Differences in RF values between D- and L-tryptophan on cellulose paper, developed with water, were observed already in 1954 and now several variables of this separation, such as modifications to the tryptophan molecule, the temperature and salting-out have been examined. Differences were found in the mechanism of the process compared with the systems described by Yuasa et al. [Chromatographia, 21 (1986) 79], who separated amino acid enantiomers on cellulose with pyridine-ethanol-water mixtures.
