Fatty acids, from seed oils, and hydrocarbons, from diesel oil. Column open chromatography using silica impregnated with potassium hydroxide is another chromatographic method used to analyze copaiba oils. This modified silica works not only as a normal phase but as a cation exchange process too. This silica enables the elution of all the metabolites that are not carboxylic acids, which could be eluted with using methanol and mobile phase. Since copaiba oils have large amounts of diterpenic carboxilic acids, this kind of pre-fractionation is very useful and helps the isolation of the two classes of metabolites: sesquiterpenes and diterpenes.
