Chinese J. Trad. Patent Med. (Zhongchengyao) 26 (8), Appendix 16-18 (2004). Study of the identification of Shenbao capsules by TLC, in addition to microscopy and chemical methods. TLC of Shenbao capsule extracts on silica gel with 1) the lower phase of chloroform - ethyl acetate - methanol - water 15:40:22:10; 2) toluene - methanol 4:1. Detection 1) by spraying with 10 % H2SO4 in ethanol followed by heating at 105 ºC; 2) under UV light. Identification by fingerprint technique. Combination of the procedure with microscopy and chemical methods allows identification of all drug ingredients.

HPTLC of an inclusion complex of coenzyme Q10 with beta-cyclodextrin on silica gel by one-dimensional, two-dimensional, and multi-dimensional separation with 1) dioxane - water 1:1 and 2) chloroform - methanol 11:9. Detection by spraying with 5 % phosphomolybdic acid in ethanol and drying at 110 °C, followed by spraying with 50 % sulfuric acid and heating at 120 °C for 5 min.
Chinese J. Trad. Pat. Med. (Zhongchengyao) 27(1), 94-96 (2005). HPTLC on silica gel with 1) n-butanol - glacial acid - water 19:5:5; 2) petroleum ether (30-60 ºC) - formic acetate - formic acid 15:5:1; 3) chloroform - ethyl acetate - methanol - formic acid 200:25:50:1. Detection 1) by spraying with 0.5 % ninhydrin in ethanol; 2) under UV 365 nm; 3) by spraying with vanillin - H2SO4 solution and heating. Identification by fingerprint technique. Quantification of emodin by densitometry at 440 nm. Validation of the method by investigation of linearity (0.1 µg - 0.5 µg, r = 0.998); precision (RSD = 3.8 %, n = 15 within plate and RSD = 3.2 %, n = 5 plate to plate); reproducibility of five time assay towards the same sample (RSD = 4.4 %); standard addition recovery (99.5 %, RSD = 2.2 %, n = 5). The results for some real life samples are given.
56th IPC 2004, Abstract No. GP-47. Stability indicating HPTLC determination of oxcarbazepine in tablet dosage form on silica gel with toluene - methanol 4:1. The Rf value of oxcarbazepine was 0.17. Quantitative determination by scanning at 255 nm. The compound was subjected to acid and alkali hydrolysis, oxidation, dry heat, and photo degradation. All degraded products were well resolved from the pure drug. The method was validated for accuracy, precision, linearity, robustness, and recovery.
J. Planar Chromatogr. 18, 437-442 (2005). HPTLC of quercetin and kaempferol in horizontal chambers on silica gel (prewashed with methanol) with four mobile phases, e.g.1,4-dioxane - toluene - 85 % acetic acid 6:24:1 or on cellulose with five mobile phases. Evaluation under UV light at 254 and 366 nm before and after spraying with a 2 % solution of zirconium (IV) dichloride oxide in methanol. Quantitative determination by absorbance measurement at 373 for quercetin and at 347 nm for kaempferol.
J. Planar Chromatogr. 18, 78-84 (2005). HPTLC of alkaloid standards (boldine, berberine, emetine, glaucine, codeine, laudanosine, narceine, narcotine, noscapine, papaverine, protopine, tubocurarine, atropine, hyoscyamine, scopolamine, quinine, cinchonine, brucine, yohimbine, strychnine, caffeine, novocaine) on silica gel with a variety of aqueous and nonaqueous mobile phases. Location of spots under UV light at 254 nm. Densitometry at 254 nm. Systems with the best selectivity and efficiency were used to separate alkaloid standard mixtures and plant extracts by 2D-TLC (e. g. methanol - water 4:1, containing 1 % ammonia, in the first direction and methanol - acetone - diisopropyl ether - diethylamine 15:15:69:1 in the second direction).
