Phytochem. Anal. 26, 404-412 (2015). TLC-autography of physostigmine in an extract of Brassica rapa with the acetylcholinesterase inhibitor on a TLC plate sprayed with a solution of α-naphthyl acetate (2.5 mg/mL) – fast blue B (2.5 mg/mL) 4:1 and with a acetylcholinesterase agar solution distributed over the TLC plate. The plate was developed with dichloromethane - methanol 9:1, ethyl acetate - methanol - water 5:5:2 and toluene - chloroform - ethanol 57:114:29. Further extraction and analysis with high resolution mass spectrometry. _x000D_

J. Planar Chromatogr. 29, 108-112 (2016). HPTLC of water-soluble vitamins (B1, B2, B6, C, and B12), amino acids and β-blocker enantiomers (carvedilol, (S)-(−)-propranolol hydrochloride, (±)-propranolol hydrochloride, and (±)-sotalol hydrochloride) on novel core–shell polymers consisting of hyperbranched (poly(ethyleneimine)) core surrounded by oligosaccharide shell (PEI-OS) as a component of the silica gel phase. The influence of the weight of the hyperbranched PEI core (5 and 25 kDa) was investigated. β-blocker enantiomers were separated using acetonitrile - methanol 7:3. PEI-maltose and PEI-lactose were the most effective polymers for the chiral separation of β-blockers.

Planta Medica 82, 09/10, 903-909 (2016). To monitor the sorbent phase purification of a chloroform subfraction of the sponge Myxilla incrustans, TLC of fractions on silica gel with dichloromethane – methanol – formic acid 900:100:1, detection with Dragendorff’s reagent. The four positive fractions were purified by preparative HPLC, yielding three new N-acyl dopamine/dehydrotyrosine glycosides: myxillins A, B and C._x000D_

J. Planar Chromatogr. 29, 229-231 (2016). HPTLC of imipenem, meropenem, doripenem and eratapenem on silica gel G with 11 developing systems. Detection by spraying with iodine solution (0.2 g of potassium iodine and 0.4 g of iodine_x000D_ mixed in 20 mL of ethanol and 5 mL of hydrochloric acid), ninhydrin reagent (0.1 % ninhydrin in ethanol) or potassium permanganate solution (1 mg dissolved in 10 mL of water). The hRF values for the studied carbapenems in each developing system ranged between 13 and 58.

Chinese J. Hosp. Pharm. 35 (11), 992-996 (2015). Sisheng Keli granule is a herbal TCM preparation for treating hematemesis, hematuria, allergic purpura and thrombocytopenic purpura, etc. For quality control, TLC on silica gel (1) for Artemisia argyi Levl. et Vant., with petroleum ether (60-90 °C) – toluene – acetone 20:16:1, detection by spraying with 1 % vanillin in sulfuric acid – ethanol 1:4 and heating at 105 °C until the zones are visible; (2) for Platycladus orientalis (L.) Franco, with toluene – ethyl acetate – formic acid 5:2:1, detection by spraying with 1 % aluminium trichloride in ethanol and detection under UV 366 nm; (3) for Lotus leaf, with chloroform – acetone – 10 % ammonia in ethanol 60:20:1, detection by spraying with 5 % potassium bismuthate solution and heating at 105 °C until the zones are visible. Quantification of nuciferin and verbascoside by HPLC.

J. Ethnopharmacol. 192, 283-291 (2016). Ubtan is a traditional herbal formulation in the Indian system of medicine, prepared by mixing powdered turmeric (Curcuma longa L.), chickpea (Cicer arietinum L.) and sandal wood (Santalum album L.). HPTLC of four in-house formulations of Ubtan (UF-1, UF-2, UF-3 and UF-4, prepared with varying quantities of each ingredient) on silica gel with cyclohexane – ethyl acetate – formic acid 90:9:1. Detection by spraying with p-anisaldehyde sulfuric acid reagent, followed by drying at 40 ºC for 10 min. The hRF values for UF-1 were 70 and 42.

Ander in rats. J. Ethnopharmacol. 194, 947-953 (2016). HPTLC of alkaloid (1) and (2) in the whole plants of Hygrophila spinosa on silica gel with hexane – dichloromethane – methanol 5:90:8. Detection by spraying with Dragendorff's reagent and drying at room temperature. Qualitative identification at 520 nm. The hRF values for (1) and (2) were 48 and 56, respectively.

J. Chromatogr. Sci. 54 (1), 70-78 (2016). HPTLC of flurbiprofen and chloramphenicol in the presence of their degradation products, produced in acidic, alkaline, neutral, oxidative, photolytic and thermal stress conditions, on silica gel with ethyl acetate – n-hexane – methanol – triethylamine 10:8:4:1. The hRf of flurbiprofen was 29 and of chloramphenicol 62. Quantitative determination by densitometry at 267 nm. Linearity was between 12 and 60 ng/zone with a correlation coefficient of 0.9997 for flurbiprofen and between 200 and 1000 ng/zone with a correlation coefficient of 0.9977 for chloramphenicol. The application of the method to the estimation of flurbiprofen and chloramphenicol in commercial ophthalmic formulation indicated that the method was specific, accurate, reproducible and suitable for routine analysis of flurbiprofen and chloramphenicol in the presence of their degradation products in their individual as well as combined pharmaceutical formulations.
