R. Bhushan et V. Parshad, Improved separation of vitamin B complex and folic acid using some new solvent systems and impregnated TLC, J LIQ CHR R, 22(10), 1999, pp. 1607-1623
TLC separation of vitamins of the 'B' complex group and folic acid has been
achieved on plates impregnated with different transition metal ions. The m
etal ions used were Mn++, Fe++, Co++ Ni++, Cu++, Zn++ and Hg++. hR(f) value
s for all the vitamins, using six new solvent systems,worked out for the pu
rpose, for each of the four different concentrations of each metal ion have
been reported. The results have been discussed for each metal ion compared
and the best conditions of separation have been identified.
