CBS 113, 13-15 (2014). HPTLC of glycosylceramide Glc-d18:2 h16:0 from wheat germ and standards squalene, cholesteryl oleate, glyceryl trioleate, linoleic acid, ß-sitosterol, and ß-sitosterol glucoside on silica gel in the AMD 2 with a 18-step gradient modified from Opitz et al. (Chromatographia 73 (2011) 559), methanol replaced ethanol, and the mobile phase composition was changed slightly (pre-conditioning with 4 M acetic acid before each step, drying time 1.5 min, development duration 3 h and solvent consumption 200 mL). Detection by dipping in copper sulfate phosphoric acid reagent for 20 s and heating at 130 °C for 15 min revealed grey-brown bands. Densitometry evaluation by absorbance measurement at 546 nm. For Glc-d18:2 h16:0, regression analysis showed a polynomial relationship with coefficients of determination (R2) from 0.995 to 0.999 (n=3, 50 - 1000 ng/band). LOD (S/N 3) and LOQ (S/N 10) of Glc-d18:2_x000D_ h16:0 were 10 ng/band and 50 ng/band, respectively (n = 6).
J. Planar Chromatogr. 29, 273-280 (2016). HPTLC of piroxicam, tenoxicam, meloxicam and isoxicam on silica gel with ethyl acetate – toluene – butylamine 2:2:1. Detection under UV 290 nm. The method was applied to study the effect of oxidizing or reducing agents on the stability of these drugs.
J. Planar Chromatogr. 29, 176-183 (2016). HPTLC of atracurium besylate (1) and atropine sulfate (2) on silica gel with acetonitrile – methanol – dichloromethane – glacial acetic acid – water containing 70 mg L-(+)-tartaric acid 70:10:5:7:1, pH 5 for (1), and methanol – water containing 40 mg L-histidine and 20 mg copper(II) acetate 22:3, pH 7 for (2). Quantitative determination by absorbance measurement at 280 nm for (1) and 215 nm for (2). The hRF values for (1) and (2) were 51 and 65, respectively. Linearity was in the range of 2-14 μg/zone for (1) and 5-35 μg/zone for (2). Intermediate precisions were below 1 %. The LOD and LOQ were 0.5 and 1.6 µg/zone for (1) and 1.2 and 3.6 µg/zone for (2). Average recovery was found to be 103.4 % for (1) and 96.6 % for (2).
J. Ethnopharmacol. 195, 10-19 (2017). HPTLC of mesembrine alkaloids (mesembrine, mesembrenone, mesembrinol, mesembrenol, epimesembranol, epimesembrenol) in the South African medicinal plant Sceletium tortuosum on silica gel with dichloromethane – methanol – 10 % ammonia 900:100:1. Quantitative determination by absorbance measurement at 280 nm. The LOD and LOQ were in the range of 18-31 ng/zone and 44-95 ng/zone, respectively.
J. Planar Chromatogr. 30, 275-284 (2017). HPTLC of selected cosmetic raw materials (UV filters and preservatives) on RP-18 with acetonitrile ‒ pH 7.4 phosphate buffered saline 7:3. Qualitative determination at UV 254 nm. Molecular descriptors were calculated to examine the behavior towards the blood-brain barriers.

J. Planar Chromatogr. 30, 175-180 (2017). HPTLC of β-amyrin (1) and β-sitosterol (2) in the aerial parts of Tinospora cordifolia and Calotropis gigantia on silica gel with n-hexane – ethyl acetate 3:1. Detection by spraying with p-anisaldehyde reagent. Quantitative determination by absorbance measurement at 530 nm. The hRF values for (1) and (2) were 39 and 26, respectively. Linearity was between 100 and 1400 ng/zone for (1) and (2). LOD and LOQ were 18 and 55 ng/zone for (1) and 30 and 91 ng/zone for (2). The intermediate precision was <2 % (n=6). Recovery rate ranged from 98.4 to 99.3 % for (1) and 98.3 to 99.9 % for (2).
