J. Planar Chromatogr. 33, 219-229 (2020). HPTLC of carbamazepine (1) and its degradation product iminostilbene (2) on silica gel with petroleum ether - acetone 7:3. Quantitative determination by absorbance measurement at 230 nm. The hRF values for (1) and (2) were 12 and 63, respectively. Linearity was between 0.1 and 1.4 µg/zone for (1) and 0.1 and 1.2 µg/zone for (2). Intermediate precision was below 2 % (n=3). The LOD and LOQ were 0.03 and 0.09 µg/zone for (1) and 0.03 and 0.09 µg/zone for (2), respectively. Average recovery was 99.7 % for (1) and 99.7 % for (2).
J. Ethnopharmacol. 235, 361-374 (2019). HPTLC of colchicine (1) and withaferin A (2) in the polyherbal ayurvedic formulation Peedantak Vati (PV) on silica gel with chloroform -
methanol - water - formic acid 140:13:2:4. Quantitative determination by absorbance measurement at 218 nm. The hRF values for (1) and (2) were 22 and 28, respectively. LOD and LOQ were 40 and 120 ng/zone for (1) and 120 and 240 ng/zone for (2), respectively.
J. AOAC Int. 91, 1186-1190 (2008). TLC of N-(hydroxymethyl)nicotinamide on silica gel with chloroform - ethanol 2:3. Quantitative determination by absorbance measurement at 260 nm.
62nd Indian Pharmaceutical Congress Abstract No. F-290 (2010). TLC of ranolazine on silica gel with methanol – 10 mM ammonium acetate 3:2. The hRf value was 54. Quantitative determination by absorbance measurement at 271 nm. The recovery was 99.9 %.
Planta Medica 82, 09/10, 903-909 (2016). To monitor the sorbent phase purification of a chloroform subfraction of the sponge Myxilla incrustans, TLC of fractions on silica gel with dichloromethane – methanol – formic acid 900:100:1, detection with Dragendorff’s reagent. The four positive fractions were purified by preparative HPLC, yielding three new N-acyl dopamine/dehydrotyrosine glycosides: myxillins A, B and C._x000D_
J. Chromatogr. 472, 277-283 (1989). TLC of enantiomeric amides on naphtyl-ethyl-urea-aminopropyl-bonded silica with hexane - isopropanol - acetonitrile 20:8:1. Detection under UV 254/360 nm. Discussion of the preparation of the chiral stationary phase.
InCom-Sonderband 333-342 (1997). TLC of formaldehyde in dimedone adduct form (formaldemethone, 1,1',3,3'-tetraketo-5,5,5',5'-tetramethyl-2,2'-dicyclohexylmethane) and its main precursors (e.g. choline, L-carnitine, trigonelline, glycinebetaine) by means of personal OPLC on silica with chloroform - dichloromethane 7:13 for formaldemethone, acetone for residual dimedone, and with isopropanol - methanol - 0.1 M sodium acetate 20:3:30. Quantification by densitometry at 260 nm for formaldemethone, and at 525 nm for quaternary ammonium compounds after spraying with modified Dragendorff's reagent.
60th Indian Pharmaceutical Congress PA-49, (2008). HPTLC of alfuzosin hydrochloride on silica gel with toluene - methanol - triethyl amine 15:5:1. Densitometric evaluation at 245 nm. Linearity was in the range of 5-400 ng/spot. The method was stability indicating (acid, alkali, oxidation, dry and wet heat and photodegradation). The compound was stable to oxidation and alkaline degradation. The hRf value of the main zone was 63, and of additional zones 10 and 33. The method could effectively separate the main drug from the degradation products.
