& Perry. J. AOAC Int. 91, 1169-1173 (2008). HPTLC of gallic acid, caffeic acid, and syringic acid (in clove) on silica gel with toluene - ethyl acetate - formic acid 8:2:1 in a twin-trough chamber. Quantitative determination by absorbance measurement at 280 nm.
Asian J. Chem. 19(5), 3621-3636 (2007). TLC of ornidazole and cefixime on silica gel with methanol - water 3:2. Quantitative determination by absorbance measurement at 254 nm. Linearity was between 250 and 2500 µg/mL for ornidazole and 100 and 900 µg/mL for cefixime. The recoveries of drugs by standard addition method were found in the range of 98.0 and 89.4 % for both drugs. The method is suitable for routine quality control.
obtained by use of different techniques. J. Planar Chromatogr. 22, 25-28 (2009). HPTLC of flavonoids (rosmarinic acid and luteoline) on silica gel with ethyl acetate - formic acid - water 136:5:6, ethyl acetate - methanol - water 77:13:10, ethyl acetate - diethyl ether 4:1, n-hexane - ethyl acetate - formic acid 60:40:3, chloroform - methanol - formic acid 882:60:47, and chloroform - acetone - formic acid 19:4:2. The mobile phase chosen for quantification was chloroform - ethyl acetate - formic acid 60:40:3. Detection by spraying with natural products reagent, followed by polyethylene glycol 400 reagent. Quantitative determination by densitometry at 328 nm (rosmarinic acid) and 349 nm (luteoline).
J. Planar Chromatogr. 22, 183-186 (2009). HPTLC of ethyl 8-oxo-5,6,7,8-tetrahydrothiazolo[3,2-a][1,3]diazepin-3-carboxylate (HIE-124) in plasma (with diazepam as internal standard) on silica gel with chloroform - ethyl acetate 4:1 with chamber saturation for 30 min. Quantitative determination by absorbance measurement at 265 nm. The limit of detection and quantification was 20 µg/L (40 ng/band) and 40 µg/L (80 ng/band), respectively.
J. Planar Chromatogr. 22, 115-119 (2009). HPTLC of metoprolol succinate and amlodipine besylate on silica gel (prewashed with methanol) with methanol - ethyl acetate - water - toluene - 25 % ammonia 15:50:3:30:3 in a twin trough chamber saturated for 20 min at 25 +/- 2 °C. Quantitative determination by absorbance measurement at 236 nm.
Ind. J. Pharm. Sci. 70(5), 689-693 (2008). HPTLC of andrographolide and wedelolactone (active components of Andrographis paniculata respectively Eclipta alba) on silica gel with toluene - acetone - formic acid 9:6:1. Quantitative determination by absorbance measurement at 254 nm. The hRf of andrographolide was 52 and of wedelolactone 58. The method was linear in the range of 200-400 ng/spot (andrographolide) and 100-200 ng/spot (wedelolactone). The herbal formulation contained 1.4 mg andrographolide and 1.7 mg wedelolactone per tablet. The proposed method could be applied for routine analysis of both compounds.
Ind. J. of Pharma Sci. 70(6), 844-847 (2008). HPTLC of plumbagin in alcoholic root extracts of Plumbago indica and Plumbago zeylanica on silica gel with n-hexane - ethyl acetate 4:1. The hRf value of plumbagin was 67. Quantitative determination by absorbance measurement at 265 nm. Plumbago indica showed significantly higher plumbagin contents than P. zeylanica. The HPTLC method was the method of choice for simultaneous analysis of several samples, whereas the RP-HPLC method was very sensitive.
Alpha-hydroxybutyric and mandelic acids. J. Planar Chromatogr. 22, 241-248 (2009). TLC of alpha-hydroxybutyric acids and mandelic acid on silica gel, prewashed with methanol - water 9:1 and impregnated by dipping for 2 s in 0.05 g/L aqueous copper acetate solution, with dioxane - water 9:1 at 22 +/- 2°C. Quantitative determination by absorbance measurement during 16 days at 326 nm. Spontaneous oscillatory in-vitro chiral conversion was observed for alpha-substituted propionic acids as well as chiral carboxylic acids with two and four carbon atoms.
