Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that
