A method is presented for microscale sample preparation for the thin-layer chromatographic analysis of the pigments in spinach. A commercial vegetable juicer is used for the initial extraction from spinach. This is followed by filtration, liquid/liquid extraction, centrifugation, and evaporation. The new sample preparation technique is significantly more efficient than present methods and minimizes solvents used for extraction.
