Some solvent systems have also proved successful for thin-layer chromatography on silica gel of several mixtures from different . Requirements: TLC plate. HCl (pH 3.3); solvent equilibriation buffer, run buffer diluted 30 times (pH 3. . Then keep the chamber undisturbed for about 30 min so that the jar atmosphere becomes saturated with the solvent.1 Now cut the plate into perfect size and with the help of a pencil draw straight line across the plate from about 2 cm from the bottom. -butanol of chemically pure grade, decane of reagent grade, and hexane of reagent grade were used without additional purication. Thirty-nine dyes were subjected to thin layer chromatography to evaluate eight different solvent systems. Due to the COVID 19 epidemic, orders may be processed with a slight delay 1-Butanol/Acetic Acid/Water (4:1:5) This solvent system has a high polarity represented by low interfacial tension (< 1 dyne/cm), relatively high viscosity (1.63/1.40 c.p. Initially, the alcoholic extract of roots and leaves extract was subjected to thin layer chromatography.
