J. Liq. Chrom. & Rel. Technol. 24, 1435-1445 (2001). TLC of chestnut pigments extracted from sawdust on silica gel and impregnated silica gel layers (prepared by overnight predevelopment in n-hexane - paraffin oil 19:1) with aqueous solutions of 2-propanol, tetrahydrofuran, and dioxane; multistep gradient elution for adequate TLC separations. Evaluation by densitometry at 340 nm. Identification by in-situ FTIR spectra.
Anal. Chem. 81, 8426-8433 (2009). HPTLC of zeaxanthin, cryptoxanthin, beta-carotene, lutein and pollen extracts on silica gel with tetrahydofuran - methylene chloride - n-hexane by automated multiple development. Quantitative determination by absorbance measurement at 425 nm, which has to be accomplished within 5 min after development due to the fast bleaching of the carotenoid color. The analysis of carotenoids in pollen extracts was confirmed by resonance Raman data measured directly on the HPTLC plates.
Food Chem. 239, 831-839 (2018). HPTLC of saffron on silica gel with 1-butanol – acetic acid – water 4:1:1. Qualitative identification at UV 254 nm. The hRf values of the nine detected zones (crocins and picrocrocin derivatives) were 19, 29, 43, 56, 63, 67, 80, 85, and 96. Captured images were imported to the MATLAB program for pattern recognition and discrimination between different saffron samples on the basis of their soil electro-conductivity values as indicator of soil salinity. The data pre-processing included elimination of chromatographic artifacts such as baseline drifts and spot misalignment.
A thin-layer chromatographic study. J. Chromatogr. 440, 275-280 (1988). Determination of the physico-chemical interactions between ascorbic acid and linear or cyclized bile pigment dimethyl esters by TLC on silica with benzene - methylene chloride - methanol 5:1:1. Use of the interacting barrier technique to establish a reactivity which is a function of the degree of cyclization of the molecule. Discussion of the results from spectrophotometric studies in connection with the possible biochemical role of the bilins.
Biochemical Systematics and Ecology 20, 761-769 (1992). TLC of glycosidic carotenoids on RP-18 silica with methanol - water 85:15.
J. Liquid Chromatogr. 18, 1663-1670 (1995). Preparative scale separation of the title compounds by centrifugal partition chromatography (CPC). Determination of the composition of the fractions by TLC on cellulose with 1-butanol - acetic acid - water 122:21:57. Identification by 1H NMR.
J. Liq. Chrom. & Rel. Technol. 25, 1521-1541 (2002). Overview over newest achievements in the field of the TLC separation of pigments present in various products, description and critical evaluation of the techniques, comparison of benefits and shortcomings of the separation methods. TLC and HPTLC of carotenoids, flavonoids and other pigments and pigment classes on a variety of sorbents using a wide range of eluents as mobile phases. Future trends in the separation and identification of pigments are delineated.
J. Planar Chromatogr. 23, 94-103 (2010). This review describes available data on analysis of carotenoids by TLC. Petroleum ether, acetone, and hexane are the major mobile phases used for TLC. This technique was found to have the potential to be the first choice for analysis of carotenoids in biological samples. The uses of other, orthogonal chromatographic methods, for example HPLC, MS, scanning densitometry, and image analysis with TLC can enable precise analysis of carotenoids. The review consists of the following parts: 1. Introduction; 1.1 Function of carotenoids; 1.2 Occurrence of carotenoids; 2. Analysis of carotenoids; 2.1 Sampling; 2.2 Sample preparation; 2.3 Extraction of carotenoids; 2.4 Saponification; 2.5 Chromatographic analysis; 3. Thin-layer chromatographic analysis of carotenoids; 3.1 TLC of carotenoids from microbial and animal sources; 3.2 TLC of carotenoids from plant sources; 3.3 Normal-phase TLC analysis of carotenoids; 3.4 Reversed-phase TLC analysis of carotenoids; 3.5 TLC analysis of carotenoids with scanning densitometry; 4. Advantages of TLC in carotenoid analysis; 5. Conclusion and future studies. 134 References.
