In the Laboratory
A Simplified Method for the Microscale Extraction of Pigments from Spinach
Kimberley R. Cousins and Kathleen M. Pierson
Department of Chemistry, California State University, San Bernardino, San Bernardino, CA 92407

October 1998
Vol. 75 No. 10
p. 1268

Abstract
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.
