Some observations on thin layer chromatography technique

Abstract

The present study is to report the various problems faced during TLC methodology. Although used regularly some technical aspects must be kept in mind to get better and uniform results. During our experiments with TLC methods we came across some problems and here these aspects of TLC methodology are being highlighted. It is suggested that the solvent use as mobile phase should also be used for extraction of any particular phytochemical. TLC plates should be 3 to 4 mm thick, to be dried for at least 72 hrs. It is also suggested that potassium permanganate solution gives better clarity in visualizing the spots.
