Abstract. The applicability of supercritical fluid extraction (SFE) in an undergraduate laboratory setting is demonstrated in this paper through a series of experiments. Using a commercial supercritical carbon dioxide (SCCO2) apparatus, the extraction of natural products was conducted from small trials to large scale with subsequent separation and purification of compounds of interest. When extraction is coupled with the analytical tools of NMR, GC-FID, and GC-MS, SFE can prove to be a valuable addition to the undergraduate teaching laboratory.
