J. Planar Chromatogr. 27, 107-112 (2014). HPTLC of disulfiram on RP-18 with methanol - water 9:1. Detection by spraying with copper(II) sulfate (0.5 mol/L), followed by heating at 50 ºC for 2 min. Quantitative evaluation with an office scanner at 300 dpi followed by image processing with software. The hRf value for disulfiram was 67. Linearity was in the range of 1-10 μg/zone. The intermediate/interday/intra-day precisions were below 1 % (n=6). The LOD and LOQ were 260 and 860 ng/zone, respectively. Recovery was in the range of 92.4-102.0 %.
J. Planar Chromatogr. 27, 5-10 (2014). _x000D_HPTLC of magnolol (1) and konokiol (2) in the cortex of Magnoliae officinalis on silica gel with toluene - methanol 10:1. Detection by dipping into 2,2-diphenyl-1-picrylhydrazyl radical reagent (DPPH) in ethanol (1 g/L) for 40 min. Quantitative determination by absorbance measurement at 550 nm. Linearity was in the range of 160-960 ng/zone for (1) and 162-977 ng/zone for (2). The intermediate/interday/intra-day precisions were below 2 % (n=6). The LOD and LOQ were 40 and 149 ng for (1) and 32 and 85 ng for (2), respectively. Recovery was in the range of 94.5-105.9 % for (1) and 86.6-103.4 % for (2). The HPTLC-DPPH method showed comparable results to an HPLC method._x000D_
J. of China Pharm. 27 (7), 722-724 (2013). Xihuang Wan pill is a herbal TCM prescribed for treatment and adjuvant therapy of various cancers. Huoxue Zhitong San powder is a herbal TCM prescribed for traumatic injury and ecchymoma. In the drug market fraud rosin was found to be added to the key ingredient olibanum. For quality control, HPTLC of the sample extracts and the standards acetyl-11-keto-beta-boswellic acid (AKBA), 11-keto-beta-boswellic acid (KBA), beta-boswellic acid (beta-BA), acetyl-beta-boswellic acid (beta-ABA), and abietic acid (LOD=1.0 µg), on silica gel with toluene – ethyl acetate – heptane – formic acid 80:20:10:3 with chamber saturation for 20 min, detection 1) under UV 254 nm and UV 366 nm; 2) by spraying with a fresh solution of anisaldehyde – sulfuric acid – acetic acid 1:10:1000 and heating at 105 °C until the zones were visible in daylight. Verification of abietic acid from added rosin by HPLC. The method was used for the analysis of 63 batches of Xihuang Wan pills sampled from 13 pharmaceutical factories and 10 batches of Huoxue Zhitong San powder from 4 factories.
J. Planar Chromatogr. 27, 420-427 (2014). HPTLC and TLC of fatty acids and polyphenols in plant extracts of raspberry (Rubus idaeus), strawberry (Fragaria ananassa), blackcurrant (Ribes nigrum), aronia (Aronia Medik.), Japanese rose (Rosa rugosa Thunb.) seeds, and palmetto palm (Sabal minor) fruit on silica gel or RP-18 with different micellar mobile phases containing cationic cetyltrimethylammonium bromide (CTBA), or anionic sodium dodecyl sulfate (SDS), or nonionic polioxyethylene (23) lauryl ether (Brij35).

Food Res. Int. 65, 13-19 (2014). Review of the challenges and limitations in the analysis of polyphenol-protein interactions. The author described some properties of the HPTLC, such as the level of resolution that can be obtained with 2D-HPTLC and the coupling with mass spectrometry, that make this tool a promising alternative for the analysis of protein-phenol adducts.
