J. Chromatogr. A 1145 (1-2), 222-228 (2007). Pre-fractionation of cis and trans-fatty acids by silver-ion TLC (Ag-TLC) and other methods (silver-ion SPE (Ag-SPE) or HPLC) allows accurate determination of the isomeric profile but is not essential to achieve quantification of total trans-18:1 isomers nor to determine the level of vaccenic (trans-11 18:1) acid in dairy fat. Comparison of different GLC methods suitable to measure the total of trans-18:1 isomers, vaccenic acid and trans-18:1 acid isomeric distribution in milk fat. Pre-separation of cis- and trans-18:1 isomers by Ag-TLC followed by GLC analysis under optimal conditions was selected as the reference method.
J. Planar Chromatogr. 20, 429-435 (2007). HPTLC of 3 phenolic acids (caffeic acid, p-coumaric acid, isoferulic acid) and 4 flavonoids (pinocembrin, pinocembrin-7-methyl ether, chrysin, tectochrysin) on silica gel with chloroform - methanol - formic acid 88:7:5 with chamber saturation. Detection by spraying with 1 % ethanolic aluminium chloride solution. Quantification by scanning densitometry in absorbance mode.
Food Chem. 79, 337-342 (2002). HPTLC of polyphenol compounds (caffeic acid derivatives, quercetin and kaempferol glycosides) in the leaves of Lactuca sativa on RP-18 with water – methanol – acetic acid 25:25:3. Detection by dipping into a solution of 1 % ethanolamine diphenylborate in methanol for 24 h. Quantitative determination by absorbance measurement at 365 and 440 nm. The total flavonoid amount is expressed as isoquercitrin using a three point regression curve in the range of 1 and 5000 ng/zone.
J. Liq. Chromatogr. Relat. Technol. 30, 2267-2285 (2007). Analytical and preparative TLC of lipid classes, their fatty acid profiles, and the triacylglycerol and sterol composition on silica gel and modified silica gel (impregnated with silver nitrate for Ag-TLC or dimethyldichlorosilane for RP-TLC). TLC of lipid reference mixture on silica gel with hexane - acetone 25:4. Detection by spraying with 50 % ethanolic sulfuric acid and heating at 200 °C. Preparative TLC for isolation and quantification, followed by detection under UV light, spraying the edges with 2’,7’-dichlorofluorescein, scraping off, elution with diethyl ether and weighting. Quantitative Ag-TLC (impregnated by dipping into 0.5 % or 2 % methanolic solution of silver nitrate) followed by detection with bromine and sulfuryl chloride vapor for 30 min each, followed by heating at 180-200 °C. Preparative Ag-TLC with 4 different mobile phases. Quantitative RP-TLC on Kieselguhr treated for 6 h with vapors of dimethyldichlorosilane and washed with methanol using acetone - acetonitrile - water. Quantitative determination by absorbance measurement at 450 nm.
J. Planar Chromatogr. 22, 97-100 (2009). TLC of (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, (-)-epicatechin gallate, (-)-epigallocatechin gallate, theaflavin, theaflavin 3-gallate, theaflavin 3’-gallate, and theaflavin 3,3’-digallate on polyamide phase in a horizontal chamber (saturated for 15 min) by twofold development with chloroform - methanol 2:3 or n-butanol - acetone - acetic acid 5:5:3. Separation of the flavonols myricetin, quercetin, kaempferol, rutin and the phenolic acids gallic acid, chlorogenic acid, and caffeic acid was achieved by twofold development with chloroform - methanol 2:3. Detection by spraying with iron(III) chloride solution and evaluation under daylight. Quantitative determination by absorbance measurement at 600 nm.
Anal. Chim. Acta 624 (1), 1-15 (2008). Aminoglycosides and macrolides are important antibiotics for veterinary medicine and are widely used in the treatment of bacterial disease, and as feed additives for growth promotion. As a result the European commission set strict criteria for monitoring residues and requires testing for low levels of aminoglycosides and macrolides in foods. Therefore the development of fast, reliable, and sensitive methods for the extraction and subsequent analysis of these antibiotics is of great interest. The review discusses analytical methods for both extraction and determination of antibiotics in various food matrices focusing on the last 10 years. Extraction and clean-up methods such as deproteinization and solid-phase extraction are described, and various screening methods including TLC, EI, CE, microbiological assays, and LC combined with MS are reviewed.
Quim. Nova 33, 43-47 (2010). HPTLC of aflatoxin B1 in peanuts on silica gel with chloroform - acetone 99:1. Quantitative determination by absorbance measurement at 366 nm, using a CCD camera followed by image processing using the software ImageJ. Linearity was between 0.8 and 4.8 ng/zone. The intra-day and inter-day precisions had a RSD lower than 5.2 %. LOD was 0.4 ng/zone while LOQ was 1.2 µg/kg. The average recovery was 94.9 %. The proposed method is a simple, efficient and low cost tool for quantitative analysis of aflatoxin B1 in peanut samples.
J. Sep. Sci. 33, 3794-3799 (2010). HPTLC of caffeine (1), theobromine (2) and theophylline (3) in different types of tea on silica gel with chloroform - dichloromethane - isopropanol 4:2:1. Quantitative determination by absorbance measurement at 254 nm. The hRF of (1), (2) and (3) was 65, 45 and 56, respectively. Limits of detection and quantification were 22 and 45 ng for (1), 23 and 46 ng for (2) and 22 and 43 ng for (3), respectively. The intra-day and inter-day precisions had a %RSD lower than 2.55 % (n=6) for all substances. Recoveries (by standard addition) were between 95.1-101.5 % for all the three methylxanthine derivatives. The values of LOD and LOQ obtained are similar with those obtained by HPLC.
