J. AOAC Int. 88, 1555-1561 (2005). HPTLC of chloramphenicol on silica gel in a horizontal developing chamber (36 applications per plate) using n-hexane -ethyl acetate 7:13. Quantitative determination by absorbance measurement at 280 nm. Mean recovery was 95.8 %, and the coefficient of variation was 5.8 %. The detection limit was 3 ng, and the quantitation limit 10 ng.
J. Chromatogr. B 877 (29), 3719-3723 (2009). HPTLC of gemifloxacin mesylate in human plasma, extracted with chloroform - acetic acid 59:1, on silica gel with ethyl acetate – methanol - ammonia 8:4:3. The hRf value of gemifloxacin mesylate was 33. Quantification by densitometry at 254 nm. The calibration curve was established in the range of 50 to 600 ng/spot. Recovery of gemifloxacin mesylate was between 80.0 and 86.2 %. The stability of gemifloxacin mesylate in plasma was confirmed with samples submitted to three cycles of freeze–thawing at -20 °C, and with samples stored on the bench for 12 h.
J. Planar Chromatogr. 24, 520-523 (2011). HPTLC of streptomycin and amoxicillin, ampicillin, cefixime, cephalexin, cloxacillin, co-trimoxazole, doxycycline, erythromycin, gentamycin, metronidazole, tetracycline on titanium(IV) silicate coated plates with 0.5 M potassium bromide and ethanol 9:1 in a twin-trough chamber. Detection by spraying with a fresh 2 % solution of sodium carbonate and 5 % sodium nitroprusside dihydrate in 1 % acetaldehyde 1:1 or iodine solution (2 g iodine and 3 g potassium iodide in 100 mL water). Quantitative determination by densitometry in absorbance mode at 359 nm. The recovery was 97.9 %. LOD and LOQ were 2 and 12 ng/zone, respectively.
CBS 112, 2-4 (2014). TLC and HPTLC of chamomile (Matricaria recutita L.) flowers and standards herniarin, umbelliferone, alpha-bisabolol, and spiroethers on silica gel with chloroform - acetone 99:1 or dichloromethane up to 90 mm (TLC) and 75 mm (HPTLC). Detection under UV 254 and 366 nm and after dipping in vanillin reagent (0.4 % ethanolic vanillin solution with 2 % sulfuric acid) or DPPH radical reagent (0.02 % methanolic 2,2-diphenyl-1-picrylhydrazyl) for information on radical scavenging activity. Biological detection by dipping individually in a suspension of Bacillus subtilis, Aliivibrio fischeri, Pseudomonas syringae pv. maculicola and Xanthomonas vesicatoria. The essential oil component chamazulene showed the strongest antioxidative capacity.
J. Liq. Chromatogr. Relat. Technol. 39, 281-285 (2016). HPTLC bioautography of Potentilla species on silica gel with diethyl ether – methanol – formic acid 150:50:5:1. Direct bioautography by dipping into a bacterial suspension of Bacillus subtilis for 8 s, following incubation at 37 °C for 17 h. Visualization by spraying with 0.2 % MTT (thiazolyl blue tetrazolium bromide) aqueous solution, followed by incubation at 37 °C for 0.5 h.
root extract via HPTLC–UV/Vis/FLD–EDA–MS. J. Planar Chromatogr. 31, 79-86 (2018). HPTLC with effect-directed analysis (EDA) for (bio)profiling of Pimpinella saxifraga root. HPTLC on silica gel with 1) ethyl acetate – methanol – acetic acid 8:3:1 for polar separation, and 2) toluene – ethyl acetate – acetic acid 20:5:1 for apolar separation. Ten different detections were shown on one HPTLC plate cut into sections. Detection of absorbing compounds under A) white light and B) UV 254 nm and C) fluorescent ones under UV 366 nm. Three plate sections were used for microchemical derivatizations for D) detection of flavonoids after derivatization with diphenylborinic acid 2-aminoethylester reagent, followed by dipping into a polyethylene glycol 400 solution, E) universal detection with anisaldehyde sulfuric acid reagent, and F) detection of glycosides with diphenylamine aniline reagent. Effect-directed detection of G) DPPH scavenging compounds, antimicrobials via H) A. fischeri and I) B. subtilis bioassays, and J) AChE inhibitory compounds was also performed. Multi-detection showed multi-potent zones with hRF values of 19, 24, 49 and 78, which were exemplarily further characterized by HPTLC–ESI–MS in both ionization modes. A weak estrogen-effective zone was also observed via HPTLC–planar yeast estrogen screen (pYES) bioassay on RP-18 with n-hexane – toluene – ethyl acetate 6:3:4 or, after optimization, toluene – ethyl acetate 1:1.
J.A.O.A.C. 67, 563-565 (1984). TLC of chloramphenicol on silica with ethyl acetate. Detection: 2 minutes exposure in jar containing solid calcium hypochlorite, 45 sec. in jar containing 37 % formaldehyde, spray lightly with aq. solution containing 1 % starch + 1 % KI. Detection limit: > 60 ng.
J. Agric. Food Chem. 34, 274-276 (1986). TLC of monensin A sodium salt on silica with carbon tetrachloride - benzene - methyl cellosolve 8:1:1 as eluent. Quantitation after removal and extraction with FAB-MS; in addition semiquantitative determination using a TL bioantographic assay (DONOHA & KLINE, Antimicrob. agents, Chemother. 1968, 763-766) with very good agreement between both methods.
