J. AOAC Int. 91, 1179-1185 (2008). HPTLC of harmine, harmaline, vasicine, and vasicinone on silica gel with ethyl acetate - methanol - ammonia 70:10:3 in a twin-trough chamber at 25 °C and 40 % relative humidity. Quantitative determination by absorbance measurement at 366 nm for harmine and harmaline, at 292 nm for vasicine, and at 233 nm for vasicinone.
Asian J. Chem. 19(6), 4925 - 4927 (2007). TLC of ezetimibe on silica gel with toluene - acetone 3:2. Quantitative determination by absorbance measurement at 233 nm. The hRf value was 52 for ezetimibe. Linearity was in the range of 300 to 2100 ng/spot. Recovery (by standard addition method) was 99-101 %.
J. Chromatogr. B 846 (1-2), 334-340 (2007). Salting-out TLC of sulphonamides on silica gel with aqueous solutions of salts (sulphates, chlorides, nitrates, phosphates, acetates, and thiocyanates) showed that the applied salts have different effects on the retention of sulphonamides according to Hofmeister's classification (e.g. kosmotropes, chaotropes and neutral). Parameters of the linear regression analysis were compared with QSAR data of dependences between the RM values and salt concentration. Chromatographic data obtained by salting-out TLC showed not only the physico-chemical properties of the examined compounds but also information about their activity. The method was suitable for prediction and classification of sulphonamide drugs by localization of other structurally similar compounds with antagonistic activity towards sulphonamides.
J. Planar Chromatogr. 21, 337-341 (2008). HPTLC of phospholipids (cholesterol, phosphatidylethanolamine, phosphatidylcholine, and lysophosphatidylcholine) on silica gel plates with a concentration zone (prewashed with dichloromethane - methanol 1:1) with chloroform - methanol - water 65:25:4 in a saturated twin trough chamber. Detection by spraying with aqueous copper sulfate reagent followed by heating. Quantitative determination by absorbance measurement at 370 nm. Ninhydrin spray reagent was used to confirm the presence of phosphatidylethanolamine. The limit of quantification was 250 ng/spot.
J. Chinese Trad. Patent Med. 30 (12), 1781-1785 (2008). TLC of Shenyi granule extracts on silica gel with 1) dichloromethane - ethyl acetate - petroleum ether (60-90 ºC) - methanol 20:14:6:1; 2) ethyl acetate - formic acid - glacial acetic acid - water 30:3:4:3; 3) toluene - ethyl acetate - formic acid 8:6:1; 4) chloroform - methanol - water 26:10:3. Detection 1) by spraying with 10 % sulfuric acid in ethanol and heating; 2) by spraying with iron(III) chloride solution; 3) by spraying with vanillin reagent. Identification by comparison with the standards glycyrrhizic acid and glycyrrhetinic acid.
J. Chinese Trad. Patent Med. 30 (11), 1642-1646 (2008). TLC of Yinao pill extracts on silica gel with 1) toluene - ethyl acetate 9:1; 2) benzene - ethyl acetate 3:2; 3) toluene - ethyl acetate - formic acid 28:8:1. Detection 1) by spraying with 10 % phosphomolybdic acid in ethanol and heating at 105 ºC; 2) by spraying with 10 % sulfuric acid in ethanol and heating at 105 ºC.
Abstract No. 9148, IHCB (2009). HPTLC of gallic acid in Emblica officinalis (an important constituent of Triphala, a popular ayurvedic formulation) on silica gel with toluene - ethyl acetate - formic acid 10:10:3. The hRf value of gallic acid was 45. Quantitative determination by absorbance measurement at 254 nm. The method was linear in the range of 150-530 ng/spot. The extract was found to contain 7.5 mg/g of gallic acid.
J. Planar Chromatogr. 22, 109-113 (2009). HPTLC of purpurin on silica gel with toluene - ethyl acetate - formic acid 98:2:1 in a twin trough chamber saturated for 20 min at 25 +/- 2 °C. Quantitative determination by absorbance measurement at 255 nm. The limit of detection and quantification was 50 and 100 ng/band, respectively.
