Chromatography of the surrounding plant life.




Chromatography, in this case, was used in the process of extracting pigments from the vegetation we collected from the three sites. The three sites included a variety of plant species such as the palmetto, blackberry bushes, oak trees, wax myrtle, and Spanish moss. We then took these plant samples back to the lab and grinded them up into a fine paste. Next, we took the heated chromatography paper and applied the paste about a half-inch from the bottom of the paper. The chromatography paper was then placed into a chromatography solvent. The solvent’s job is to dissolve the different pigments in the paste and separate its components thus creating the various pigments found on the chromatography papers. In our own experiment, we got a variety of green and brown pigments from the plant life we collected.
