J. Planar Chromatogr. 27, 151-156 (2014). UTLC plates were microfabricated by atomic layer deposition of silica onto patterned carbon nanotubes. The plates X-ray consisted almost entirely of silicon and oxygen without contamination of metals such as aluminum, which would disturb the chromatographic result. The layer thickness was around 50 μm. Separation of a test dye mixture (eosin Y disodium salt and sulforhodamine B) on an uncoated UTLC silica gel plate under normal phase conditions gave efficiencies of 40 000-140 000 plates/m and migration distances between 2-36 mm. UTLC of the same mixture on an amino-modified plate gave efficiencies of 170 000-200 000 plates/m, with hRF values of 76 and 88, respectively. The new ultrathin plates featured a high separation efficiency and shorter development time than conventional TLC/HPTLC plates.
J. Planar Chromatogr. 27, 255-259 (2014). HPTLC of betulin (1) and betulinic acid (2) in Diospyros sylvatica on silica gel with chloroform - methanol - formic acid 46:1:1. Quantitative determination by absorbance measurement at 210 nm. The hRF values for (1) and (2) were 52 and 45, respectively. Linearity was in the range of 400-2200 ng/zone for (1) and (2). The intermediate/interday/intra-day precisions were below 5 % (n=5). The LOD and LOQ were 106 and 352 ng/zone for (1) and 76 and 253 ng/zone for (2), respectively. Average recovery was 95.5 % for (1) and 93.2 % for (2), respectively.
J. Liq. Chromatogr. Relat. Technol. 37, 1524-1534 (2014). HPTLC of haloperidol on RP-18 with acetonitrile - water - 1-alkyl-3-methylimidazolium tetrafluoroborate 120:80:3.

f. J. Planar Chromatogr. 27, 251-254 (2014). HPTLC of arnebin-1 in the roots of Arnebia nobilis on silica gel with toluene - ethyl acetate - formic acid 80:19:1. Quantitative determination by absorbance measurement at 284 nm. The hRF value for arnebin-1 was 65. Linearity was in the range of 2.5-20 μg/zone. The intermediate/interday/intra-day precisions were below 5 % (n=3). The LOD and LOQ were 14 and 48 ng/zone, respectively. Average recovery was 92.0 %.
J. Planar Chromatogr. 27, 186-191 (2014). HPTLC of rutin (1), rosmarinic acid (2), and glycyrrhizin (3) in the medicinal preparation Savda Munziq on silica gel with ethyl acetate - formic acid - acetic acid - water 30:2:2:3. Quantitative determination by absorbance measurement at 250 nm. The hRF values for (1) to (3) were 16, 86 and 9, respectively. Linearity was in the range of 128-2048 ng/zone for (1), 322-5144 ng/zone for (2) and 70-1120 ng/zone for (3), respectively. The intermediate/inter-day/intra-day precisions were below 3 % (n=3). The LOD and LOQ were 37 and 124 ng/zone for (1), 38 and 127 ng/zone for (2) and 33 and 111 ng/zone for (3), respectively. Recovery for (1) to (3) was in the range of 95.4-104.0 %.

J. AOAC Int. 97, 791-797 (2014). HPTLC of (1) atorvastatin calcium and (2) olmesartan medoxomil on silica gel with chloroform – methanol – acetonitrile 2:1:2. Quantitative determination by absorbance measurement at 276 nm. The hRF values of (1) and (2) were 47 and 69, respectively. Linearity was between 300 and 750 ng/zone for (1), and between 600 and 1500 ng/zone for (2). The intermediate inter-day and intra-day precisions were below 1 % (n=9) for both, (1) and (2). The LOD and LOQ were 6.3 and 19.0 ng/zone for (1) and 3.1 and 9.5 ng/zone for (2). Recoveries for (1) and (2) were in the range of 98-102 %. The method showed comparable results to a validated HPLC method and a UV spectrophotometric method.
