Detection by spraying with 5% sulfuric acid in methanol and heating at 110°C. Identification by retention factors. Preparative TLC of shark liver oil lipids using the same system. SFC of the TLC fractions after elution.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 18, 390-393 (1998). TLC of the methyl esterification products on silica with petroleum ether - ether- acetic acid 35:15:1. Detection by exposure to iodine vapor. Evaluation of the completeness of esterification by finger print techniques. Quantitation by GC.
Part 1: Description of the method and basic possibilities. J. Planar Chromatogr. 15, 454-457 (2002). HPTLC and TLC of a test dye mixture on silica gel in a special horizontal chromatographic chamber. Detection with a new TLC/HPTLC scanner with optical fibers, a special fiber interface, and a diode-array detector working in the range of 197 to 800 nm with an average optical resolution better than 2.0 nm. Description of a novel liquid chromatographic technique, fully on-line TLC/HPTLC. The method integrates the idea of the continuous development, continuous-flow TLC, and diode-array detection. The principle of the method, the design of the prototype apparatus, and the fundamental advantages of the novel technique are described.
J. Chinese Trad. Patent Med. (Zhongchengyao) 11, 885-887 (2004). TLC on silica gel with 1) n-butanol - 3 M NH4OH - ethanol 5:2:1, 2) toluene - ethyl acetate - formic acid 5:4:1. Detection 1) under UV 254 nm, 2) by spraying with 10 % FeCI3 in ethanol. Identification by fingerprint techniques. Quantitative determination of quercetin by HPLC.
LC-GC Europe 18, 482-488 (2005). Contact Bioautography: Antimicrobials diffusion from a TLC plate to an inoculated agar plate.The chromatogram is placed face down onto the inoculated agar layer and left for some minutes or hours for diffusion. After removing the plate the inhibition zones are observed on the agar surface in the places where the spots of antimicrobials are stuck to the agar. The method resembles a disk assay. Immersion Bioautography: The chromatogram is covered with a molten, seeded agar medium. After solidification, incubation and staining (usually with tetrazolium dye) the inhibition or growth bands are visualized. Direct Bioautography: A developed plate is dipped in the suspension of microorganisms growing in a suitable broth or this suspension is sprayed onto the plate. The plate is incubated and microorganisms grow directly on it. It can be performed with Photobacterium phosphoreum (Vibrio fischeri) suspension. Bioautography systems and coupling possibilities are presented.
Anal. Chem. 81, 10275-10284 (2009). Direct quantitative bioanalysis of drugs from dried blood spot samples using a TLC-MS interface with or without HPLC separation. The method gave acceptable sensitivity, linearity, accuracy, and precision data for bioanalytical validations. The direct elution technique was shown to increase assay sensitivity for a range of analytes. Investigations were performed to optimize extraction time, minimize sample-to-sample carry-over, and compare chromatographic performance. On the basis of this preliminary assessment, it has been demonstrated that this TLC-MS interface has the potential to be an effective tool for the direct analysis of drugs in dried blood samples at physiologically relevant concentrations.
CBS 105, 2-4 (2010). TLC and HPTLC of reaction samples from small molecule lead development, on silica gel with mixtures of methanol and dichloromethane/ethyl acetate or ethyl acetate and heptane/cyclohexane (ratios depending on the compound mixtures). Detection with primuline or berberine reagent. Direct elution into the MS with the TLC-MS interface. Substances not detected by DAD can successfully be measured by ELSD detection coupled to TLC.
J. AOAC Int. 96, 1209-1213 (2013). TLC of thujone (1) and 1,8-cineole (2) in the leaves of Artemisia adamsii essential oil on silica gel with toluene - ethyl acetate 93:7. Detection by dipping into vanillin - sulfuric acid reagent, followed by heating at 90 ºC for 3 min. The hRf values for (1) and (2) were 56 and 45. Bioautography by dipping into S. aureus suspension for 10 s. After drying for 2 min followed by incubation at 37 ºC for 17 h the plates were dipped in an aqueous solution of MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide 50 mg/80 mL) for 10 s and incubated at 37°C for 2 h. Inhibition zones appeared as pale yellowish zones against blue background.
