IPC 56th 2004, Abstract No. G-5. HPTLC of conessine in Holarrhena antidysentrica, an important ayurvedic drug, on silica gel with toluene - ethyl acetate - diethyl amine 13:5:2. Detection by spraying with Dragendroff’s reagent. Quantitative determination by densitometric scanning at 520 nm. Different market samples of the drug were found to contain 0.30 - 1.46 % of conessine with recovery of 95.18 - 102.70 %
J. Planar Chromatogr. 17, 238-240 (2004). HPTLC of aceclofenac and mosapride citrate (as internal standard) on silica gel in a twin-trough chamber equilibrated with the mobile phase with toluene - methanol - ethyl acetate - glacial acetic acid 550:250:200:1. Quantitative determination by densitometry at 284 nm.
J. AOAC Int. 88, 1516 (2005). Short overview on the use of densitometry in thin-layer chromatography as one of the most active areas in TLC research. See also the biennial reviews of Planar Chromatography by J. Sherma in Anal. Chem 74, 2653-2662 (2002) and 76, 3251-3261 (2004).
J. Planar Chromatogr. 18, 400-402 (2005). HPTLC of beta-carotene on silica gel and RP-18 with preadsorbent sample-application zones (prewashed with dichloromethane - methanol 1:1) with petroleum ether (35-60 °C) - acetonitrile - methanol 1:2:2 or petroleum ether (20-40°C) - acetone 7:3. HPTLC of biliverdin on silica gel with n-butanol - methanol - water 4:2:3. Quantitative determination by absorbance measurement at 628 nm.
J. Planar Chromatogr. 18, 269-273 (2005). HPTLC of flavonoids (hyperoside, isoquercitrin, luteolin, luteolin 7-O glucoside, rutin, vitexin, quercetin, quercitrin as standards) and phenolic acids (caffeic and chlorogenic acid) on silica gel after presaturation with ethyl acetate - acetic acid - formic acid - water 100:11:11:26. Detection by spraying with natural products reagent, followed by spraying with PEG. Visualization under UV light at 254 and 366 nm. Quantitative evaluation by video-densitometry.
J. AOAC Int. 88, 1517-1524 (2005). HPTLC of fenofibrate and gemfibrozil on diol phases in horizontal chambers using the sandwich technique with hexane - tetrahydrofuran 4:1. Quantitative determination by classical densitometry at 227 nm and videodensitometry at 254 nm. Recovery in the densitometric assay was 101.4 % for fenofibrate and 100.5 % for gemfibrozil. Videodensitometry resulted in recoveries of 102.7 % and 98.8 %, respectively.
J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (3), 272-275 (2005). TLC of the extracts on silica gel with 1) n-hexane - chloroform - methanol 15:8:2; 2) n-hexane - ethyl acetate 9:1; 3) chloroform - benzene - glacial acetic acid 7:2:1. Detection 1) by exposing to iodine vapours; 2) under UV 365 and 254 nm. Identification by comparison with the standard. Quantification of usnic acid by densitometry at 290 nm. Validation by investigating the linearity range (0.50 - 2.50 µg/spot, r = 0.999), precision (RSD = 2.26 %, n= 5, within plate, and 2.97 %, n = 5, plate-to-plate), and standard addition recovery (97.5 %, RSD = 2.61, n = 5).
Indian Drugs 42 (12), 805-807 (2005). HPTLC of alprazolam and sertraline in tablet dosage form on silica gel with toluene - ethyl acetate - methanol - acetic acid 90:30:20:3 without saturation. Quantitative determination by absorbance measurement at 217 nm. Accuracy, precision, and linearity were established. The linearity range was 20-100 ng for alprazolam and 100-500 ng for sertraline. Recovery rates were between 99.8-100.5 % for both drugs.
