J. Pharm. Sci. & Res. 2(2), 143-148 (2010). TLC of salbutamol sulphate (SS), bromhexine hydrochloride (BH), and etofylline (ET) in fixed dose formulation on hand-made silica gel plates with methanol – n-hexane 2:1. All three compounds were well separated with hRf values of 25 for SS, 71 for ET and 91 for BH. Detection at 254 nm as well as by exposure to iodine vapors. For spectophotometric quantification the bands of the selected drug in sample and standard mixture were scraped off, suspended in methanol, and the absorbance was measured at the maximum absorbance wavelength of each compound.
62nd Indian Pharmaceutical Congress Abstract No. F-249 (2010). TLC of risperidone and trihexyphenidyl hydrochloride on silica gel with methanol – chloroform – glacial acetic acid 160:40:0.1. Quantitative determination by absorbance measurement at 254 nm. The linearity was in the range of 20-60 µg/band and 10-30 µg/band for risperidone and trihexyphenidyl hydrochloride, respectively. The recovery was 99.4-99.9 % for both drugs.
Acta Chromatographica 21(2), 299-317 (2009). HPTLC of amtolmetin guacil on silica gel with toluene – ethyl acetate 2:3. Identification and quantification by densitometric analysis in absorbance mode at 320 nm. The samples were subjected to acidic and alkaline hydrolysis, oxidation, dry heat treatment, and photo-degradation. The method was suitable for stability studies and to study the kinetics of degradation of amtolmetin guacil.
Acta Chromatographica 22 (2), 297-305 (2010). Description of a simple, precise, and accurate method for simultaneous quantification of aspirin, atorvastatin calcium and clopidogrel bisulphate by HPTLC on silica gel with toluene – methanol - formic acid 65:35:1. The hRf values were 26, 47, and 78 for aspirin, atorvastatin calcium, and clopidogrel bisulphate, respectively. Quantification by densitometry at 254 nm. The precision intra-day and inter-day was in the ranges of 0.2–0.7 %RSD and 0.5–1.0 %RSD for aspirin, 0.4–0.9 %RSD and 0.4–0.6 %RSD for atorvastatin calcium, and 0.3–0.7 %RSD and 0.4–0.9 %RSD for clopidogrel bisulphate.
Yunan J. of Chinese Trad. Med. & Pharm. 31(10), 58-60 (2010). TLC of extracts of Cishushi suppository: 1) for Panax notoginseng, on silica gel with chloroform – methanol – water 14:6:1, detection by spraying with 10 % sulfuric acid in ethanol and heating at 105 ºC; 2) for Fructus Cnidii, on silica gel with petroleum ether (60-90 °C) – ethyl acetate 7:3, detection under UV 366 nm; 3) for Borneolum Syntheticum, on silica gel with toluene – ethyl acetate 19:1, detection by spraying with 5 % vanillin-sulfuric acid reagent and heating at 105 °C; 4) for Fructus Sophorae, on silica gel with chloroform – methanol – water – formic acid 700:300:50:1, detection by spraying with 1 % AlCl3 in ethanol, heating and evaluation under UV 366 nm.
Journal of Pharmacy Research 4(5), 1401-1404 (2011). HPTLC of fluconazole and its structurally related impurities, on silica gel (prewashed with methanol) with n-butanol - water - acetic acid 8:2:1 with chamber saturation for 20 min. The hRf value of fluconazole was 67 and of the two separated impurities 49 (impurity B) and 79 (impurity E). Quantitative determination by densitometry in absorbance mode at 254 nm. The method was linear in the range of 1-6 µg/band for fluconazole and 0.5-2.5 µg/band for both impurities.
Asian Journal of Chemistry 23(10), 4351-4354 (2011). HPTLC of nateglinide in tablet dosage form on silica gel with n-hexane - methanol - isopropanol 75:15:10. The hRf value was 56. Quantitative evaluation by absorbance measurement at 210 nm. The method was linear in the range of 300-1000 ng/band. The average recovery was 98.5 %.
J. Planar Chromatogr. 24, 295-300 (2011). TLC of Verbascum extracts (e. g. iridoids, and triterpene saponins) on silica gel in a horizontal chamber saturated with mobile phase for 10 min, by 2D separation with ethyl acetate - methanol - water 25 % ammonia 55:35:9:1 in the first direction and methanol - ethyl acetate - water - acetic acid 5:45:13:11 in a perpendicular direction. Detection by dipping in vanillin-sulfuric acid reagent for 1 s followed by heating for 10 min at 105 °C. The method was validated for its specifity, precision (repeatability and intermediate precision), stability, and robustness. Use of an image-processing program for the construction of an ’average’ fingerprint.
