J. Chromatogr. A 787, 227-233 (1997). Examination of the influence of temperature and mobile phase composition on retention of a-, b-, and g-cyclodextrins and two macrocyclic antibiotics. Measurement of RF values of the solutes at temperature from 5 to 60°C. Estimation of the change of enthalpy (DH°) and entropy (DS°) from linear Van't Hoff plots. Discussion of temperature as useful parameter for designing an enantioselective chromatographic system in which Rf values of the chiral phases modifier should be equal to 0 or 1.

Information on the range of linearity, sensitivity of detection, relative standard deviation, and recovery is given.

J. Planar Chromatogr. 17, 84-88 (2004). OPLC of trans-resveratrol on silica gel with chloroform - methanol 10:1 after preconditioning of the plates for 3 h at 120 °C. Detection by immersion of the dried plates in a bacterial suspension (Pseudomonas savastanoi pv. phaseolicola race 6) for 20 s and MTT staining (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide; 80 mg MTT and 100 mg Triton X-100 in 100 mL water) either after a short draining period or after overnight incubation; after staining the time for evaluation varied (e. g. from 1 h to 6 - 9 days or more). First results of the investigation of a complex bioautographic system with special emphasis on the direct effect of the antibiotic trans-resveratrol (fitoalexin) and the function of formaldehyde in relation to antibiotics.

Food Control. 34, 138-148 (2013). TLC was reviewed as a fast screening methodology for the determination of deoxynivalenol (DON) showing LOD in rice of 100 mg/kg. 2D-TLC on silica gel with dichloromethane - ethyl acetate - propan-2-ol 18:1:1 and toluene - ethyl acetate - formic acid 6:3:1 for the first and second runs, respectively. Detection by spraying with chromotropic acid, followed by heating at 110 °C for 5 min. Quantitative determination by absorbance measurement at 366 nm. The hRf values of DON were 13 and 20. Advantages and disadvantages of current methods as well as comparison with other techniques were also described for the effective monitoring and surveillance of DON and its derivatives.

Budapest Chromatography Symposium, June 13, 1985. Two-dimensional TLC on silica with 1) isopropanol - water - NH3 3:2:1, 2) isopropanol - water - triethylamine 3:2:1. Detection with orcinol-ferrichloride-sulfuric acid reagent. Partial hydrolysis of endotoxins with mild acids cleaves off non-toxic but beneficially active fragments. Fractionation of these components by TLC combined with high-voltage electrophoresis. In the first dimension TLC with isopropanol - acetic acid - water 5:1:5, followed by electrophoresis in pyridine - acetic acid - water 6:5:90 buffer.
