Abstract

Three methods of coupling development and elution were studied in this paper. (1) A new mode of solvent supplementation and eluate collection was developed for descending development. By using a new distributor and collector in descending development, components can be separated and eluted continuously. (2) The same effect can be realized with a slope distributor [Su et al., J. Planar Chromatogr. 14 (2001) 203] and a collector by horizontal development. (3) In-situ elution can be used to treat a developed silica plate, which can elute the separated components to the receptor without scraping them off. These three methods can be used individually, and the in-situ elution can be used with other modes of development.

Monolithic porous polymer layer for the separation of peptides and proteins using thin-layer chromatography coupled with MALDI-TOF-MS.

Plates for thin-layer chromatography (TLC) with an attached layer of porous polymer monolith have been prepared and used for the separation of small molecules, peptides, and proteins. The 50-200-mum. thin poly(butyl methacrylate-co-ethylene dimethacrylate) layers were prepared in situ using UV-initiated polymerization. Precise control of the reaction conditions enables the preparation of monolithic layers with a well-defined porous structure that determines the chromatographic performance. Compared to conventional TLC and high-performance TLC using precoated layers based on silica, the small layer thickness and absence of any binder is expected to improve both retention characteristics and separation efficiency of the polymer-based monolithic thin-layer chromatographic plates. Spots of the separated compounds were first detected using typical UV imaging. Since the monolithic thin layers can be also prepared directly on the stainless steel MALDI carrier plate, the separation in TLC format can be coupled with MALDI-TOF-MS. Application of a conventional MALDI matrix facilitated desorption and ionization of peptides and proteins for molecular weight determination of the separated compounds.

Separation of solanesol in tobacco leaves extract by slow rotary counter-current chromatography using a novel non-aqueous two-phase solvent system.

Non-aqueous solvent system composed of sunflower oil-ethanol was found to be suitable for the separation of lower polarity components. Employing this solvent system, 3 g of tobacco leaves extract containing 15% solanesol was separated using a slow rotary counter-current chromatograph equipped with an 1100 mL column made of 5.7 mm I.D. convoluted PTFE tube. The separation yielded 1.5 g of yellow oily product in which solanesol occupied 26.8% determined by HPLC. The tobacco tar and other main impurities in the tobacco leaves extract were removed after slow rotary counter-current chromatographic separation. The separation processing may be developed as a technique for producing a solanesol product with food grade.

Selective thin-layer chromatography of 4-R-1,2,4-triazoles.

A convenient and selective TLC of 4-R-1,2,4-triazoles (Rtrz) and nitrogen containing aromatic rings is presented (molecules 1-11). This simple revelation method implies a complexation of heterocycles to Co(II) ions on a TLC plate, followed by a subsequent modification of the reduction potential which enables oxidation of Co(II) by permanganate.
