Supercritical fluid chromatography-gas chromatography of volatiles in cloudberry (Rubus chamaemorus) oil extracted with supercritical carbon dioxide

摘要

A supercritical fluid chromatographic-gas chroraatographic method was developed and applied to the analysis of volatiles of cloudberry oil extracted with supercritical carbon dioxide. Capillary supercritical fluid chromatography was used for the pre-separation of the oil and for the introduction of the volatile fraction into gas chromatography. Altogether 69 components could be reliably identified using chemical and electron impact ionization mass spectrometry. The major groups of compounds were arylcompounds and esters of fatty acids. The most abundant compounds were benzoic acid and benzyl alcohol with the relative amounts of approximately 58 and 6%, respectively.
