J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (3), 279-282 (2005). TLC of the extracts of the title Chinese traditional patent medicine on silica gel with 1) ethyl acetate - methanol - ammonia 17:2:1; 2) n-butanol - glacial acetic acid - water 19:5:5. Detection 1) under UV 365 nm; 2) by spraying with ninhydrin solution followed by heating at 105 ºC until the spots are visualized. Identification by fingerprint technique. Quantification of paracetamol and pseudoephedrine arginine by HPLC.
J. Liq. Chromatogr. Relat. Technol. 28, 2361-2382 (2005). TLC of (-)-delta9-tetrahydrocannabinol, cannabinol, cannabidiol, cannabigerol, (-)-delta9-(trans)-tetrahydrocannabinolic acid A, cannabidioloc acid, and cannabigerolic acid as reference compounds on RP-18 with methanol - 5 % acetic acid 19:1; and on silica gel with chloroform - methanol 19:1. Evaluation under UV 254 nm. Detection by spraying with modified anisaldehyde - sulfuric acid reagent. For selective detection of cannabinoids, plates were sprayed with 0.5 % fast blue B salt in water, followed by spraying with 0.1 M sodium hydroxide solution.
J. Sep. Sci. 30, 2167-2172 (2007). HPTLC of clozapine in human serum on silica gel with chloroform - methanol 9:1. Quantitative determination by absorbance measurement at 290 nm. Linearity was between 10 and 100 ng/zone. The intra-assay variation was between 2.10 and 3.33 % (n=5) and inter-assay variation was between 2.67 and 4.44 % (n=9). The limits of detection and quantification were 0.03 and 0.05 ng/µL, respectively. Recovery was between 97.0 and 99.0 %, and selectivity regarding matrix was given.
J. Pharm. Biomed. Anal. 43 (3), 839-844 (2007). HPTLC of artemether both as a bulk drug and in pharmaceutical formulations on silica gel aluminum plates with toluene - ethyl acetate - formic acid 80:20:3. Quantification of artemether by densitometry at 565 nm. Linearity was between 200 and 1000 ng/spot. The limit of detection and quantification was 65 and 197 ng/spot, respectively. The method was successfully applied in the analysis of lipid based parenteral formulations and marketed oral solid dosage formulation.
Anal. Chim. Acta 598 (2), 312-317 (2007). TLC of paroxetine hydrochloride on silica gel with butanol - acetic acid - water 16:4:1. The hRf value of paroxetine HCl was 48 and separation from the degradation products (produced by acid and alkali hydrolysis, oxidation and photodegradation) was good. Quantitative determination by absorbance measurement at 295 nm. The linearity was in the range of 300 - 1500 ng/spot and the correlation coefficient was 0.9903. The limit of detection and quantitation was 50 and 150 ng/zone, respectively.
J. Chromatogr. Sci. 49, 129-135 (2011). TLC of hydrochlorothiazide (HCT), spironolactone (SPR) and their impurities and degradation products on silica gel with ethyl acetate - chloroform - formic acid - triethyl amine 70:30:1:1. Quantification by densitometry. The different method parameters were optimized for maximum separation. The method was applied for determination of HCT and SPR in commercial tablets. Statistical comparison with the also performed HPLC method showed that there is no significant difference in the performance of the methods.
J.of Jiangxi Univ. of TCM 22 (5), 55-57 (2010). TLC of Shujinhuoxue pills: 1) for Angelica sinensis, on silica gel with cyclohexane – ethyl acetate 12:1, detection under UV 365 nm; 2) for Rheum officinale, on silica gel with petroleum ether (30-60 ºC) – ethyl formate – formic acid 15:5:1, detection by exposure to ammonia vapors; 3) for Radix Rehmanniae praeparata, on silica gel with petroleum ether (60-90 ºC) – ethyl acetate 1:1, detection under UV 254 nm; 4) for Gardenia jasminoides, on silica gel with ethyl acetate – acetone – formic acid – water 5:5:1:1, detection by spraying with 10 % sulfuric acid in ethanol and heating at 110 ºC until the zones were visualized; 5) for Lignum Sappan, on polyamide phase with 36 % acetic acid, detection by spraying with 5 % AlCl3 in ethanol and heating mildly until the spots were visualized.
