J. Planar Chromatogr. 18, 167-170 (2005). TLC and HPTLC of saponins from 70 species of Acer on silica gel in a horizontal chamber with chloroform - methanol - formic acid - water 200:80:20:19. Detection by spraying with 10 % sulfuric acid in ethanol or anisaldehyde - sulfuric acid reagent, followed by heating at 110 °C for 5 min, and evaluation in visible and UV light at 366 nm. Detection also by spraying with water or blood reagent.

J. Planar Chromatogr. 18, 164-166 (2005). TLC of non-steroidal anti-inflammatory drugs (NSAID), i.e. mefenamic acid, naproxen, ibuprofen, flurbiprofen, ketoprofen, paracetamol, and diclofenac, on silica gel with chloroform - methanol , chloroform - ethyl acetate, acetonitrile - methanol - water, acetonitril - methanol in different proportions. Detection with iodine vapor.

J. Planar Chromatogr. 18, 432-436 (2005). TLC of nine benzimidazole and benztriazole derivatives on silica gel impregnated with paraffin oil with methanol - water mixtures. After development the plates were dried and examined under UV light at 254 nm. A quantitative structure-retention relationship (QSRR) correlation study was performed.

J. AOAC Int. 88, 1562-1567 (2005). HPTLC of beta-asarone (cis-2,4,5-trimethoxy-1-propenylbenzene) and alpha-asarone in Calamus rhizome on caffeine-impregnated silica gel (prepared by immmersion of conventional silica gel plates into a solution of 80 g/L caffeine in dichloromethane for 1 s followed by drying at room temperature for 5 min, then heating at 80 °C for 5 min) with toluene - ethyl acetate 93:7. Quantitative determination by absorbance measurement at 313 nm. The method was validated in terms of stability of sample during chromatography, specificity for beta-asarone, linearity (25-300 ng, including samples containing 0.05-0.7 % beta-asarone), accuracy and precision. Recovery was 100.0-100.8 %, limit of detection 6.4 ng, and limit of quantitation 12.7 ng. The method allows proper identification of Calami rhizoma raw material, and the specific, accurate, and precise quantification of beta-asarone and alpha-asarone
