J. Chinese Trad. Patent Med. (Zhongchengyao) 26 (2), 172-173 (2004). TLC on silica gel with 1) benzene - acetone - ethyl acetate - conc. ammonia 10:15:20:2. Detection by spraying with 5 % potassium iodobismuthate solution. Identification by comparison with the standard. Quantification by densitometry at 524 nm. The procedure is validated by investigation of its repeatability, reproducibility, and recovery. Discussion of the merits of the procedure compared to that in China Pharmacopeia (2000 ed).

Detection 1) by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC; 2) under UV 254 nm; 3) by spraying with 5 % vanillin - H2SO4 solution and heating at 105 ºC. Identification by finger print technique. Quantification of astragaloside by densitometry at 530 nm.
J. Chinese Trad. Patent Med. (Zhongchengyao) 26 (1), 23-26 (2004). TLC on silica gel with 1) chloroform - methanol - water 28:10:1, 2) n-hexane - ethyl acetate 9:1, 3) chloroform - methanol 5:1, 4) petroleum ether - diethyl ether 1:1. Detection 1) under UV 365 nm, 2) by spraying with 5 % vanillin in H2SO4 solution. Identification by fingerprint techniques. Quantitative determination of puerarin by HPLC.
J. AOAC Int. 86, 453-460 (2003). HPTLC of baicalein, baicalin, ikonnokoside I, verbascoside, and teucroside on pre-washed silica gel with ethyl acetate - formic acid - acetic acid - water 100:11:11:25 in a twin trough chamber. Evaluation under UV light at 254 and 365 nm. Detection by spraying with NP (Natural Products) reagent (0.5 g diphenylboric acid aminoethylester dissolved in 50 mL methanol) and evaluation under UV 365 nm, followed by spraying with PEG (2.5 mL PEG dissolved in 50 mL ethanol), drying for 5 min, and evaluation under UV 365 nm.
Chinese J. Chromatogr. (Sepu) 22 (3), 296-297 (2004). TLC of rhodojaponin III on silica gel with chloroform - methanol 9:1. Detection by spraying with 10 % H2SO4 in ethanol and heating. Identification by comparison with the standard. Quantification by densitometry at 550 nm. Validation of the method by investigating its linearity range (0.1-4.0 µg/spot, r=0.997), precision (RSD=1.30-3.34 %, n=8), and recovery (95.4-101.5 %, RSD=1.97 %, n=5).
Chinese J. Trad. Patent Med. (Zhongchengyao) 26 (4), Appendix 5-6 (2004). TLC of Dabaidu capsules on silica gel with benzene - ethyl acetate - methanol - isopropanol - ammonia 12:6:3:3:1. Detection under UV light. Identification by comparison with the standard. Quantification by fluorescence measurement at 366 nm. Validation of the method by investigation of precision (RSD<2 %), linearity range, repeatability, reproducibility, recovery, and limit of detection (1.2 ng).
Indian Drugs 41 (5), 300-302 (2004). Validated HPTLC method for the estimation of stavudine in capsules on silica gel with toluene - methanol 3:1. Quantitative determination by absorbance measurement at 270 nm. The linearity range of stavudine was 1.4 µg to 3.7 µg. The amount of stavudine estimated was 40.08 mg and 40.01 mg (calculated by peak height and peak area respecively) in the average weight capsule. Recovery was 99.67 % and 99.26 % calculated by peak height and peak area respectively. The proposed method is accurate, precise, selective, and reproducible and can be used for the routine analysis of stavudine.
J. Planar Chromatogr. 17, 280-285 (2004).
