J. Planar Chromatogr. 25, 89-90 (2012). TLC of sample solutions from a horizontal rotating tubular bioreactor on cellulose-coated TLC plates. Detection of metal ions by spraying with solutions of quercetine (0.1 g/100 mL 2-propanol) and dimethylglyoxime (1.0 g/100 mL ethanol), and exposure to ammonia vapor. Linearity was found to be in the range of 0.05-1.0 g/L.
J. Chinese Med. 25 (151), 1134-1135 (2010). Yankening tablet, specially effective for diminishing inflammation, is a herbal TCM preparation with Rheum officinale as key component drug. However, some counterfeits are used to replace the certified products, thus abating seriously the curative effect of the medicine. To control the quality of the medicine a method has been presented for inspection of rhaponiticin in Yankening tablets. TLC of the extracts of the medicine on silica gel with ethyl acetate – butanone – formic acid – water 10:7:1:1, detection under UV 366 nm. Identification 1) by fingerprint comparison with the standard rhaponiticin; 2) by comparing the online scanning spectra over the wavelength range from 200 – 700 nm.
J. Planar Chromatogr. 25, 456-462 (2012). HPTLC of loratadine (1) and desloratadine (2) on silica gel with methanol + 1 drop ammonia. Quantitative determination by absorbance measurement at 254 nm. The hRf values of (1) and (2) were 76 and 20, respectively. Linearity was in the range of 250-850 ng/band for (1) and 100-1000 ng/band for (2). Limits of detection and quantification were 90 and 250 µg/band for (1) and 30 and 100 µg/band for (2), respectively. Intra- and inter-day precisions were found to be less than 2 %. Recoveries were between 97.8 and 101.5 % for both (1) and (2).
CBS 109, 2-4 (2012). Extraction of arabica coffee with 2 to 50 % robusta coffee by accelerated solvent extraction with tBME. A part was saponified with10 % ethanolic KOH solution for 2 h. HPTLC of coffee extracts and standards 16-O-methylcafestol (16-OMC) and 16-OMC esters on silica gel with toluene - ethyl acetate - acetic acid 93:7:1 for 16-OMC esters and with tBME - chloroform 1:1 for 16-OMC. Detection by spraying with vanillin sulfuric acid (1 g in 250 mL ethanol and 2 mL of sulfuric acid, prepared freshly) and heating for 1 min at 80 °C. Quantitative absorption measurement at 530 nm. The LOD was 163 ng/band. After saponification the LOD of free 16-OMC was 43 ng/band. Thus 2 % robusta can be detected in a coffee blend.
Food Chemistry. 139, 866-871 (2013). HPTLC of catechin (1), proanthocyanidin (PAC) A2 (2) and PAC-B1 (3) in American cranberry (Vaccinium macrocarpon) extracts on silica gel with dichloromethane - ethyl acetate - formic acid 6:10:1. Detection by dipping into a hydrochloric solution of 1 % (w/v) vanillin, followed by heating at 110 °C for 2 min. Quantitative determination by absorbance measurement at 254 and 366 nm. The hRf values of (1), (2) and (3) were 63, 48 and 25, respectively. Linearity was in the range of 0.6-5 µg/band. Intermediate precision was below 2.1 %. Average recoveries (by standard addition) were 98.4 % for (1), 99.6 % for (2) and 98.5 % for (3).
J. of Inner Mongolia Univ. for Nationalities (Natural Sci. Edit.) 27 (1), 80-83 (2012). Yuzan Qingyan Shiwuwei pills are a traditional Mongolian herbal medicine for treating colds, sore throat, asthma, cough, etc. For quality control, TLC on silica gel 1) for Fructus Gardeniae and the standard gardenoside, with ethyl acetate – acetone – formic acid – water 5:5:1:1, detection by spraying with 10 % sulfuric acid in ethanol and heating at 105 °C, viewing in daylight; 2) for Radix Aucklandiae and the standards costunolide and dehydrocostus lactone, with cyclohexane – formic acetate – formic acid 15:5:1, detection by spraying with 1 % vanillin in sulfuric acid – ethanol 1:200 and heating mildly, viewing in daylight; 3) for Radix Glycyrrhizae and the standard glycyrrhetinic acid, with benzene – petroleum ether (30-60 °C) – ethyl acetate – glacial acetic acid 50:25:20:3, detection under UV 366 nm.
J. of Qilu Med. & Pharm. 31 (6), 339-340 (2012). Yinxie Granules are a herbal TCM for treating difficult skin diseases, like psoriasis, etc. For quality control, identification of Smilax china L. by TLC on silica gel with chloroform – ethyl acetate – methanol – water 3:8:3:2, detection under UV 366 nm. Quantification of astilbin by HPLC.
J. Planar Chromatogr. 25, 23-29 (2012). HPTLC of nicotine in tobacco extracts on silica gel with ethyl acetate - methanol - ammonia 28 % 10:5:2. Quantitative determination by absorbance measurement at 263 nm. The hRf of nicotine was 20. Linearity was in the range of 90-900 ng/zone. The intermediate/inter-day/intra-day precision was below 2 %.
