methanol, with toluene - chloroform - methanol - 25 % ammonia 5:6:2. Quantitative determination by absorbance measurement at 225 nm. Linearity was between 120 and 280 µg/mL for rabeprazole sodium and 900 and 1900 µg/mL for itopride hydrochloride. The recovery (by standard addition method) was between 98.1 and 99.5 % for both drugs. The proposed method is precise and accurate and can be used for routine analysis of rabeprazole sodium and itopride hydrochloride in capsule formulation.
