Part 2. Chromatographic applications. Anal. Chim. Acta 227, 155-163 (1989). TLC of coumarin-6-sulphonyl chloride derivatized amino acids on silica with chloroform – ethyl acetate – methanol – acetic acid 20:20:9:1. Detection by absorbance at 320 nm, or by spraying with ethanol, by fluorescence 366/>500 nm at 77°K. Detection limits in the ng level of analyte for both procedures.
J. Planar Chromatogr. 3, 311-316 (1990). Investigation of the chromatographic behavior of dansyl- (DNS), dinitrophenyl- (DNP), dinitropyridyl- (DNPy), and ß-naphthylamide-substituted amino acids, and alkaloids and polycyclic aromatic hydrocarbons (PAH) on layers of SilC18-50F and KC18-F developed with aqueous-organic solutions containing ß-cyclodextrin as chiral agent. For the first time the D and L enantiomers of DNP-Leu, DNPy-Leu, DNPy-Phe, and DNPy-Trp have been separated with ß-cyclodextrin in the mobile phase. The influence of the concentration of urea and of temperature on the separation factors of aromatic hydrocarbon has been studied.
J. Liquid Chromatogr. 16, 1845-1857 (1993). HPTLC on silica with benzene - triethanolamine 3:1 after derivatization with dansyl chloride. Quantification by fluoro densitometry.
J. Chinese Herb Med. (Zhongcaoyao) 26, 281-284 (1995). Isolation of a protein extracted from balsampear by DEAE-cellulose chromatography. Identification by chemical methods and polyacrylamide gel electrophoresis. The protein is composed of 17 kinds of amino acids. Analysis of the N-end amino acid (leucine) by two-dimensional TLC on DNS-amino acid-polyamide with 1.5% formic acid, and benzene - acetic acid 9:1 for the two directions, respectively. Detection under UV 365 nm.
J. Chinese Herb Med. (Zhongcaoyao) 27, 422-426 (1996). TLC of amino acids on silica with chloroform - methanol - formic acid 35:15:1. Detection by spraying with 0.2% ninhydrin in ethanol. TLC of steroids on silica with benzene - petrol ether 4:1. Detection by spraying with acetic anhydride - sulfuric acid - ethanol 1:1:10 and heating at 100°C for 15 min.
Biol. Chem. 379, 59-63 (1998). TLC of tyrosine and 3,4-dihydroxyphenyl-alanine (DOPA), as well as of adrenaline, noradrenaline and dopamine on silica gel with n-butanol ñ acetic acid ñ water 4:1:1. Detection with ninhydrin spray. Rf values: DOPA 0.29, adrenaline 0.36, noradrenaline 0.38, tyrosine 0.41, dopamine 0.43. Measurement of [3H]-radioactivity of DOPA by scintillation counting.
Planta med. 66, 418-423 (2000). TLC of b-pyrazol-1-yl alanine on silica gel with chloroform - methanol - water 13:10:3. Visualization by spraying with 2% methanolic ninhydrin solution and heating at 110°C for 10 min.
J. Planar Chromatogr. 19, 161-166 (2006). HPTLC of 16 amino acids on cellulose in a horizontal chamber with aqueous mixtures of 2-propanol, acetonitrile, and tetrahydrofuran in the range of 60-90 % (10 % increments). Acetic acid (at a concentration of 1%) was only added to the mobile phases containing 2-propanol. Best separation was achieved with tetrahydrofurane - water 17:3; acetonitrile - water 4:1; and 2-propanol - water - acetic acid 89.5 - 9.5 - 1 respectively. The adsorbed solvent was removed before repeating the development process. Visualization by spraying with ninhydrin solution and heating at 105 °C for 1.5-2 min. Densitometric evaluation by absorbance measurement at 415 nm.
