COLUMN CHROMATOGRAPHY EXTRACTION OF PIGMENTS …
users.stlcc.eduPurpose: To separate plant pigments from spinach leaves using column chromatography. The leaves of plants contain a number of colored pigments generally falling into two categories, chlorophylls and carotenoids. Chlorophylls a and b are the pigments that make plants look green. These highly conjugated compounds capture the (non-green)

LAB #6 Photosynthesis and Cellular Respiration
www.lamission.eduThe various plant pigments have differing degrees of hydrophobicity. Therefore, if we use a liquid solvent that is hydrophobic, different plant pigments will move at differing rates through the piece of paper as the liquid solvent is absorbed upward. In this way, individual pigments can be separated into bands on the filter paper.
