Lab: Identifying Plant Pigments by Chromatography
It is easy to extract the pigments from a leaf, but it is a challenge to separate and identify the distinct types of pigments from that mixture. Paper chromatography is a technique that allows the different plant pigments to be distinguished. Pigments are extracted onto the absorbent chromatography paper and the tip of the paper is dipped into a solvent. As the solvent soaks into the paper, the pigments dissolve and get carried along in the flow of solvent. After identifying the different pigments you will calculate the (Rf) of each pigment:
