Isolation of Three Components from Spearmint Oil: An Exercise in Column and Thin-Layer ChromatographyDon R. Davies and Todd M. Johnson In this exercise, the three major components of spearmint oil, (+)-limonene, L-(-)-carvone, and (1R,2R,4R)-dihydrocarveol, are separated by silica gel column chromatography. The separation is monitored by thin-layer chromatography, and IR analysis is employed to verify the identity of the separated components. Davies, Don R.; Johnson, Todd M. J. Chem. Educ.2007, 84, 318.
