J. Planar Chromatogr. 27, 274-290 (2014). TLC of saffron in Crocus sativus on silica gel with n-butanol - acetic acid - water 4:1:1. Quantitative determination by image analysis which produced intensity profiles based on red, green and blue characteristics (RGB) and further processing by specially designed software. The method allowed for comparison of different types of saffron (geographical differentiation and discrimination of natural and adulterated samples) using hRf values, color range and intensity of the separated components.

Trends in Chromatography 8, 131-135 (2013). Based on the Minilab TLC screening methods two individual and one simultaneous HPTLC methods for quantification of lumefantrine and artemether were developed. HPTLC of artemether, lumefantrine, and both substances in a combined tablet formulation on silica gel with ethyl acetate - glacial acetic acid - toluene 2:1:9 with chamber saturation. Quantitative absorbance measurement of lumefantrine at 254 nm. For artemether, detection by spraying with methanol - 96 % sulfuric acid 19:1 and heating at 100 °C for 5 minutes, evaluation in daylight and quantitative absorbance measurement at 610 nm. With the simultaneous method artemether zones were detected by heating at 160 °C for 5 min, and after cooling absorbance measurement at 254 nm was performed. This is a novel, reagent-free detection method based on thermochemical activation of fluorescence quenching. Precision (%RSD) for the artemether individual method was 0.1-0.6 % and recovery 98-103 %. Precision (%RSD) for the lumefantrine individual method was 0.9-1.8 % and recovery 100-102 %. With the simultaneous method the hRF was 34 for lumefantrine and 61 for artemether, precision (%RSD) was below 3 % and recovery was 98-100 %.

For quality control, TLC on silica gel 1) for Lonicera japonica Thunb. and the standard chlorogenic acid, with formic acid - ethyl acetate – water 5:14:5, detection under UV 366 nm; 2) for Paeonia suffruticosa Andr. and the standard paeonol, with cyclohexane - ethyl acetate 3:1, detection by spraying with the acidic solution of 5 % ferric chloride in ethanol and heating mildly until the zones are visible in daylight; 3) for Carthamus tinctorius L., with ethyl acetate – formic acid – water – methanol 35:10:15:2, detection in daylight. Quantification of berberine hydrochloride by HPLC.

China Pharm. 22 (20), 21-23 (2013). Clematis L. is a traditional mongolian medicines. HPTLC identification of C. aethusifolia, C. intricate, C. brevicaudata, C. hexapeta, C. macropetala and C. mandshurica on silica gel with (A) petroleum ether (60-90°C) – ethyl acetate – acetone 9:3:1 at 25 °C and relative humidity of 50 %, detection by spraying with sulfuric acid – water 1:3, followed by heating at 100 °C until the spots were visible, or (B) chloroform – methanol – water 30:6:1 at 25 °C and relative humidity of 50 %, detection by spraying with sulfuric acid – water 1:3, followed by heating to 100 °C and viewing at UV 366 nm.

Yinchen Siling Keli granule is a TCM preparation for the treatment of chronic active hepatitis B and liver cirrhosis, etc. For quality control, TLC on silica gel (1) for Artemisia capillaris Thunb. with petroleum ether (60-90 ˚C) – ethyl acetate – acetone 5:3:2, detection by spraying with 5 % KOH solution and evaluation under UV 366 nm; (2) for Rheum officinale Baill. and the standards emodin, rhein, and chrysophanol, with the upper phase of petroleum ether (60-90 ˚C) – ethyl formate – formic acid 15:5:1, detection under UV 366 nm. Quantitative determination of paeoniflorin, gardenoside, emodin, and chrysophanol by HPLC.

Journal of Ethnopharmacology 163, 192-202 (2015). TLC of the aqueous extract (crude vs. after tannin removal on a polyamide column) of the kino (red hydrosoluble exudate) of Pterocarpus erinaceus on silica gel with s-butanol – water – acetic acid 14:5:5. Detection with vanillin-hydrochloric acid reagent revealed catechic tannins and related polyphenols as dark pink zones. These compounds showed hRfs between 0 and 40, and above 60 in the case of the crude extract, whereas they almost did not appear in the tannin-free fraction. The extracts were also submitted to HPLC-HRMS, allowing the identification of epicatechin monomer in both extracts and of oligomers in the crude extract only.
