CBS 91, 12-13 (2003). HPTLC of flavonoids with tetrahydrofuran - toluene - formic acid - water 16:8:2:1, diterpenes with toluene - ethyl acetate 9:2, and iridoids with ethyl acetate - methanol - water 77:15:8 (with chamber saturation), in horizontal developing chamber over 52 mm. Detection of flavonoids by dipping warm plate in natural products reagent (0.5 % in ethyl acetate) followed by dipping in PEG 400 solution (5 % in dichloromethane), of diterpenes by dipping in 10 % methanolic sulfuric acid followed by heating at 105 °C, and iridoids by dipping in 4-dimethylaminobenzaldehyde reagent (1 % in 1 N methanolic HCl). Visual evaluation at 366 nm (flavonoids), white light (diterpenes), and white light with sharp cut filter 560 nm (iridoids). Stability of extracts was investigated under drastic stress conditions (acid, base, light, heat, humidity).
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (8), 651-653 (2004). TLC on silica gel with n-butanol - ethyl acetate - ammonia 10% 4:1:5. Detection by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC for 5-7 min. Identification by standard comparison. Quantification by densitometry at 530 nm. Validation of the procedure by investigation of its precision, specificity, repeatability, reproducibility, recovery, etc. Determination of the title compound in the extracts from five batches of the drug.
Chinese J. Trad. Patent Med. (Zhongchengyao) 26 (5), 371-373 (2004). TLC of Xiaozhi tablet extracts on silica gel with 1) ethyl acetate - formic acid - water 5:2:1; 2) benzene - acetone - ethyl acetate - ammonia 4:6:8:1; 3) chloroform - methanol - ammonia 40:10:1. Detection 1) under UV light; 2) by spraying with 5 % solution of potassium iodobismuthate. Identification by fingerprint techniques. Quantification of matrine by HPLC with method validation.
J. Planar Chromatogr. 17, 123-127 (2004). TLC of 5 fibrate-type drugs (bezafibrate, ciprofibrate, clofibrate, clofibric acid, fenofibrate, and gemfibrozil) on RP 18-, RP 8- and cyano-phase in horizontal chambers with chamber saturation with a phosphate buffer and different amounts of six modifiers, i.e. acetone, acetonitrile, dioxane, isopropanol, methanol, and tetrahydrofuran. The best separation of all drugs investigated was obtained with dioxane - pH 7.60 phosphate buffer 7:3. Visualization under UV light at 254 nm. Quantitative determination at 227 nm.

Detection 1) by spraying with 2,4-dinitro-phenylhydrazine solution in ethanol; 2) by spraying with 5 % vanillin-H2SO4 solution and heating at 110 ºC for 5 min. Identification by fingerprint techniques. Quantification of menthol and camphor by GC.
Chinese J. Trad. Pat. Med. (Zhongchengyao) 27(2), 167-169 (2005).
