title: [Purity testing of sorbose and sorbitol using thin layer chromatography on Silufol finished plates].
abstract: Different methods had been elaborated for proof and semiquantitative determination of mono-, di- and trisaccharides and of mannitol and sorbitol in sorbose as well as of mannitol, mono-, di- and trisaccharides in sorbitol following their separation by means of Silufol finished plates UV254. According to the results of sample mixtures, there is the possibility to separate from sorbose and to semiquantitatively determine 0.5% fructose and glucose each, 0.3 to 0.5% di- and trisaccharides as well as 1% sorbitol and 5% mannitol. Furthermore 0.5% fructose and glucose each, 0.3-0.5% di- and trisaccharides as well as 5% mannitol can be separated from sorbitol and semiquantitatively be determined.
