J. Pharm. Biomed. Anal. 36, 23-31 (2004). An HPTLC method is reported for stress degradation studies of guggulsterone in gum-resin exudates of comniphora mukul. The degradation was carried out under different ICH prescribed stress conditions, followed by development of a stability indicating HPTLC method. Separation on silica gel with toluene - acetone 9:1 after pre-washing with methanol. Quantitative determination by absorbance measurement at 250 nm. Guggulsterone E and Z showed Rf values of 0.38 and 0.46 respectively. The proposed method allows separation of the drug from its degradation products and hence is suitable for stability studies.
Chinese J. Trad. Patent Med. (Zhongchengyao) 26 (4), Appendix 2-5 (2004). TLC of Lidan capsule extracts on silica gel with 1) ethyl acetate - butanone - formic acid - water 5:3:1:1; 2) chloroform - methanol - water 30:10:1; 3) petroleum ether (60-90 ºC) - ethyl acetate - benzene 14:3:3; 4) n-hexane - chloroform - methanol 15:8:2. Detection 1) by spraying with 1 % FeCI3 in ethanol; 2) by spraying with a solution of P-dimethylaminobenzaldehyde - ethanol - H2SO4 1:100:10; 3) by spraying with 5 % vanillin - H2SO4 solution followed by heating; 4) by exposing to iodine vapor. Identification by fingerprint technique. Quantification of emodin and chrysophanol by HPLC.
Indian Drugs 41 (6), 362-365 (2004). HPTLC on silica gel with n-butane - n-propanol - glacial acetic acid - water - chloroform 4:1:1:1:2 with addition of formic acid in proportion of 1:0.001. Densitometric evaluation of ginkgo biloba extract by absorbance measurement at 254 nm. The same plate was used for the quantitative determination of ginseng at 520 nm after spraying with ninhydrin reagent. A simple, fast and precise HPTLC method has been developed for the simultaneous determination of ginkgo biloba and ginseng in solid dosage form.
J. Planar Chromatogr. 17, 297-299 (2004). TLC of dopamine, epinephrine, norepinephrine, serotonin and their metabolites metanephrine, normetanephrine, 3,4-dihydroxyphenylacetic acid, vanillylmandelic acid, homovanillic acid, 5-hydroxyindoleacetic acid, 3,4-dihydroxyphenylglycol, 3-methoxy-4-hydroxyphenylglycol, and 3-methoxytyramine on silica gel with citrate buffer (pH 2.00, 3.00, 4.00, and 5.00) - methanol in the proportions 19:1, 9:1, 4:1, 7:3, and 3:2. Examination under UV light at 254 nm and under daylight.
J. Chinese Pharm. Anal. 25 (1), 86-90 (2005). TLC of fructose, fructose-6-phosphate and related impurities on silica gel - carboxy methyl cellulose(CMC) -Na phase with n-butanol - acetone - glacial acetic acid - ammonia - water 35:15:20:3:27. Detection by spraying with 1 % sodium periodate solution followed by spraying with a solution of benzidine - ethanol - acetone - hydrochloric acid - water 0.8 g:80 mL:30 mL:1.5 mL:70 mL. Identification by fingerprint technique. Quantification by comparison with standards. The detection limits were investigated. In addition, the content of magnesium fructose diphosphate was determined by diphenylamine colorimetric method, and the related impurities are determined with the phospho-molybdic acid colorimetric method.
Chinese J. Trad. Pat. Med. (Zhongchengyao) 26 (9), app.19-20 (2004). HPTLC on silica gel with petroleum ether (30 - 60 ºC) - formic acetate - formic acid 15:5:1, at 11 ºC and humidity of 40 %. Detection by exposing to ammonia vapors. Identification by fingerprint technique and comparison with the standards.
Koch ex DC. J. Planar Chromatogr. 18, 224-227 (2005). Analytical and preparative TLC of esculin, umbelliferone, bergapten, xanthotoxin, isoimperatorin, imperatorin, psoralen, cis-kellactone, pteryxin, and epoxypteryxin from Peucedanum verticillare extracts on silica gel with n-heptane - dichloromethane - ethyl acetate 4:5:10 and 3:4:3, and n-heptane - diisopropyl ether - isopropanol 32:8:5 in horizontal chambers after pre-conditioning for 10 min. Detection under UV light at 366 nm.
J. Planar Chromatogr. 18, 455-459 (2005). HPTLC of erythromycin, troleandomycin (oleandomycin triacetate), tylosin, rifamycin B, and rifampicin on silica gel and on RP-18 in a presaturated chamber with wide-ranging mixtures containing 0 to 100 % esters or ketones in dimethyl sulfoxide or hexamethyldisiloxane. Detection by spraying with a mixture of concentrated sulfuric acid and methanol 1:4 followed by heating at 120 °C for 10 min. Chromatographic retention data and a possible retention mechanism are discussed.
