R. Bhushan et al., IMPROVED THIN-LAYER CHROMATOGRAPHIC RESOLUTION OF PTH AMINO-ACIDS WITH SOME NEW SOLVENT SYSTEMS, BMC. Biomedical chromatography, 8(2), 1994, pp. 69-72
Three new solvent systems, pyridine:benzene (2.5:20, v/v), methanol:ca
rbon tetrachloride (1:20, v/v) and acetone: dichloromethane (0.3:8, v/
v), for the resolution of a mixture of 18 PTH amino acids have been re
ported. Using these solvent systems, various combinations of PTH amino
acids which had previously posed resolution problems have been resolv
ed and identified.
