J. Xian Med. Univ. (Xian Yike Daxue Xuebao) 12, 84-86 (1991). TLC of quinidine sulfate on silica with cyclohexane - chloroform - diethyl amine 5:4:2. Quantification by densitometry at 257 nm.
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%.
Chinese J. Pharm. (Zhongguo Yaoxue Zazhi) 28, 233-234 (1993). TLC of alprazolam on silica with cyclohexane - chloroform - diethylamine 50:40:11. Detection under UV 254 nm. Quantification by densitometry at 246 nm.
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.
J. Chinese Pharm. Univ. (Zhongguo Yaoke Daxue Xuebao) 26, 20-22 (1995). TLC on silica with 1) benzene - chloroform 3:2, 2) acetone - benzene - chloroform 5:8:10. Detection under UV 254 nm or 365 nm. Quantification by UV spectrometry after elution.
Ind. J. Pharm. Sci. 70(3), 386-390 (2008). HPTLC for the simultaneous estimation of ondansetron combinations in solid dosage form with omeprazole and rabeprazole, on silica gel with dichloromethane - methanol 9:1. Quantitative determination by absorbance measurement at 309 nm for combinations of ondansetron with omeprazole and at 294 nm for ondansetron with rabeprazole. The hRf value of ondansetron and omeprazole was 42 and 54, respectively, while for ondansetron and rabeprazole hRF values were 41 and 51 respectively. Linearity was between 100 and 500 ng/spot for three drugs. The method can be employed for routine quality control of such formulation.
Chromatographia 47, 101-104 (1998). TLC on silica gel with methanol - NH3. Detection under UV 321 nm and by spraying with terbium chloride solution and heating for 5 min at 100°C. Preparation of the sample by extraction and clean-up by solid-phase extraction on reversed-phase cartridges. The method has been validated to a level of 15 mg/kg for four and of 5 mg/kg for three quinoline residues.
Asian J. Chem. 19(7), 5647-5651 (2007). HPTLC of levofloxacin hemihydrate and ornidazole on silica gel with n-butanol - water - acetic acid 3:1:1. Quantitative determination by absorbance measurement at 366 nm. The method was linear in the range of 1050-1400 µg/mL and 2600-2900 µg/mL for levofloxacin and ornidazole respectively. The recovery was between 97.3 and 98.0 % for both drugs. The method was suitable for simultaneous estimation of both drugs in combined tablet dosage form.
